A mirror neuron is a neuron that fires both when an animal acts and when the animal observes the same action performed by another. Thus, the neuron "mirrors" the behavior of the other, as though the observer were itself acting. Such neurons have been directly observed in human and primate species, and birds.. In humans, brain activity consistent with that of mirror neurons has been found in MeSH: D Jun 02, · Track from "Dark Mirror Neurons" album - Released on May 22nd via Klonosphere/Season Of Mist Order LIVHZUENA album at faharderimarneusobisecocontge.co
The researchers found a small number of neurons that fired or showed their greatest activity both when the individual performed a task and when they observed a task. Other neurons had anti-mirror properties, that is, they responded when the participant performed an action but were inhibited when the participant saw that action. The mirror neurons found were located in the supplementary motor area and medial temporal cortex other brain regions were not sampled.
For purely practical reasons, these regions are not the same as those in which mirror neurons had been recorded from in the monkey: researchers in Parma were studying the ventral premotor cortex and the associated inferior parietal lobe, two regions in which epilepsy rarely occurs, and hence, single cell recordings in these regions are not usually done in humans. On the other hand, no one has to date looked for mirror neurons in the supplementary motor area or the medial temporal lobe in the monkey.
Together, this therefore does not suggest that humans and monkeys have mirror neurons in different locations, but rather that they may have mirror neurons both in the ventral premotor cortex and inferior parietal lobe, where they have been recorded in the monkey, and in the supplementary motor areas and medial temporal lobe, where they have been recorded from in human — especially because detailed human fMRI analyses suggest activity compatible with the presence of mirror neurons in all these regions.
Another study has suggested that human beings don't necessarily have more mirror neurons than monkeys, but instead that there is a core set of mirror neurons used in action observation and execution.
However, for other proposed functions of mirror neurons the mirror system may have the ability to recruit other areas of the brain when doing its auditory, somatosensory, and affective components. Although many in the scientific community have expressed excitement about the discovery of mirror neurons, there are scientists who have expressed doubts about both the existence and role of mirror neurons in humans.
According to scientists such as Hickok, Pascolo, and Dinstein, it is not clear whether mirror neurons really form a distinct class of cells as opposed to an occasional phenomenon seen in cells that have other functions and whether mirror activity is a distinct type of response or simply an artifact of an overall facilitation of the motor system. Dark Mirror NeuronsIlan Dinstein et al. InLingnau et al. They concluded that there was a significant asymmetry between the two processes that indicated that mirror neurons do not exist in humans.
They stated "Crucially, we found no signs of adaptation for motor acts that were first executed and then observed. Failure to find cross-modal adaptation for executed and observed motor acts is not compatible with the core assumption of mirror neuron theory, which holds that action recognition and understanding are based on motor simulation. InGreg Hickok published an extensive argument against the claim that mirror neurons are involved in action-understanding: "Eight Problems for the Mirror Neuron Theory of Action Understanding in Monkeys and Humans.
However, despite its widespread acceptance, the proposal has never been adequately tested in monkeys, and in humans there is strong empirical evidence, in the form of physiological and neuropsychological double- dissociations, against the claim. Vladimir Kosonogov sees another contradiction.
The proponents of mirror neuron theory of action understanding postulate that the mirror neurons code the goals of others' actions because they are activated if the observed action is goal-directed.
However, the mirror neurons are activated only when the observed action is goal-directed object-directed action or a communicative gesture, which certainly has a goal too. How do they "know" that the definite action is goal-directed? At what stage of their activation do they detect a goal of the movement or its absence? In his opinion, the mirror neuron system can be activated only after the goal of the observed action is attributed by some other brain structures.
Neurophilosophers such as Patricia Churchland have expressed both scientific and philosophical objections to the theory that mirror neurons are responsible for understanding the intentions of others.
In chapter 5 of her book, Braintrust, Churchland points out that the claim that mirror neurons are involved in understanding intentions through simulating observed actions is based on assumptions that are clouded by unresolved philosophical issues. She makes the argument that intentions are understood coded at a more complex level of neural activity than that of individual neurons. Churchland states that "A neuron, though computationally complex, is just a neuron. It is not an intelligent homunculus.
If a neural network represents something complex, such as an intention [to insult], it must have the right input and be in the right place in the neural circuitry to do that. Recently, Cecilia Heyes Professor of Experimental Psychology, Oxford has advanced the theory that mirror neurons are the byproduct of associative learning as opposed to evolutionary adaptation.
She argues that mirror neurons in humans are the product of social interaction and not an evolutionary adaptation for action-understanding. In particular, Heyes rejects the theory advanced by V.
Ramachandran that mirror neurons have been "the driving force behind the great leap forward in human evolution. Two closely related models postulate that mirror neurons are trained through Hebbian  or Associative learning    see Associative Sequence Learning.
However, if premotor neurons need to be trained by action in order to acquire mirror properties, it is unclear how newborn babies are able to mimic the facial gestures of another person imitation of unseen actionsas suggested by the work of Meltzoff and Moore.
One possibility is that the sight of tongue protrusion recruits an innate releasing mechanism in neonates. Careful analysis suggests that 'imitation' of this single gesture may account for almost all reports of facial mimicry by new-born infants.
Many studies link mirror neurons to understanding goals and intentions. Fogassi et al. The IPL has long been recognized as an association cortex that integrates sensory information. The monkeys watched an experimenter either grasp an apple and bring it to his mouth or grasp an object and place it in a cup. Only the type of action, and not the kinematic force with which models manipulated objects, determined neuron activity, Dark Mirror Neurons.
It was also significant that neurons fired before the monkey observed the human model starting the second motor act bringing the object to the mouth or placing it in a cup. Therefore, IPL neurons "code the same act grasping in a different way according to the final goal of the action in which the act is embedded.
Another possible function of mirror neurons would be facilitation of learning. The mirror neurons code the concrete representation of the action, i.
This would allow us to simulate to repeat internally the observed action implicitly in the brain to collect our own motor programs of observed actions and to get ready to reproduce the actions later. It is implicit training. This happens due to associative learning processes. The more frequently a synaptic connection is activated, the stronger it becomes. Stephanie Preston and Frans de Waal Jean Decety  and Vittorio Gallese   and Christian Keysers  have independently argued that the mirror neuron system is involved in empathy.
A large number of experiments using fMRI, electroencephalography EEG and magnetoencephalography MEG have shown that certain brain regions in particular the anterior insulaanterior cingulate cortexand inferior frontal cortex are active when people experience an emotion disgust, happiness, pain, etc. More recently, Christian Keysers at the Social Brain Lab and colleagues have shown that people who are more empathic according to self-report questionnaires have stronger activations both in the mirror system for hand actions  and the mirror system for emotions,  providing more direct support for the idea that the mirror system is linked to empathy.
Some researchers observed that the human mirror system does not passively respond to the observation of actions but is influenced by the mindset of the observer. Ramachandran has speculated that mirror neurons may provide the neurological basis of human self-awareness. I also speculated that these neurons can not only help simulate other people's behavior but can be turned 'inward'—as it were—to create second-order representations or meta-representations of your own earlier brain processes.
This could be the neural basis of introspection, and of the reciprocity of self awareness and other awareness. There is obviously a chicken-or-egg question here as to which evolved first, but The main point is that the two co-evolved, mutually enriching each other to create the mature representation of self that characterizes modern humans.
In humans, functional MRI studies have reported finding Dark Mirror Neurons homologous to the monkey mirror neuron system in the inferior frontal cortex, close to Broca's area, one of the hypothesized language regions of the brain. Mirror neurons have been said to have the potential to provide a mechanism for action-understanding, imitation-learning, and the simulation of other people's behaviour. Such speech repetition occurs automatically, fast  and separately in the brain to speech perception.
Further evidence for this link comes from a recent study in which the brain activity of two participants was measured using fMRI while they were gesturing words to each other using hand gestures with a game of charades — a modality that some have suggested might represent the evolutionary precursor of human language.
Analysis of the data using Granger Causality revealed that the mirror-neuron system of the observer indeed reflects the pattern of activity in the motor system of the sender, supporting the idea that the motor concept associated with the words is indeed transmitted from one brain to another using the mirror system .
The mirror neuron system seems to be inherently inadequate to play any role in syntaxgiven that this definitory property of human languages which is implemented in hierarchical recursive structure is flattened into linear sequences of phonemes making the recursive structure not accessible to sensory detection . The term is commonly used to refer to cases in which an individual, having observed a body movement, unintentionally performs a similar body movement or alters the way that a body movement is performed.
Automatic imitation rarely involves overt execution of matching responses. Instead the effects typically consist of reaction time, rather than accuracy, differences between compatible and incompatible trials. Research reveals that the existence of automatic imitation, which is a covert form of imitation, is distinct from spatial compatibility. It also indicates that, although automatic imitation is subject to input modulation by attentional processes, and output modulation by inhibitory processes, it is mediated by learned, long-term sensorimotor associations that cannot be altered directly by intentional processes.
Many researchers believe that automatic imitation is mediated by the mirror neuron system. For example, if the task is to maintain posture, people do it worse when they listen to sentences like this: "I get up, put on my slippers, go to the bathroom. The integration of research on motor mimicry and automatic imitation could reveal plausible indications that these phenomena depend on the same psychological and neural processes. Preliminary evidence however comes from studies showing that social priming has similar effects on motor mimicry.
Nevertheless, the similarities between automatic imitation, mirror effects, and motor mimicry have led some researchers to propose that automatic imitation is mediated by the mirror neuron system and that it is a tightly controlled laboratory equivalent of the motor mimicry observed in naturalistic social contexts. If true, then automatic imitation can be used as a tool to investigate how the mirror neuron system contributes to cognitive functioning and how motor mimicry promotes prosocial attitudes and behavior.
Meta-analysis of imitation studies in humans suggest that there is enough evidence of mirror system activation during imitation that mirror neuron involvement is likely, even though no published studies have recorded the activities of singular neurons.
However, it is likely insufficient for motor imitation. Studies show that regions of the frontal and parietal lobes that extend beyond the classical mirror system are equally activated during imitation.
This suggests that other areas, along with the mirror system are crucial to imitation behaviors. It has also been proposed that problems with the mirror neuron system may underlie cognitive disorders, particularly autism. Some researchers claim there is a link between mirror neuron deficiency and autism. EEG recordings from motor areas are suppressed when someone watches another person move, a signal that may relate to mirror neuron system.
This suppression was less in children with autism. Oberman and Ramachandran found typical mu-suppression for familiar stimuli, but not for unfamiliar stimuli, leading them to conclude that the mirror neuron system of children with ASD Autism Spectrum Disorder was functional, but less sensitive than that of typical children. Behavioural studies have shown that people with autism have a good understanding of action goals.
Furthermore, two independent neuroimaging studies have reported that the parietal component of the mirror system is functioning typically in individuals with autism. Some anatomical differences have been found in the mirror neuron related brain areas in adults with autism spectrum disorders, compared to non-autistic adults.
All these cortical areas were thinner and the degree of thinning was correlated with autism symptom severity, a correlation nearly restricted to these brain regions. Many researchers have pointed out that the "broken mirrors" theory of autism is overly simplistic, and mirror neurons alone cannot explain the differences found in individuals with autism.
First of all, as noted above, none of these studies were direct measures of mirror neuron activity - in other words fMRI activity or EEG rhythm suppression do not unequivocally index mirror neurons. Dinstein and colleagues found normal mirror neuron activity in people with autism using fMRI.
Instead, "additional research needs to be done, and more caution should be used when reaching out to the media. Research from  concluded that autistic individuals do not exhibit mirror neuron dysfunction, although the small sample size limits the extent to which these results can be generalized. In Philosophy of mindmirror neurons have become the primary rallying call of simulation theorists concerning our " theory of mind.
There are several competing models which attempt to account for our theory of mind; the most notable in relation to mirror neurons is simulation theory. According to simulation theory, theory of mind is available because we subconsciously empathize with the person we're observing and, accounting for relevant differences, imagine what we would desire and believe in that scenario. At the neuronal-level, in a study by Keren Haroush and Ziv Williams using jointly interacting primates performing an iterated prisoner's dilemma game, the authors identified neurons in the anterior cingulate cortex that selectively predicted an opponent's yet unknown decisions or covert state of mind.
These "other-predictive neurons" differentiated between self and other decisions and were uniquely sensitive to social context, but they did not encode the opponent's observed actions or receipt of reward. These cingulate cells may therefore importantly complement the function of mirror neurons by providing additional information about other social agents that is not immediately observable or known.
A series of recent studies conducted by Yawei Cheng, using a variety of neurophysiological measures, including MEG spinal reflex excitability,  electroencephalography,   have documented the presence of a gender difference in the human mirror neuron system, with female participants exhibiting stronger motor resonance than male participants. In another study, sex-based differences among mirror neuron mechanisms was reinforced in that the data showed enhanced empathetic ability in females relative to males.
During an emotional social interaction, females showed a greater ability in emotional perspective taking than did males when interacting with another person face-to-face. However, in the study, data showed that when it came to recognizing the emotions of others, all participants' abilities were very similar and there was no key difference between the male and female subjects.
Baland Jalal and V. Ramachandran have hypothesized that the mirror neuron system is important in giving rise to the intruder hallucination and out-of-body experiences during sleep paralysis.
The deafferentation of sensory information during sleep paralysis is proposed as the mechanism for such mirror neuron disinhibition. Recent research, which measured mu-wave suppression, suggests that mirror neuron activity is positively correlated with psychotic symptoms i. Researchers concluded that "higher mirror neuron activity may be the underpinning of schizophrenia sensory gating deficits and may contribute to sensory misattributions particularly in response to socially relevant stimuli, and be a putative mechanism for delusions and hallucinations.

Annual Review of Neuroscience. Current Biology. Archived from the original PDF on The Empathic Brain. Today, we present an interview with neuroscientist V. Ramachandran on mirror neurons, the subject of his Being Human talk.
Scientists have long wondered why we get that feeling, and more than two decades ago, a team of Italian researchers thought they stumbled on an answer. Since that time, mirror neurons have been hailed as a cornerstone of human empathy, language, and other vital processes. But there has also been something of a mirror neuron backlash, with some scientists suggesting that the importance of mirror neurons has been exaggerated.
See this post for more details. Below is a condensed version of our conversation. Jason Marsh: First, could you explain a little bit about what mirror neurons are and how they were discovered? Ramachandran: Well, basically Giacomo Rizzolatti and Vittorio Gallese and some of their colleagues in Italy discovered mirror neurons. They found these neurons in the frontal lobes of the brain—the pre-frontal areas of the brain—among what were originally found as motor command neurons.
These are regular motor command neurons, orchestrating a sequence of muscle twitches that allow me to reach out and grab something or do some other action. A subset of these neurons also fire when I simply watch another person—watch you reach out and do exactly the same action.
So these neurons are performing a virtual reality simulation of your mind, your brain. I wonder if you could elaborate on the role of mirror neurons in affective experiences, in emotional experiences. All I know is they are involved in empathy for, say, touch or a gentle caress or pain. For example, pretend somebody pokes my left thumb with a needle. We know that the insular cortex fires cells and we experience a painful sensation. The agony of pain is probably experienced in a region called the anterior cingulate, where there are cells that respond to pain.
The next stage in pain processing, we experience the agony, the painfulness, the affective quality of pain. It turns out these anterior cingulate neurons that respond to my thumb being poked will also fire when I watch you being poked—but only a subset of them. There are non-mirror neuron pain neurons and there are mirror neuron pain neurons. So these [mirror] neurons are probably involved in empathy for pain.
If I really and truly empathize with your pain, I need to experience it myself. JM: Just Dark Mirror Neurons clarify: When you talk about mirror neurons and non-mirror neurons, what percentage are you talking about? VR: Between 10 and 20 percent [are mirror neurons]. But these numbers are not all that accurate. JM: So could you elaborate on Dark Mirror Neurons social implications and broader practical implications of mirror neurons?
VR: Well, [mirror neurons] enable me to see you as an intentional being, with purpose and intention. In fact, we suggested nearly a decade ago that mirror neuron dysfunction may be involved in autism.
Jun 08, · Mirror neurons allow us to literally feel what others are feeling and “live” their emotions. Mirror neurons are based on empathy. Empathy is the ability to share someone else’s feelings or experiences by imagining what it would be like to be in that person’s situation. Nov 16, · For mirror neurons appear to let us “simulate” not just other people’s actions, but the intentions and emotions behind those actions. When you see someone smile, for example, your mirror neurons for smiling fire up, too, creating a sensation in your own mind of .
