Add CommentWhy are mirror neurons considered to be part of a special kind of recognition capability rather than just evidence that the brain has concept encodings that are referenced in multiple instances and situations, such as seeing someone else do something, thinking about oneself doing it, reading about it, seeing a photograph of it, etc.?
Reply | Report Abuse | Link to thisMy question is the same: what proof correlates them to this special recognition? Also, what is the proof that they are entirely (or nearly entirely) for social situations?
Reply | Report Abuse | Link to thisI feel that the presence of mirror neurons explains much of psychology, such as peer pressure, loneliness, and attention to aspects. I have termed all perception as direct/indirect, with indirect being the subconscious processes that occur while observing all else. It would probably also play a large role in cognition, such as imagining a logical situation or making sense of religion.
Reply | Report Abuse | Link to thisMirror neurons have become the latest "homunculus". People think they magically explain complex phenomena without providing a serious theory of how they can behave the way they do. Obviously they are "over-hyped" and Dr. Iacoboni has had a big part in this. But if we look at his "research" on brain and politics (for example), this should come to no surprise.
Reply | Report Abuse | Link to thisI agree that mirror neurons are the stuff of which myths and legends are made- in fact, one could hypothesize that mirror neurons fire very intensely to behaviors, ideas, and persons who excite us, and the initial discovery itself generated quite a bit of excitement. Much rigorous research remains to be done. However, I do think that mirror neurons do highlight the fact that some brain systems and centers carry out complex social "analyses" that we have heretofore ascribed to conscious cogitation and deliberation. This in itself is a very important and fertile area for investigation. I don't think that mirror neurons should be dismissed as mere hype.
Reply | Report Abuse | Link to thisI am interested in group dynamics, and am wondering if any readers have ideas about how mutual "mirroring" in a group might combine to account for group dynamics such as conformity, scapegoating, etc.
Has any research looked into different responces of mirror neurons in males and females? People often anecdotally say women are more socially aware, or empathetic than men (in general) - perhaps females have more active mirror neurons?
Reply | Report Abuse | Link to thisPeople also talk of 'bonding' with a new born child - again reported more in the mothers. Perhaps a real physical change in the brain occurs for this bonding to take place - say, mirror neurons somehow tune in to the new-born's face...? Just spectulating of course but maybe there is something in it.
Reply | Report Abuse | Link to thisSure, try these. I am just now finishing two texts which having been published at about the same time cover the same topics and cite in many cases the same research, but each author writes from a different perspective (there are probably many more texts--I chose these based on price and availability):

These types of texts are comprehensive and can be best appreciated in the context of human social history, especially when such history is so relevant to world peace.

However, please keep your mind open to learning something about neuroscience. It is a complex subject that can be better appreciated with some basic introduction, particularly about neurobiology and how brain science is conducted in the laboratory:

Biological Psychology
by James W Kalat
Dr. James W. Kalat's BIOLOGICAL PSYCHOLOGY is the best selling text in the market because of its extremely high level of scholarship, clear and occasionally humorous writing style, and precise examples integrated throughout the text. Throughout all nine editions, the goal has been to make biological psychology accessible to psychology students, ...
The philosopher-linguist and social psychologist George Herbert Mead (1863 - 1931) created the core of his work, which he labeled symbolic interaction, around the idea that somehow, human's must have evolved the ability to mirror other people's gestures -- that our use of symbols in language is based on this mirroring. I am astonished to see this development in science and wonder if anyone knows of any papers relating this work on mirror neurons to Mead's work on gestures, language and identity.

Reply | Report Abuse | Link to thisWe are independent researchers studying mirror neurons and have recently come to conclusion that the results of the experiments conducted by Iacoboni et al (2005) do not support the notion that mirror neurons code intention. If you are interested, we would like send you work entitled "The Link Between Mirror Neurons and Intention (Iacoboni et al 2005) Is Subject To Further Investigation." Abstract attached.

ABSTRACT
This work will analyze the findings of Iacoboni et al., 2005 wherein is stated the human mirror neuron system does not simply provide an action recognition mechanism, but also constitutes a neural system for coding the intentions of others and will suggest that the findings are not supported by the results of the experiments.
The analysis of Iacoboni's findings demonstrates that the alleged greater activity in mirror neuron areas in the inferior frontal cortex in the Intention cleaning condition did not show sufficient additional activity to support the principal finding.
The analysis demonstrates that alleged greater activity in mirror neuron areas in the inferior frontal cortex in the Intention drinking condition is not valid since the comparison between Action, Intention drinking and Intention cleaning conditions was not based on the premises of the hypothetical model (identical grasping actions), thus, leading to an improper reading of the data and interpretation of the findings.
The high response in the Intention drinking condition versus Action and Intention cleaning is attributed instead to differences in the types of grasping actions, implemented by Iacoboni and observed by participants. These differences affect the level of mirror neuron response. The high level reported in the Intention drinking is due to the instantaneous recognition of two actions, grasping and bringing to the mouth. These are found to be two consecutive and adjoining links within the drinking action. The lack of additional response in Intention cleaning is due to the recognition of only the grasping action by viewing the Intention cleaning clip. Consequently, the need to resort to the understanding of intention to account for the high response (in the Intention drinking condition) can be eliminated.
I am interested in knowing whether mirror neurons only applies to visual behavior, or whether any research has been done regarding auditory imitation of sounds..... please refer me to such papers.

Thank you for this informative article. I would like to submit that the mirror neuron difference in autistic people can lead to feelings of isolation (such as the saying "all alone in a crowded room"). I have experienced this with my own autism and with my autistic students. I wonder if the absence of stimulation from others actions and emotions leads to self-stimulating behaviors and sensory-seeking.

Hi there,
Reply | Report Abuse | Link to thisI am interested in finding out if mirror neurons are really that special, or if they are simply another example of autoassociation.
That is, many people (particularly lay people, in areas such as management), are "listening in" on this research, and jumping to all kinds of conclusions. Many people believe that the responses of such neurons are innate (i.e. we are "wired" to recognise the emotions of others).
As there is not enough information in the genome to hardwire such connections (e.g., how could you possibly know the neural representation of how a smile is represented in the visual cortex from birth), I am thinking, that such systems need to be "learned" from experience.
I am thinking that simple autoassociation could explain such circuitry. E.g., when I am in a social situation and there is a shared experience that makes me and others happy, the visual representation of others' smiles, will be autoassociatively linked to my own internal states (e.g., motor representation of smiling, and associated affect). Similarly, there is sufficient overlap in visual representation between my hand grasping an object, and others' hands, to illicit similar visual recognition.
Thus, yes, mirror neurons are cool in that you may be able to learn from others vicariously, and empathise better etc. etc., but is it REALLY a special mechanism at play, or is it simply a nice example of general self-organisation principles of the brain, such as autoassociation.
Interested to hear others' thoughts.
