Mirror neurons are a distinct class of neurons that discharge both throughout the execution of a motor act and in the course of observation on the similar or comparable motor act performed by an additional individual.On the other hand, the extent to which mirror neurons coding a motor act having a speciWc goal (e.g grasping) may well also respond for the observation of a motor act having the identical aim, but achieved with artiWcial eVectors, will not be yet established.In the present study, we addressed this issue by recording mirror neurons from the ventral premotor cortex (location F) of two monkeys educated to grasp objects with pliers.Neuron activity was recorded through the observation and execution of grasping performed using the hand, with pliers and for the duration of observation of an experimenter spearing meals using a stick.The results showed that virtually all neurons responding for the observation of hand grasping also responded towards the observation of grasping with pliers and, quite a few of them towards the observationof spearing with a stick.Having said that, the intensity and pattern of your response diVered among situations.Hand grasping observation determined the earliest plus the strongest discharge, whilst pliers grasping and spearing observation triggered weaker responses at longer latencies.We conclude that F grasping mirror neurons respond towards the observation of a household of stimuli leading for the identical goal.Even so, the response pattern depends upon the similarity among the observed motor act and the a single executed by the hand, the natural motor template.Monkey Mirror neurons Grasping Premotor cortex Tool use Purpose codingIntroduction A basic aspect of social life may be the capacity to know the meaning of others’ actions.Experiments carried out inside the last decade have shown that in daily life, despite the fact that not in unusual circumstances (Brass et al.; De Lange et al.; Liepelt et al), the capacity to understand others’ actions is mediated by the mirror mechanism (Gallese et al.; Rizzolatti et al).This mechanism transforms sensory details describing the acts of other individuals into a motor format related to the a single generated by the observer when preparing for or truly performing the observed behavior.The similarity among the motor representation generated in observation and that generated during motor behavior makes it possible for the observer to understand others’ actions, with no the necessity for inferential processing (Rizzolatti et al.; Rizzolatti and Craighero).One cortical region that consists of neurons endowed together with the mirror properties (“mirror neurons”) is F.This areaM.J.Rochat F.Caruana A.Jezzini L.Escola V.Gallese G.Rizzolatti M.A.Umilt Division of Neuroscience, University of Parma, Via Volturno , Parma, Italy e-mail [email protected] F.Caruana V.Gallese G.Rizzolatti M.A.UmiltItalian Institute of Technology, Section of Parma, Parma, Italy I.Intskirveli Department of Neurobiology and Behavior, University of California, Irvine, CA, USA F.TCS-OX2-29 Grammont Equipe Syst es Dynamiques, Interaction en physique, Biologie et Chimie (UMR CNRS) and Laboratoire de Neurobiologie (JE , Equipe Avenir INSERM), University of Nice, Good, FranceExp Brain Res forms the lateral part of the monkey ventral PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21330668 premotor cortex, and its activity is associated with the handle of hand and mouth movements (Kakei et al.; Matsumura and Kubota ; Rizzolatti et al.; Rizzolatti and Luppino).A vital characteristic of F neurons, regardless of regardless of whether they’re mirror neurons or motor neurons devoid.
