Mirror neurons are a distinct class of neurons that discharge each throughout the execution of a motor act and in the course of observation on the exact same or equivalent motor act performed by an additional person.Having said that, the extent to which mirror neurons coding a motor act with a speciWc target (e.g grasping) could possibly also respond for the observation of a motor act having the same aim, but achieved with artiWcial eVectors, just isn’t however established.Within the present study, we addressed this situation by recording mirror neurons from the ventral premotor cortex (area F) of two monkeys trained to grasp objects with pliers.Neuron activity was recorded in the course of the observation and execution of grasping performed with all the hand, with pliers and during observation of an experimenter spearing meals having a stick.The outcomes showed that virtually all neurons responding towards the observation of hand grasping also responded for the observation of grasping with pliers and, lots of of them for the observationof spearing with a stick.Nevertheless, the intensity and pattern from the response diVered among conditions.Hand grasping observation determined the earliest and the strongest discharge, though pliers grasping and spearing observation triggered weaker responses at longer latencies.We conclude that F grasping mirror neurons respond to the observation of a loved ones of stimuli leading for the same objective.Nevertheless, the response pattern depends upon the similarity between the observed motor act as well as the one executed by the hand, the organic motor template.Monkey Mirror neurons Grasping Premotor cortex Tool use Aim codingIntroduction A fundamental aspect of social life is the capacity to know the meaning of others’ actions.Experiments carried out in the last decade have shown that in each day life, even though not in unusual conditions (Brass et al.; De Lange et al.; Liepelt et al), the capacity to know others’ actions is mediated by the mirror mechanism (Gallese et al.; Rizzolatti et al).This mechanism transforms sensory info describing the acts of other individuals into a motor format related to the one particular generated by the observer when preparing for or really performing the observed behavior.The similarity involving the motor representation generated in observation and that generated during motor behavior permits the observer to understand others’ actions, with out 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 Department of Neuroscience, University of Parma, By means of Volturno , Parma, Italy e mail [email protected] F.Caruana V.Gallese G.Rizzolatti M.A.UmiltItalian Institute of Technologies, Section of Parma, Parma, Italy I.Intskirveli Department of Neurobiology and Behavior, University of California, Irvine, CA, USA F.Grammont Equipe Syst es Dynamiques, Interaction en physique, Biologie et Chimie (UMR CNRS) and Laboratoire de Neurobiologie (JE , Equipe Avenir INSERM), University of Nice, Nice, FranceExp Brain Res types the lateral a part of the monkey ventral PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21330668 premotor cortex, and its activity is associated with the control of hand and mouth movements (Kakei et al.; Matsumura and Kubota ; Rizzolatti et al.; Rizzolatti and Luppino).An important characteristic of F neurons, no matter irrespective of whether they are mirror neurons or motor neurons devoid.
