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 similar motor act performed by an additional individual.However, the extent to which mirror neurons coding a motor act with a speciWc purpose (e.g grasping) could also respond for the observation of a motor act possessing the exact same purpose, but achieved with artiWcial eVectors, is not yet established.In the present study, we addressed this concern by recording mirror neurons in the ventral premotor cortex (location F) of two monkeys trained to grasp objects with pliers.Neuron activity was recorded during the observation and execution of grasping performed with the hand, with pliers and in the course of observation of an experimenter spearing food with a stick.The results showed that virtually all neurons responding for the observation of hand grasping also responded to the observation of grasping with pliers and, quite a few of them for the observationof spearing with a stick.Nonetheless, the intensity and pattern on the response diVered among circumstances.Hand grasping observation determined the earliest and the strongest discharge, even though pliers grasping and spearing observation triggered weaker responses at longer latencies.We conclude that F grasping mirror neurons respond for the observation of a family members of stimuli major to the same aim.However, the response pattern depends upon the similarity among the observed motor act and also the 1 executed by the hand, the all-natural motor template.Monkey Mirror neurons Grasping Premotor cortex Tool use Aim codingIntroduction A basic aspect of social life is the capacity to understand the meaning of others’ actions.Experiments carried out within the final decade have shown that in everyday life, although not in uncommon 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 folks into a motor format related for the 1 generated by the observer when preparing for or really performing the observed behavior.The similarity in between the motor representation generated in observation and that generated throughout motor behavior enables the observer to understand others’ actions, without the necessity for inferential processing (Rizzolatti et al.; Rizzolatti and Craighero).1 cortical region that contains neurons endowed 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, Via Volturno , Parma, Italy email [email protected] F.Caruana V.Gallese G.Rizzolatti M.A.UmiltItalian Institute of Technology, Section of Parma, Parma, Italy I.Intskirveli Division of Neurobiology and Behavior, University of California, Irvine, CA, USA F.Grammont MedChemExpress FIIN-3 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 types the lateral part of the monkey ventral PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21330668 premotor cortex, and its activity is related to the manage of hand and mouth movements (Kakei et al.; Matsumura and Kubota ; Rizzolatti et al.; Rizzolatti and Luppino).An essential characteristic of F neurons, regardless of regardless of whether they’re mirror neurons or motor neurons devoid.
