Mirror Neurons and Premotor cortex leakage
The mirror is one of the strangest and most magical of human inventions. We look out at the external world, and see ourselves staring back. Mirrors are so ubiquitous that – for most people it is difficult to imagine a house without several – one in the bathroom, one in the bedroom, maybe others dotted round various rooms. We wash ourselves and shave and brush our teeth under our own gaze. At on...
متن کاملNeuronal activity in the ventral part of premotor cortex during target-reach movement is modulated by direction of gaze.
We recorded 200 neurons from the ventral part of the premotor cortex (PMv) and 110 neurons from the primary motor cortex (MI) of a monkey performing a visually cued arm-reaching task with a delay. We compared neuronal activity in the premovement period while the monkey reached the target with the eyes fixating on either a left or right fixation target. Our data demonstrate that about half of th...
متن کاملMirror Neurons Responding to Observation of Actions Made with Tools in Monkey Ventral Premotor Cortex
In the present study, we describe a new type of visuomotor neurons, named tool-responding mirror neurons, which are found in the lateral sector of monkey ventral premotor area F5. Tool-responding mirror neurons discharge when the monkey observes actions performed by an experimenter with a tool (a stick or a pair of pliers). This response is stronger than that obtained when the monkey observes a...
متن کاملCorticospinal Neurons in Macaque Ventral Premotor Cortex with Mirror Properties: A Potential Mechanism for Action Suppression?
The discovery of "mirror neurons" in area F5 of the ventral premotor cortex has prompted many theories as to their possible function. However, the identity of mirror neurons remains unknown. Here, we investigated whether identified pyramidal tract neurons (PTNs) in area F5 of two adult macaques exhibited "mirror-like" activity. About half of the 64 PTNs tested showed significant modulation of t...
متن کاملActivity in ventral premotor cortex is modulated by vision of own hand in action
Parietal and premotor cortices of the macaque monkey contain distinct populations of neurons which, in addition to their motor discharge, are also activated by visual stimulation. Among these visuomotor neurons, a population of grasping neurons located in the anterior intraparietal area (AIP) shows discharge modulation when the own hand is visible during object grasping. Given the dense connect...
