Corticospinal mirror neurons

Corticospinal mirror neurons

Here, we report the properties of neurons with mirror-like characteristics that were identified as pyramidal tract neurons (PTNs) and recorded in the ventral premotor cortex (area F5) and primary motor cortex (M1) of three macaque monkeys. We analysed the neurons' discharge while the monkeys performed active grasp of either food or an object, and also while they observed an experimenter carryin...

M1 Corticospinal Mirror Neurons and Their Role in Movement Suppression during Action Observation

Evidence is accumulating that neurons in primary motor cortex (M1) respond during action observation, a property first shown for mirror neurons in monkey premotor cortex. We now show for the first time that the discharge of a major class of M1 output neuron, the pyramidal tract neuron (PTN), is modulated during observation of precision grip by a human experimenter. We recorded 132 PTNs in the h...

Corticospinal 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...

Mirror neurons

The term mirror neurons originally referred to neurons in the ventral premotor cortex of macaque monkeys (area F5, Figure 1a) that have the particularity of responding both when the monkey performs a particular action (e.g., grasping a peanut) and when the monkey perceives another individual performing a similar action. More recently the term mirror has been extended to areas of the human brain...
