Researchers have established that the movement of the muscles in the jaw and tongue are governed by special neurons called motoneurons and that these are in turn controlled by another set of neurons called premotor
He designed an experiment in which participants would imagine playing tennis, a task that would normally lead to activity in the premotor
Mirror neurons were originally thought to be located in the lateral premotor
cortex of the brain but are now known to be more widespread and most likely exist in the posterior parietal cortex and the premotor
1998) Temporary interference in human lateral premotor
cortex suggests dominance for the selection of movements.
Diagnosis and the premotor
phase of Parkinson disease, Neurology 72: 12-20.
Emotional, cognitive and neurochemical alterations in a premotor
stage model of Parkinson's disease.
In this issue of EHP, a national group of experts reviews the current body of research on these premotor
symptoms, which may offer clues to better understanding the development of PD and identifying at-risk populations.
Species-specific response to human infant faces in the premotor
RESEARCHERS at University College may have found the answer: The sound of laughter activates the premotor
cortical region; the part of our brain that readies our facial muscles to react to sounds and this in turn makes us smile.
Likewise, the ventral premotor
cortex, which is a key structure for imitative (mirror neurons also in music activation) and tool-related actions (canonical neurons), showed a bilateral sexual preference-specific activation, suggesting that viewing sexually aroused genitals of the preferred sex triggers action representations of sexual behavior (Ponseti et al.
The reaction time is the time interval between the presentation of a stimulus and the initiation of a response, and it is fractionated into the premotor
and motor times.
A second helping of Krendler's brain--"most of the frontal lobe, back nearly to the premotor
cortex"--is also cooked and eaten before he becomes too obstreperous.
