Cortex 0.8-1.1 0.8-1.1k and inner cortex lacking sclerotic clusters.
A comparable characterization of K-Channel expression in brain areas associated with speech and language (e.g. Broca's, orofacial and laryngeal motor cortex, etc). is lacking in humans, thus we cannot at present assess the degree of brain gene expression conservation across vocal learners.
Recordings made in adjacent primary motor cortex (M1) were reported as lacking mirror-like activity, and this was taken as evidence that the monkey was not making covert movements while it observed actions.
The motor cortex (M1) is classically considered an agranular area, lacking a distinct layer 4 (L4).
These small, scattered cells which receive input from the cerebellar lateral nucleus [24] project to the contralateral spinal cord via the rubrospinal tract and lack any input from motor cortex [25].
As a speech pathologist who treats people with brain injuries, I would argue that EEG activity in the motor cortex before making a decision may not necessarily represent a lack of choosing.
Against the background of established action observation effects on motor cortical activity, motor cortex activation induced by self-produced movements observed through a mirror is not lacking credibility.
Although beta-band oscillations in motor cortex have also been the subject of much experimental investigation, at present we still lack mechanistic functional models.
