Jancke L, Shah N and Peters M (2000): Cortical activations in primary and secondary motor areas
for complex bimanual movements in professional pianists.
PENFIELD, W & WELCH, K 1951: The supplementary motor area
of the cerebral cortex: A clinical and experimental study.
This increase in MRCP is encouraging because nonprimary motor areas
are known to be involved in stroke motor recovery .
It is interesting that this system does not influence movement through spinal cord pathways, but rather acts as part of a feedback loop to all areas of the cerebral cortex, with primary input into motor areas
Specifically, the team found increased activity in the premotor cortex and the supplemental motor area
(both right under the crown of the head).
While the motor area
is responsible for sending nerve impulses to the muscles to make them move, the premotor area is where the thought originates to initiate movement.
A new fan system keeps a consistent flow of air in the motor area
, regardless of belt speed, to reduce motor temperature and allow for greater torque.
However, when imagining sentences in another person's voice, hallucinators showed reduced blood flow in the supplementary motor area
(SMA) and the left middle temporal gyrus (MTG), the scientists report in the Sept.
As a previous PET study had noted, the repetitive taps activated the primary motor cortex, while the sequences demanded that the motor cortex, a supplementary motor area
, and two other regions become active.
Brain imaging studies have found activation of motor areas
when people process action-related words.
Islamabad -- A University of Vermont College of Medicine child psychiatry team has found evidence they expected that music playing altered the motor areas
of the brain, because the activity requires control and coordination of movement and changes were observed in the behaviourregulating areas of the brain.
such observation not only activates the brain's visual areas, it is also registered in the [relevant] motor areas
