When she thought about playing tennis, the supplementary motor cortex, which is involved in planning movements, became active, but when she imagined walking through her house, the parahippocampal gyrus, which is needed for spatial navigation, was activated.
When subjects are asked to indicate the time it takes to view a series of pictures, heightened activity is measured in the centers that control muscular movement, primarily the cerebellum, the basal ganglia and the supplementary motor area.
On the medial surface of the hemisphere, in front of the motor strip, is the supplementary motor area.
They found the main difference between the two conditions was the level of activation in a cortical region known as the supplementary motor area (SMA), which contributes to the control of movement.
Supplementary motor area.
The supplementary motor area (SMA) plays an important role in the regulation of motor function.
The supplementary motor area (SMA) is a key node of the motor network.
In the motor cortex different nonlinear behavior was found in the primary and supplementary motor cortexes.
These effects seemed to be derived from the supplementary motor area (SMA).
We also observed activation in the supplementary motor area (SMA) during count as well as respond.
Both groups showed robust activation of visual, motor, somatosensory, and supplementary motor regions.
