What does SMA stand for?

Supplementary motor area structure and function: review and hypotheses.

used single photon emission computed tomography to show that several brain areas were active during overground walking in healthy subjects, including supplementary motor area (SMA), medial primary somatosensory cortex (S1), striatum, cerebellum, and visual cortex [57].

For example automatic control of overlearned sequences of movement (such as walking) are generally considered to be under the control of the basal ganglia which send an internal prompt to the supplementary motor area to release each subcomponent in the sequence of movement.

35) Compared to religious practitioners who had never had such an experience, it was determined that the converted group had significantly increased blood flow to the supplementary motor area (linked to the planning of motor acts), the right dorsolateral prefrontal cortex (linked to memory retrieval and monitoring of thought) and the right pre-cuenus (linked to visual working memory).

Speech is controlled by the supplementary motor area of the brain and getting anxious about a word kicks off activity in this area, sending it into overdrive.

However, men show more activity in a region known as the supplementary motor area of the brain -- which means better spatial skills.

But with memory tasks, like map reading, men show more activity than women in the brain region known as the supplementary motor area.
