lisäaivokuori
Lisäaivokuori, also known as the supplementary motor area (SMA), is a region of the cerebral cortex located in the frontal lobe of the brain, anterior to the primary motor cortex. It plays a crucial role in the planning and sequencing of movements, particularly those that are internally generated or complex. Unlike the primary motor cortex which directly executes movements, the SMA is involved in higher-level motor control.
Research suggests the SMA is involved in preparing for movement, selecting appropriate motor programs, and coordinating
Damage to the SMA can result in a range of motor deficits, including apraxia, which is difficulty
