Document Summary
Lecture two motor cortex neural signals --> muscle contraction --> movement signals comes from brain => spinal cord => motor neurons => muscle variations of movements comes from different levels of contraction + change in muscle length. 1. frontal lobe: parietal lobe, occipital lobe temporal lobe. Premotor cortex, important for movement selection and preparation, especially imvolved in when movement involves a response to visual cue the location of mirror neutons supplementry motor area (sma), important in production of movement sequences. Next -> subcortical motor control structures the cerebellum and the basal ganglia o o o o o. 1. the cerebellum means little brain in latin o o. It adjusts movements so that they occur as planned: cerebrocerebellum: important in the timing and initiation of movement cerebella diseases or damaged can produce impaired balance, disruption to the comtrol of limb and eye movements.
