The oldest, and most commonly used, is the USDA Zone Hardiness map which calculates 11 zones and tells what level of winter cold a plant could experience in a location. Seattle falls into zone 8b with expected winter minimums of 15 to 20.
Motor cortex. (Redirected from Secondary motor cortex) The motor cortex is the region of the cerebral cortex involved in the planning, control, and execution of voluntary movements. Classically the motor cortex is an area of the frontal lobe located in the posterior precentral gyrus immediately anterior to the central sulcus.
In fact, the brain's motor functions have many points in common with its sensory mechanisms, especially those involved in tactile sensations. Thus, the primary motor cortex, in the posterior portion of the frontal lobe, is immediately adjacent to the somatosensory cortex, in the anterior portion of the parietal lobe.he basal ganglia play an indirect role in the motor system. By projecting to the motor cortex, the premotor cortex, and the supplementary motor area simultaneously, they form part of the corto-basal ganglia motor loop, which determines and controls what movements will be performed.
