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.
Damage to the primary auditory cortex results in the inability to interpret pitch, loudness, and location. Damage to the primary motor cortex results only in the loss of both voluntary muscle control and reflexes. Damage to the premotor cortex results in loss of motor skills programmed in that area but movement is still possible. Damage to the primary visual cortex results in functional blindness.
