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.
Areas of the motor cortex Edit. The motor cortex can be divided into five main areas: 1  the primary motor cortex (or M1), responsible for generating the neural impulses controlling execution of movement.2  and the secondary motor cortices, including. 3  the posterior parietal cortex, responsible for transforming visual information into motor commands.reas of the motor cortex Edit.
