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.
What Is the Primary Motor Cortex? Every voluntary movement you make is controlled through the primary motor cortex (PMC), which is located in the back of the frontal lobe, just about at the top of your head. Signals in your brain are sent to the muscles, telling them to make a movement.
