14.1 Introduction
Mary Ann Clark; Jung Choi; and Matthew Douglas
While you are reading this book, your nervous system is performing several functions simultaneously. The visual system processes what is seen on the page; the motor system controls the turn of the pages (or click of the mouse); the prefrontal cortex maintains attention. Even fundamental functions, like breathing and regulation of body temperature, are controlled by the nervous system. A nervous system is an organism’s control center: it processes sensory information from outside (and inside) the body and controls all behaviors—from eating to sleeping to finding a mate.
