Structural changes alter the volume or size of specific brain regions. It looks to me as if the different functions merge into one another as we move from one area of the brain to an nearby area. Proper nervous system function involves coordinated action of neurons in many brain regions. But I think we already know enough about the brain to see some big patterns which correspond roughly to different functions. The term, 'reptilian brain' (or 'reptilian complex') is derived from a longstanding belief within the field of neuroanatomy that the forebrains of reptiles, and other small animals, were dominated by these structures. It’s not obvious (to me) that the brain can be divided up into different functions and separate chunks that perform those functions. 1 a : the portion of the vertebrate central nervous system enclosed in the skull and continuous with the spinal cord through the foramen magnum that is composed of neurons and supporting and nutritive structures (such as glia) and that integrates sensory information from inside and outside the body in controlling autonomic function (such as heartbeat and respiration), in coordinating and directing … Log in using the username and password we sent you.
