Document Summary
Evolution of brain size and human behaviour. The human brain has optima overall size (size and number of neurons, number and length of connections, energy consumption). Changing these features would compromise others and neutralize any improvements in performance. The brain"s primary function is to produce behaviour (movement) Integrate information to construct a subjective experience of reality (perception). Produce commands to control the movement of muscles. Anatomical divisions of the nervous system: anatomic organization, functional organization. The frame of reference is the face. The frame of reference is the whole body. Direction of a cut, or section, through the brain (part a) from the perspective of a viewer (part b) The afferent nerve carries information from sensory receptors in skin to the brain. The efferent nerve carries the brain to the neurons controlling leg muscle, causing a response. Areas of the nervous system rich in fat-sheathed neural axons. Areas of the nervous system predominantly composed of cell bodies and blood vessels.
