Document Summary

Chapter 2: biology of the mind (part 2) Central ns (brain and spinal cord; mostly interneurons: spinal cord connects pns to brain and mediates sensory inputs. Peripheral nervous system (most sensory and motor neurons here: autonomic ns: controls self-regulated action of internal organs. Enteric ns: controls gut; works indecently of rest of system: somatic: controls voluntary movements. Also affects behaviour and thinking, and operation of ans. Endocrine transmission are slower than neural transmission; but have longer lasting effects. Brainstem/thalamus: supports life-sustaining bodily functions: pons: controls/regulates sleep, breathing, swallowing, bladder function, hearing, taste, eye movement, posture, facial expressions (all of these are lower functions of the brain) Ability to recognize members of the same or different species (present in humans, primates, and some mammals) If all other brain functions stopped, pons would allow you to breathe and have heart function (vegetative state: medulla: controls heartbeat and breathing (basic body functions)
