Document Summary
Influenced by 2 experimental and theoretical investigations into brain function: brain theory: states that the brain is the source of behaviour, neuron theory: states that the unit of brain structure and function is the neuron/nerve cell. In the long term, patient l. d. will show little recovery for higher brain functions (e. g. planning), but his golf game may improve. Sns: the parts of the cortex that produce movement mainly send information out via motor pathways to muscles on the opposite side of the body. Sensory and motor pathways also influence the muscles of internal organs (heartbeat, contraction of stomach, etc. : the pathways that control these organs are a subdivision of the pns called the autonomic nervous system (ans) Darwin: materialism: materialism rational behaviour can be explained by the workings of the nervous system, roots in evolutionary theories of wallace and darwin. Individual organisms within a species vary in their phenotype, traits we can see or measure: e. g. some big/tall/small/short/fast/slow.
