Document Summary
Biological psychology, by definition, is the study of physical and chemical changes involved in behaviour and mental processes. Brain structures can operate in multiple systems to perform key functions. That is to say that the biological structure of our nervous system defines its capabilities. For instance, the olfactory bulbs (brain regions contributing to our sense of smell) are much larger and more complex in dogs than in humans. For instance, multiple sclerosis an autoimmune disease affecting the myelin insulating neuronal axons can slow down signal transduction resulting in slowed reaction times and reflexes. An example of a neurological disease affecting the output stage of processing is parki(cid:374)so(cid:374)"s disease, (cid:449)here(cid:271)(cid:455) muscle rigidity (dystonia) cannot be controlled by the brain without external dopamine medication. Two types of cell: neurons(brain structure) and glia(chemical and electrical transmission) Key functions of the nervous system and body are information processing.
