Document Summary
Psyc31 chapter 3: the behavioral geography of the brain. New neurons are produced in some brain regions of adults in a number of mammalian species, playing a role in brain injury repair, new learning, and maintenance of healthy neural functioning. Adult neurogenesis has been identified in the hippocampus and olfactory bulb in mammalian brains and implicated in other limbic regions, in the neocortex, straitum, and substantia nigra. Neurogenesis in the hippocampus is thought to be especially critical for maintaining normal cognition and emotional well-being. Basal ganglia and cerebellum are increasingly appreciated for their influences on cognition and psychiatric disorders. Motor cortex appears to play an active role in processing abstract learned information. Strategically occurring lesions or abnormalities albeit small may nonetheless influence neuropsychological functions. Any given behavior is the product of a myriad of complex neuropsychological and biochemical interactions involving the whole brain.
