Document Summary

Structure of the brain: myelencephalon- medulla and origin of the reticular formation, metencephalon, cerebellum, pons. Mesencephalon: midbrain: tectum, superior colliculi, inferior colliculi, tegmentum, rostral end of reticular formation, periaqueductal gray matter, red nucleus, substantia nigra, ventral tegmental area. Telencephalon: cerebral cortex, basal ganglia, limbic system. Limbic system- regulation of motivated behaviours and memory: mammillary bodies, hippocampus, amygdala, fornix, cingulate, septum. Basal ganglia motor system: amygdala, striatum (caudate nucleus + putamen), globus pallidus. Cerebral cortex: convolutions increase cortical surface area, longitudinal fissure separates right and left cerebral hemispheres, corpus callosum largest commisure (hemisphere-connecting trait) Primary motor cortex: controls motor behaviour, broca"s area, speech production. Prefrontal cortex: executive functions, personality, emotion processing. Primary somatosensory cortex: language processing, visual spatial processing, association cortex. Primary auditory cortex: language processing, wernicke"s area, visual association cortex. Processes many aspects of vision: most of our brain is dedicated to vision.
