PSYC 309 Lecture Notes - Lecture 8: Cerebral Cortex, Gyrus, Acetylcholine
Document Summary
Norepinephrine: bundles of neurons form a nerve, brain regions contains thousands of nerves. Brain surface features: gyrus: (pl. gyri) ridge on the cerebral cortex, sulcus (pl. sulci) groove on the cerebral cortex. 2: right and left hemispheres are connected by giant collections of fibers called commissures. Split brain: corpus callosum severed to reduce the effects of severe epilepsy. Hindbrain: brainstem: controls automatic processes that regulate basic life-support functions. Sleep cycles: damage can result in coma or death, contains regions that produce serotonin, norepinephrine etc. Hindbrain: cerebellum: balance and coordination of voluntary movements, damage makes it difficult to coordinate movements, such as walking, playing piano, also plays an important role in the ability to perform high-level cognitive tasks (learning, memory etc. ) Shallow layers: relay centers for sensory information entering the brain. Deep layers: motor activity, including eye movement. Damage: can cause problems in hearing, seeing and motor control.
