Document Summary

Topic: neuroscience ii neuropsychological and cognitive neuroscience. Many thought the brain was equipotential entire brain had same function without specialization. Two halves to the brain: left hemisphere language and speech, right hemisphere 3d space and spatial relationships. Brainstem connects brain to spinal cord: oldest part of brain, automatic behaviours, relay sensory information. Identify the major structures, their function and location. Identify the six subcortical structures, their location and function: describe the basic brain structures and their functions. Midbrain brainstem, cerebellum, hypothalamus: structures only occur once, two structures for: thalamus, basal ganglia, limbic system, cortex, one in each cerebral hemisphere. Cerebral hemisphere = grey + white matter: sit on top of subcortical structures under cortex. Thalamus controls most sensory information to cortex. Gateway" to cerebral cortex: sleep = shuts incoming sensations while brain rests. Basal ganglia control movement: voluntary movement automated response is called procedural memories. Limbic system emotions, memories, stimulation: amygdala emotional learning, hippocampus memory, learning, conscious retrieval (declarative memory)
