Document Summary
Cerebrum: largest part of the brain, right and left hemispheres. Frontal lobe motor cortex, higher mental processes. Parietal lobe sensation and perception, integration of sensory input. Temporal lobe hearing, smelling, learning, memory, visual aspects and emotion: corpus callosum, 3 areas of grey mater. Covers the surface of the cerebral hemispheres. Stellate and pyramidal cells (names after shapes. Process sensory input to the cortex: pyramidal cell (pyramid-shaped) Basil nuclei or basil ganglion involved with movement. Part of a feedback loop connecting cerebral cortex, basal nuclei and thalamus. Limbic system different regions of the brain. Modern conceptions of anatomy of limbic system includes: medial cortical areas (cingulate gyrus included, anterior group nuclei of thalamus, amygdala, hippocampus, hypothalamus, some basal forebrain structures (mostly notably the septal area) Motor control in the brain: supplementary motor area. Complex sequences of movement: premotor cortex. Orienting the body and arms toward a target: posterior parietal cortex. Processes sensory input concerning spatial context: cerebellum.
