Document Summary

Cells: provide regulatory function (nedergaard, ransom, and goldman 2003, trends neurosci) Axon: part of cell that allows cells to communicate. Cortex: outer layer of brain, cortical labels define where bumps, grooves, fissures, lobes and lobules are located. Structure of cortex: gross similarities between all brains (hemispheres, lobes, lobules, gyri, sulci) fine similarities (cytoarchitecture, layering) and functional similarities. Lobule: smaller than a lobe, larger than gyrus. Intraparietal sulcus: central sulcus, sylvian fissure, calcarine fissure. Cytoarchitechture: cellular composition, brodmann"s areas numbered regions differentiated by relative distribution of cell types across cortical layers (ba"s) 52. Ba"s, gives more precision to what we are looking for within the brain. Layering: most cortex have 6 layers some have 4-5. Neocortex: 6 layers, outer most part of brain. Mesocortex: surrounds allocortex, paralimbic region, and connects old information with new. Sensory: primary sensory cortex: 1st part of brain to get information. Motor: primary motor cortex: last cortical area before motor output.
