NROB60H3 Lecture Notes - Lecture 4: Oligodendrocyte, Behavioral Enrichment, Schwann Cell
Document Summary
The cortex is divided into four major lobes: frontal. Voluntary movement, expressive language, executive functioning, working memory, etc: temporal. Hearing, smell, long-term memory, receptive language, etc: parietal. Somatosensation (touch, pain, and temperature), speech comprehension and reading ability, production of writing and calculation, visual-spatial functioning, etc: occipital. Major sensory, motor, and association areas of cortex: primary motor cortex. Controls movement of the contralateral (opposite) side of the body: primary sensory cortex. Involved in sensation from contralateral (opposite) side of the body: association areas. Involved in higher order processing for separate sensory/motor modalities, as well as the integration of multiple modalities. Regional classification: in 1909, korbinian broadmann divided the cortex into 52 cytoarchitectonic areas where each was assigned a number according to the order in which he prepared his slides. Primary motor cortex, supplementary motor area, and premotor area are all in the frontal cortex. Association areas are more wide spread: prefrontal cortex, posterior parietal cortex, and inferotemporal cortex.
