NROB60H3 Lecture Notes - Diencephalon, Brainstem, Neocortex
Document Summary
Early observations of structure led to interpretations about function: this was done by damaging certain parts of the brain to figure out the function. Constantly refined as new data is available. Advances in technology and in knowledge: we can now make observations on function without having to damage parts of the brain. Slide 4: understanding the cns structure through development. Special features of the human cns: similarities in rate and human brain. Special features of the human cns: differences. Convulations on human cerebrum surface called sulci and gyri. Growth of cerebral hemisphere: temporal, frontal, parietal, occipital. Hemispehres are separated by a deep sagittal fissure. Clearly split down the middle into two cerebral hemispheres. Generally the right hemispheres receives sensations from, and controls movement of the left side of the body and vice versa. Everyone has a similar general pattern: bumps: gyri and grooves; sulci and fissures, used to separate portion of the brain into lobes.
