Einstein"s brain: wider parietal region, distinct sylvian fissure. Sylvian fissure: groove sperating frontal lobe from temporal lobe. Witelson studied his brain said that he was probably smart for those reasons, and inferior parietal lobules. Neurons: cells in nervous system that receive, integrate, and transmit info. Soma or cell body contains nucleus and much of chemical machinery common to most cells. Dendritic trees composed of dendrites specialized to receive info. Receive info from thousands of neurons and need extensive dendritic trees. Info dendrite soma axon terminal buttons synapse dendrite of other cell . Axon: long, thin fibre that transmits signals away from soma to other neurons, muscles or glands. Long (maybe metres long), branch off to communicate with number of other cells. Myelin sheath: insulating material derived from glial cells, encases some axon, speeds up transmission of signals (multiple sclerosis degeneration of myelin sheath) Synapse: point where neurons interconnect, info transmitted from one neuron to another.
