Document Summary

Lecture 1 and 2 - intro to electrical circuits. Friday noon in gould 601 --> dr. nighorn. Unipolar: have a single process emanating from the cell. Bipolar: have two types of processes that are functionally-specific. Dendrite receives electrical signal and axon transmits signal to other cells. Pseudo-unipolar: variants of bipolar cells that carry somatosensory info to spinal cord. There are two segments that both function as axons; one extends to peripheral skin or muscle and the other to the spinal cord. Multipolar: have a single axon and many dendrites (most common type of neuronal cell). Pyramidal cells: found in hippocampus and throughout cerebral cortex. Purkinje cells: found in cerebellum and characterized by a rich dendritic tree. Potential difference that allows one to do electrical work by measuring electrical potential (difference) Is measured by how many ions go through the membrane. It"s how hard or easy ions can move across the membrane.
