Document Summary

Concept of localization of function arose in the 19th century. A proponent of phrenology belief that personal characteristics were related to bumps on the head. Gets credit for supporting localization but not correct. Attributed to loss of speech production to a specific area of the brain. A man could only say hand damage to broca"s area. The location of a memory in the brain. Described memories as a distribution of cell networks. Memory is a pattern of activity across multiple cells. Multiple neurons supporting and representing a memory. Neurons form a structural physical connection to form memory. No structural connection memory physical connection. Brain cells (neurons) are independent functional units. Distribution of charges across the neuron"s cell membrane. At rest, the inside is more negative and the outside is more positive. Neurons can open channels in its membrane. When channels open, the inside of the cell becomes more like the outside. Helps transmits/carry the signal toward the next cell.
