Document Summary

Dorsal stream: "how and where system" --> how to localize ourselves in response to visio. Ventral stream: "what system" --> vision gets tied to object naming. Damage to the prefrontal cortex area leads to: The pyramidal cells are found in extremely dense areas, meaning there is lots of info processing vision ssing arou. The pyramidal cells are found in extremely dense areas, meaning there is lots of info processing occurring there. In the cerebellum, there are lots of input areas, taking info in and then processing it. Motor neurons have lots of myelin so they can communicate quickly, the white fatty layer arou the cell so it can send messages faster. Sensory motor neurons connect to a non-neuron, and sensory neurones go to receptor neuron. A cell that accumulates and transmits electrochemical activity in the nervous system. Each neuron has a threshold for how much info it can fire or not fire.
