Document Summary

Measure: allow you to graph normative stale of brain, get better understanding on how brain work, easy on human subject. Manipulation: get result fast quick precise with fmri just use correlational. Model: cheap, non-invasive good for animal activist control, not lot of control with an animal. You want to determine what the constitute elements of the brain are. The amount of light transmitted across the tissue is almost constant. The launch of neuroscience: the discovery of the golgi method. Silver staining method allowed for visualization of neurons and their processes (the stain blocks the light which contrasts) Membrane is more porous to the movement of ions. Block the flow of sodium ions into the cell (ttx blocks the sodium channel)
