Neuron doctrine
Golgi stain
stain used to study brain cells that specifically takes neurons but not all neurons take it
Nissl stain
stain used to study brain anatomy that stains whole cells and is not limited to neurons
neurons
make up 10% of cells in the brain and function in computation
glia
schwann cell
oligodendrocyte
astrocyte
microglia
synapse
synaptic vesicles

depolarization
cathodes
attract cations (-) are positive
anodes
attract cations (+) are negative
