Neuroscience Stains: Nissl and Golgi Stain

The neuron doctrine is the idea that the nervous system is made up of individual neurons. It was discovered by Cajal.

Neurons can be classified as unipolar (one neurite), bipolar (two neurites), or multipolar (three or more neurites).

Spiny neurons have dendrites with spines, while aspinous neurons lack dendritic spines.
