WitrynaA bipolar neuron is a type of cell characterized by containing two processes: an axon and a dendrite. These types of neurons are less prevalent in the brain than multipolar neurons (they contain more than one dendrite), but more prevalent than unipolar neurons (they contain a single prolongation that acts as both an axon and a dendrite) jessica bassey amazon linkedinOften found in the retina, bipolar cells are crucial as they serve as both direct and indirect cell pathways. The specific location of the bipolar cells allow them to facilitate the passage of signals from where they start in the receptors to where they arrive at the amacrine and ganglion cells.
