Medium spiny neurons have two primary phenotypes (characteristic types): D1-type MSNs of the direct pathway and D2-type MSNs of the indirect pathway. [ 2 ] [ 3 ] [ 4 ] Most striatal MSNs contain only D1-type or D2-type dopamine receptors , but a subpopulation of MSNs exhibit both phenotypes.
English: Complete neuron cell diagram. Neurons (also known as neurones and nerve cells) are electrically excitable cells in the nervous system that process and transmit information. In vertebrate animals, neurons are the core components of the brain, spinal cord and peripheral nerves.
Dendritic spines serve as a storage site for synaptic strength and help transmit electrical signals to the neuron's cell body. Most spines have a bulbous head (the spine head), and a thin neck that connects the head of the spine to the shaft of the dendrite. The dendrites of a single neuron can contain hundreds to thousands of spines.
The D1-type medium spiny neurons mediate reward-related cognitive processes, [5] [35] [36] whereas the D2-type medium spiny neurons mediate aversion-related cognition. [6] The neurons in the core, as compared to the neurons in the shell, have an increased density of dendritic spines, branch segments, and terminal segments.
Spinal neurons are specialized nerve cells located within the spinal cord. [1] They are a crucial component of the central nervous system.These neurons play vital roles in transmitting and processing information between the brain and the rest of the body.

The granule cell has a characteristic cone-shaped tree of spiny apical dendrites. The dendrite branches project throughout the entire molecular layer, and the furthest tips of the dendritic tree end at the hippocampal fissure or at the ventricular surface. [4] The granule cells are tightly packed in the granular cell layer of the dentate gyrus.
