Glutamate receptor Glutamate receptor Glutamate receptors are synaptic and non synaptic receptors located primarily on the membranes of neuronal and glial cells. Glutamate (the conjugate base of glutamic acid) is abundant in the human body, but particularly in the nervous system and especially prominent in the human brain where it is the body's most prominent neurotransmitter, the brain's main excitatory neurotransmitter, and also the precursor for GABA, the brain's main inhibitory neurotransmitter. Glutamate receptors are responsible for the glutamate-mediated postsynaptic excitation of neural cells, and are important for neural communication, memory formation, learning, and regulation. Glutamate receptors are implicated in a number
Radial glial cell astrocytes, they have also been called "specialized astrocytes." Bergmann glia have multiple radial processes that extend across the molecular layer of the cerebral cortex and terminate at the pial surface as a bulbous endfoot. Bergmann glial cells assist with the migration of granule cells, guiding the small neurons from the external granular layer to the internal granular layer of the cerebral cortex along their extensive radial processes. Besides their role in early development of the cerebellum, Bergmann glia are also required for synaptic pruning. Following Purkinje cell death induced by CNS injury, Bergmann glia undergo extensive proliferative changes so as
