Interneurons meaning
Interneurons (also called internuncial neurons, relay neurons, association neurons, connector neurons, intermediate neurons or local circuit neurons) are neurons that connect to brain regions, i.e. not direct motor neurons or sensory neurons. Interneurons are the central nodes of neural circuits, enabling … See more Approximately 20–30% of the neurons in the neocortex are interneurons, while the remaining neurons are pyramidal neurons. Investigations into the molecular diversity of neurons is impeded by the inability to isolate cell … See more Interneurons in the CNS are primarily inhibitory, and use the neurotransmitter GABA or glycine. However, excitatory interneurons using See more • Relay (disambiguation) See more Web• Most reflex arcs are polysynaptic, meaning multiple interneurons (also called relay neurons) interface between the sensory and motor neurons in the reflex pathway. • The spinal cord provides the synapse for the reflex arc, even though the reflex arc is bypassing the brain, the brain is still aware of the occurrence.
