👉 In neurobiology and neuroscience, a nonexcitatory (or inhibitory) neuron is one that does not actively transmit information or conduct electrical signals. This means that it does not release neurotransmitters (such as acetylcholine) into its dendrites to facilitate the transmission of signals. Instead, its axon carries these signals through the cell membrane and into other neurons. Nonexcitatory neurons are often found in the central nervous system (CNS), where they play a crucial role in
