Receptors brain
The structures of receptors are very diverse and include the following major categories, among others: • Type 1: Ligand-gated ion channels (ionotropic receptors) – These receptors are typically the targets of fast neurotransmitters such as acetylcholine (nicotinic) and GABA; activation of these receptors results in changes in ion movement ac… WebbNicotinic receptors are ligand-gated ion channels widely distributed in the brain. Nicotinic receptors influence synaptic plasticity, motor function, and behavior. Nicotinic receptor alterations are implicated in multiple neuropsychiatric disorders. Nicotinic receptors are therapeutic targets for multiple neuropsychiatric disorders.
