WebAgonists mimic neurotransmitter effects, whereas antagonists block neurotransmitter effects. Muscimol, a component of some mushrooms, is an agonist for the ionotropic GABA receptor. Bicuculine, a component of some plants, is an antagonist to this receptor and blocks the action of GABA. WebNeurotransmitters diffuse across the synaptic cleft and bind briefly to specific receptors on the adjoining neuron or effector cell. Depending on the receptor, the response may be excitatory or inhibitory. Usually, neurons do not touch each other; instead, they communicate through the transmission of neurotransmitters across the synapses.
