WebMar 6, 2024 · The neurotransmitter remains in the synaptic cleft for a short time. Then it is either returned to the presynaptic neuron through the process of reuptake, metabolized by enzymes, or bound to the receptor. When a neurotransmitter binds to a postsynaptic neuron, it can either excite it or inhibit it. WebNeurotransmitters are electrochemical messengers that transmit nerve impulses across the synaptic gap during the process of synaptic transmission. Some neurotransmitters are excitatory and some are inhibitory. Excitatory neurotransmitters (e.g. noradrenaline) make the post synaptic cell more likely to fire, whereas inhibitory neurotransmitters (e.g. GABA) … chumi gyatse monastryWebAt a synapse, one neuron sends a message to a target neuron—another cell. Most synapses are chemical; these synapses communicate using chemical messengers. Other synapses are electrical; in these synapses, ions flow directly between cells.
