WebThe neurotransmitter diffuses across the synaptic cleft and binds to ligand-gated ion channels (channels opened by chemical transmitter) in the post-synaptic membrane, resulting in a localized depolarization (EPSP) or hyperpolarization (IPSP) of the post-synaptic neuron depending upon the type of transmitter, excitatory or inhibitory. WebNeuromodulators are substances that do not directly activate ion-channel receptors but that, acting together with neurotransmitters, enhance the excitatory or inhibitory responses of the receptors. It is often impossible to determine, in the presence of many substances, which are transmitters and which are modulators.… Read More

WebNeurotransmission occurs by transporting information across neurons by an electrical impulse called an action potential. When an action potential reaches the synapse between two neurons, the pre-synaptic neuron releases neurotransmitters to transport the chemical signal across the synapse by binding to receptors on the post-synaptic neuron.
