Manganese released into the synaptic cleft may influence synaptic neurotransmission. Dietary manganese deficiency, which may enhance susceptibility to epileptic functions, appears to affect manganese homeostasis in the brain, probably followed by alteration of neural activity. On the other hand, manganese ...
Once the terminal button is depolarized, it releases a neurotransmitter into the synaptic cleft. The neurotransmitter binds to its receptors on the postsynaptic membrane of the target cell, causing its response either in terms of stimulation or inhibition. Action potentials are propagated faster through...
A portion of the presynaptic membrane that faces the postsynaptic density across the synaptic cleft. It constitutes the site of synaptic vesicle clustering, docking and neurotransmitter release. Heteroreceptors Presynaptic receptors that are activated by neurotransmitters released from nerve terminals other th...

Mediates somatodendritic dopamine release in hippocampal neurons, likely as part of a regulated secretory pathway that integrates retrograde synaptic signals (By similarity). Acts as a primary transporter for striatal dopamine loading ensuring impulse-dependent release of dopamine at the synaptic cleft (By...
(B) The neuromuscular synapse is a complex anatomical structure consisting of a presynaptic neural fiber, the synaptic cleft, and a postsynaptic muscle fiber. An incoming action potential along the neural fiber always produces an action potential on the muscle fiber: This action is called obli...
Neural signalling relies on action potentials (APs) that travel along the axon. The AP, initiated by the presynaptic neuron, triggers neurotransmitter release across the synaptic cleft. These neurotransmitters bind to receptors on the postsynaptic neuron, influencing its excitability. Excitatory neurotransm...
Describe the events that take place when the action potential spreads throughout the axon terminal leading up to the release of neurotransmitters into the synaptic cleft.
