Synaptic cleft1
Neurotransmitters diffuse across the synaptic cleft and bind briefly to specific receptors on the adjoining neuron or effector cell. (msdmanuals.com)
Postsynaptic receptors1
The receptors then release the neurotransmitters, which are recycled back into the presynaptic terminal or broken down enzymatically, allowing postsynaptic receptors to receive new signals from the presynaptic neuron. (brainfacts.org)
Excitatory4
Domoic acid (DA) is structurally similar to the excitatory neurotransmitter glutamate. (medscape.com)

Neurotransmitters5
Neurons can also adjust the amount of chemical messengers (neurotransmitters) they release as well as the number of membrane proteins (receptors) that receive messages. (brainfacts.org)
Upon binding neurotransmitters, receptors unleash a cascade of molecular events that convert the message back into an electrical signal. (brainfacts.org)
This, in turn, activates several kinds of enzymes, some of which increase the number of synaptic receptors, making the synapse more sensitive to neurotransmitters. (brainfacts.org)
Neurotransmitters that are released bind to receptors on another neuron. (msdmanuals.com)
In such cases, the dendrites (a neuron's receiving branches) on the postsynaptic neurons release neurotransmitters that affect receptors on the presynaptic neurons. (msdmanuals.com)
