postsynaptic neuron

postsynaptic neuron

a neuron to the cell body or dendrite of which an electrical impulse is transmitted across a synaptic cleft by the release of a chemical neurotransmitter from the axon terminal of a presynaptic neuron.

The appropriate machinery for synthesizing and releasing the retrograde messenger must be located in the postsynaptic neuron.
Not all neurotransmitter released by the presynaptic neuron is bound by the postsynaptic neuron.
The released neurotransmitter binds to postsynaptic receptors, leading to a response in the postsynaptic neuron.
1993), "cellular research has shown that the introduction of dopamine into synapses immediately after a postsynaptic neuron has been activated by a presynaptic neuron produces long-lasting changes in synaptic efficacies.
A third variable modulating dopamine's effect is the number of dopamine receptors on the postsynaptic neuron.
For a cortex-like network to operate properly, a regulation mechanism that keeps the activity level within certain bounds should be assumed (coactivation of a pre- and postsynaptic neuron leads to synaptic strengthening).
In biology, there are processes that lead to internal neuronal changes in case of indirectly activation of the transfer channels of the postsynaptic neuron (see [15] or [16]).
The glutamate then interacts with receptors on the surface of the postsynaptic neuron, thereby initiating changes in that neuron that culminate in the generation of a new nerve signal in that cell.
This enhanced response persists indefinitely and is associated with changes in the density and the length of the dendrite of the postsynaptic neuron (Kolb & Whishaw, 2003).
