Pre and postsynaptic neuron
WebApr 12, 2024 · When environmental disturbance happens, the presynaptic neuron senses the changes of neural activity, and releases anterograde signals to the postsynaptic neuron to change the synaptic strength and adapt to the environment. However, the mechanism of how presynaptic neurons trigger anterograde signals at the inhibitory synapses remains … WebThe neuron transmitting the signal is called the presynaptic neuron, and the neuron receiving the signal is called the postsynaptic neuron. Note that these designations are relative to a particular synapse—most neurons are both presynaptic and postsynaptic. ... prolonged decrease in synaptic coupling between a pre- and postsynaptic cell
