Postsynaptic Signal-Transduction Mechanisms Physiological DA transmission maintains a certain level of sensitivity in postsynaptic neurons, and the absence of DA causes postsynaptic receptors to become supersensitive.
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. There are two types of synapses: chemical and electrical. Chemical Synapse
