Does spike-time dependant plasticity occurs in dorsal horn neurons
... In the case of wind-up, presynaptic spikes from Aβ fibers cause a fast depolarization in the dorsal horn neurons. This depolarization cannot lead to any postsynaptic action potential in the dorsal horn, but up-regulates the NMDA receptors, which are located on the dorsal horn. Then, spikes from C fi ...
