Epsp-spike coupling

WebJan 5, 2001 · The results indicate that EPSPs are shaped by a complex interplay of several channel types depending on stimulus intensity and membrane potential, and the interaction between excitatory postsynaptic potentials (EPSPs) and voltage-gated channels. Expand View 1 excerpt, cites background Save Alert Background Synaptic Activity Is Sparse in … WebIt would appear that LC activation most frequently potentiates the coupling of the EPSP and population spike rather than potentiating the EPSP slope itself. Such enhanced population spike effects are also seen with frequency-induced LTP ( Bliss and Gardner-Medwin, 1973; Taube and Schwartzkroin, 1988 ).
