Frequency-dependent potentiation of voltage-activated responses only in the intact neurohypophysis of the rat.
Pflugers Arch. 2005 May;450(2):96-110. doi: 10.1007/s00424-004-1376-0. Epub 2005 Jan 15.

We conclude that voltage-gated channels underlie this potentiation, which is due to interstitial calcium and potassium homeostasis changes induced by action potential activity and occurs only in the intact NH. A model is proposed for the participation of calcium and potass …

We demonstrate that the oscillations are mediated by recruiting negative feedback by protein kinase C, and we map the site responsible for the effect of protein kinase C to Thr339 in the C terminus of P2Y1R. We propose that frequency-dependent changes in ATP-mediate …

First, we show that different models have different frequency-dependent response properties, yielding large differences in excitability. Then, we investigate the responsiveness of these models to a single afferent inhibitory/excitatory spike and calibrate the total …
