32 We investigated the ionic mechanisms that allow dynamic regulation of action potential 33 (AP) amplitude as a means of regulating energetic costs of AP signaling. Weakly electric fish 34 generate an electric organ discharge (EOD) by summing the APs of their electric organ cells 35 (electrocytes). Some electric fish increase AP amplitude during active periods or social 36 interactions and dec...

18 Thalamic paraventricular nucleus (PVT) neurons exhibit a post-burst apamin-resistant 19 slow afterhyperpolarization (sAHP) that is unique to midline thalamus, displays activity 20 dependence and is abolished in tetrodotoxin. Analysis of the underlying sIAHP confirmed a 21 requirement for Ca influx with contributions from P/Q-, N-, Land R subtype channels, a 22 reversal potential near EK and ...
