High-threshold Ca2+ channels behind gamma band activity in the pedunculopontine nucleus (PPN)
The pedunculopontine nucleus (PPN) is part of the Reticular Activating System, and active during waking and REM sleep. Previous results showed that all PPN cells plateau at gamma frequencies and intrinsic membrane oscillations in PPN neurons are mediated by high-threshold N- and P/Q-type Ca(2+) channels. The present study was designed to determine whether some PPN cells have only N-, only P/Q-,...
متن کاملPedunculopontine Gamma Band Activity and Development
This review highlights the most important discovery in the reticular activating system in the last 10 years, the manifestation of gamma band activity in cells of the reticular activating system (RAS), especially in the pedunculopontine nucleus, which is in charge of waking and rapid eye movement (REM) sleep. The identification of different cell groups manifesting P/Q-type Ca(2+) channels that c...
متن کاملIntracellular mechanisms modulating gamma band activity in the pedunculopontine nucleus (PPN)
The pedunculopontine nucleus is a part of the reticular activating system, and is active during waking and REM sleep. Previous results showed that all PPN cells tested fired maximally at gamma frequencies when depolarized. This intrinsic membrane property was shown to be mediated by high-threshold N- and P/Q-type Ca(2+) channels. Recent studies show that the PPN contains three independent popul...

27 The pedunculopontine nucleus (PPN) is involved in the activated states of waking and 28 paradoxical sleep, forming part of the reticular activating system (RAS). The studies described 29 tested the hypothesis that single unit and/or population responses of PPN neurons are capable 30 of generating gamma band frequency activity. Whole-cell patch clamp recordings (immersion 31 chamber) and popu...
