Gamma band activity in the developing parafascicular nucleus ( Pf ) 1
23 The parafascicular nucleus (Pf) receives cholinergic input from the pedunculopontine 24 nucleus, part of the reticular activating system involved in waking and REM sleep, and sends 25 projections to the cortex. We tested the hypothesis that Pf neurons fire maximally at gamma 26 band frequency (30-90 Hz), that this mechanism involves high threshold voltage-dependent 27 P/Qand N-type calcium c...

The parafascicular nucleus (Pf) receives cholinergic input from the pedunculopontine nucleus, part of the reticular activating system involved in waking and rapid eye movement (REM) sleep, and sends projections to the cortex. We tested the hypothesis that Pf neurons fire maximally at gamma band frequency (30-90 Hz), that this mechanism involves high-threshold voltage-dependent P/Q- and N-type c...
متن کاملHigh-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 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...
متن کامل1 Gamma band unit activity and population responses 1 in the pedunculopontine nucleus ( PPN ) 2
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...
