Intracellular 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 کاملevent - related gamma band activity in the lateral
44 Although the thalamus is an important module in ‘pain networks’, there are few studies of 45 the effect of experimental pain upon thalamic oscillations. We have now examined the 46 hypothesis that during a series of painful cutaneous laser stimuli thalamic signals will show 47 stimulus-related gamma band spectral activity, which is modulated by attention to versus 48 distraction from the pai...
متن کاملGamma 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...
متن کاملGamma Band Activity in the Reticular Activating System
This review considers recent evidence showing that cells in three regions of the reticular activating system (RAS) exhibit gamma band activity, and describes the mechanisms behind such manifestation. Specifically, we discuss how cells in the mesopontine pedunculopontine nucleus (PPN), intralaminar parafascicular nucleus (Pf), and pontine subcoeruleus nucleus dorsalis (SubCD) all fire in the bet...
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...
