Rapid eye movement sleep decreases between 10 and 30 days postnatally in the rat. The
pedunculopontine nucleus is known to modulate waking and rapid eye movement sleep …

Since the early'60s, injections of a broad-spectrum muscarinic cholinergic agonist,
carbachol, into the medial pontine reticular formation (mPRF) of cats have been extensively …

1. The present study was performed to examine the hypothesis that the caudolateral
peribrachial area (C-PBL) may be directly involved in shifting the brain from the …

Results reported here confirm and extend those of early retrograde transport studies of the
brainstem in the rat and cat. This study demonstrates substantial and multiple afferent …

Paradoxical sleep (PS) is composed of several characteristic “tonic” and “phasic” events. In
this paper, it was shown that each of these “PS-subsystems” might be generated by distinct …

USING microiontophoresis on unanesthetized head-restrained cats, we have found two
distinct groups of neurones exhibiting tonic discharge specific to paradoxical sleep (PS)(PS …

It is well accepted that populations of neurons responsible for the onset and maintenance of
paradoxical sleep (PS) are restricted to the brainstem. To localize the structures involved …

The interaction of cholinergic and catecholaminergic mechanisms in the mesopontine
region has been hypothesized as being critical for the generation and maintenance of active …

Adrenergic input to the medial pontine reticular formation (mPRF) has been postulated to
play an important role in behavioral state control. Previous work has shown that direct …

Recent studies have shown that in the pedunculopontine tegmental nucleus (PPT),
increased neuronal activity and kainate receptor-mediated activation of intracellular protein …
