Functional neuroimaging using positron emission tomography has recently yielded original
data on the functional neuroanatomy of human sleep. This paper attempts to describe the …

Several areas in the brainstem and forebrain are important for the modulation and
expression of the sleep/wake cycle. Even if the first observations of biochemical events in …

It is known that acetylcholine can stimulate activation and promote plasticity in the cerebral
cortex, yet it is not known how the cholinergic basal forebrain neurons, which release …

The distribution of regional cerebral blood flow (rCBF) was estimated during sleep and
wakefulness by using H215O positron emission tomography (PET) and statistical parametric …

1. The electroresponsive properties of neurons from layer II of the rat medial entorhinal
cortex (MEC) were studied by intracellular recording under current clamp in an in vitro brain …

The basal forebrain constitutes the ventral extra-thalamic relay from the brainstem activating
system to the cerebral cortex. Cholinergic neurons form an important contingent of this relay …

The histaminergic system is exclusively localized within the posterior hypothalamus with
projection to almost all the major regions of the central nervous system. Strong and …

The extrathalamic relay from the brainstem reticular formation to the cerebral cortex in the
basal forebrain has been thought to be constituted predominantly, if not exclusively, by …

The medial septum‐diagonal band complex (MSDB) contains cholinergic and non‐
cholinergic neurons known to play key roles in learning and memory processing, and in the …

The occurrence of high-frequency γ activity (30–60 Hz) and its relationship to other
frequency band activities were examined by spectral analysis of the electroencephalogram …
