Several theories claim that dreaming is a random by-product of REM sleep physiology and
that it does not serve any natural function. Phenomenal dream content, however, is not as …

Even modest sleep restriction, especially the loss of sleep slow wave activity (SWA), is
invariably associated with slower electroencephalogram (EEG) activity during wake, the …

Noise has both auditory and extra-auditory effects. Some of the most deleterious extra-
auditory effects of noise are those leading to sleep disturbances. These disturbances seem …

Lucid dreaming provides a test case for theories of dreaming. For example, whether or not
“loss of self-reflective awareness” is characteristic of dreaming, it is not necessary to …

The most important recent work on the neurobiology of sleep has focused on the precise
cellular and biochemical mechanisms of rapid eye movement sleep mediation. Direct and …

There are obvious flaws in REM sleep suppression paradigms that do not allow any
conclusion to be drawn either pro or contra the REM sleep-memory hypothesis. However …

We investigated the temporal relationship between hippocampal theta waves and ponto–
geniculo–occipital waves (PGO) during rapid eye movement sleep (REM sleep) in cats. In …

The most challenging objections to the Threat Simulation Theory (TST) of the function of
dreaming include such issues as whether the competing Random Activation Theory can …

In an attempt to induce eye movements (EMs) in non-rapid eye movement sleep, light and
sound stimuli were presented to human subjects (at below-waking threshold) during stage 2 …

Waves similar to ponto-geniculo-occipital (PGO) waves occurring spontaneously in the
lateral geniculate body (LGB) pons, and occipital cortex during rapid eye movement (REM) …
