... and responds to it. To illustrate, using brain mapping technology such as EEG a person in one room has their brain monitored while a person in a distant room has their brain randomly stimulated, usually through visual stimulation, such as a ...
... These effects seem to be a function of frontal brain areas.[33] Others have argued that the capacity of working memory is better characterized as the ability to mentally form relations between elements, or to grasp relations in given informatio...
... contain all the colors that the human eyes and brain can distinguish. Unsaturated colors such as pink, or purple variations such as magenta, are absent, for example, because they can only be made by a mix of multiple wavelengths. Visible wavele...
... and the number of distinct perceptions the brain can analyze at any one time. Despite functional limitations, human consciousness is seamless, meaning that each perception and behavior flows smoothly from one to the next. When consciousness is...
... procedures were used. As in rat brain, d-LSD was the most potent displacer of 3H-ketanserin specific binding with a Ki of 0.9 nM. The phenylisopropylamine DOI also displayed high affinity (Ki of 6 nM). Stereospecific interactions we...

... tell us something fundamental about how our brains are wired up. And it seems that they can. Geometric hallucinations were first studied systematically in the 1920s by the German-American psychologist Heinrich Klüver. Klüver's interest in ...
Vivid dreams, hallucinations, psychosis and REM sleep in Guillain-Barré syndrome
We conducted a prospective controlled study of the clinical and biological determinants of the mental status abnormalities in 139 patients with Guillain-Barré syndrome (GBS) and 55 patients without GBS placed in the intensive care unit (ICU controls...

Psychedelic Drugs Reconsidered

Sleep, dreams, and memory consolidation: the role of the stress hormone cortisol
... which is known to exert influence on many of the brain systems involved in memory. The concentration of cortisol escalates over the course of the night's sleep, in ways that we propose can help explain the changing nature of dreams across the sleep ...
... saw sleep as a passive condition where the brain is isolated from the other parts of the body. Alcmaeon claimed that sleep was caused by the blood receding from the blood vessels in the skin to the interior parts of the body. Aristotle suggest...
Sleep and General Anesthesia as Altered States of Consciousness

The neuropsychology of REM sleep dreaming
RECENT PET imaging and brain lesion studies in humans are integrated with new basic research findings at the cellular level in animals to explain how the formal cognitive features of dreaming may be the combined product of a shift in neuromodulatory ...
