The new findings identify a potential contributor to microcephaly, a birth defect in which the head is underdeveloped and abnormally small.

Scientists have recorded blood oxygen levels in the hippocampus and provided experimental proof for why the area, commonly referred to as ‘the brain’s memory center’, is vulnerable to damage and degeneration, a precursor to Alzheimer’s disease.

Researchers have developed a new technique that allows microscopic fluorescence imaging at four times the depth limit imposed by light diffusion. Fluorescence microscopy is often used to image molecular and cellular details of the brain in animal model…

An innovative study uses the anesthetics propofol and isoflurane in humans to study the patterns of reemerging consciousness and cognitive function after anesthesia.

Researchers have found that normal exposure to light can drive the formation and growth of optic nerve tumors in mice — and maybe people — with a genetic predisposition. Such tumors can lead to vision loss.

A novel compound similar in structure to the psychedelic drug ibogaine, but lacking its toxic and hallucinogenic effects, has been found to rapidly reverse the effects of stress in mice. Researchers found that a single dose of tabernanthalog (TBG) can …

Alzheimer’s disease is the main cause of dementia and current therapeutic strategies cannot prevent, slow down or cure the pathology. The disease is characterized by memory loss, caused by the degeneration and death of neuronal cells in several regions…

Patients who suffer from REM sleep behavior disorder have altered blood flow in the brain, which can lead to a lack of oxygen in the brain tissue. In the long term, this may cause symptoms of Parkinson’s disease.

While we sleep, the brain produces particular activation patterns. When two of these patterns – slow oscillations and sleep spindles – gear into each other, previous experiences are reactivated. The stronger the reactivation, the clearer will be our re…

Scientists have discovered a new role for bile acids: they curb appetite by entering the brain. Their findings provide new insights into the signals and mechanisms by which satiety is controlled and may have implications for treating obesity.
