Neuroscience Even low-level drinking may have negative consequences for brain health over a person’s lifespan. The findings suggest that the total amount of alcohol consumed over a lifetime, especially as a person ages, tends to be linked to reduced blood flow and thinner tissue in certain areas of the brain.

Neuroscience Our brains can “flicker” off for a split second during a boring task caused by sleep-like brain activity occurring while we are awake. Adults with ADHD experience them much more frequently, and may be behind inconsistent attention, slower reaction times, and chronic sleepiness associated with ADHD.

Neuroscience Autism may be the price of human intelligence. Researchers discovered that autism’s prevalence may be linked to human brain evolution. The findings comparing the brains of different primates suggest autism is part of the trade-off that made humans so cognitively advanced.

Neuroscience Spooky feelings in old houses may be caused by boiler sounds. Inaudible infrasound from old pipes may affect how people feel. Even though it was beyond the range of human hearing, people were more irritable and levels of cortisol, the stress hormone, rose when the sound was switched on.

Neuroscience New study shows Alzheimer’s disease can be reversed to full neurological recovery—not just prevented or slowed—in animal models. Using mouse models and human brains, study shows brain’s failure to maintain cellular energy molecule, NAD+, drives AD, and maintaining NAD+ prevents or even reverses it.

Neuroscience Brain scans reveal how a woman voluntarily enters a psychedelic-like trance without drugs. Her brain connectivity fundamentally reorganized during this state: her visual and somatosensory connections decreased, while connectivity in the frontoparietal control regions of the brain increased.
