New research indicates that dreaming during REM sleep may consume significant brain energy, with neuronal energy levels dropping despite an increase in the brain's fuel supply.
Caffeine can reduce the restorative quality of sleep by decreasing slow-wave brain activity, even if it doesn't prevent someone from falling asleep or staying asleep for a full night.
Scientists developed a needle-thin brain implant that can record neural activity, deliver drugs, and stimulate multiple brain regions simultaneously, offering a precise research tool and potential treatment for neurological disorders.
A new study reveals that the 3D organization of DNA is disrupted in brain cells affected by Alzheimer's disease, altering gene activity.
A new study found that slow breathing with a prolonged exhale can make people more willing to take risks by changing heart activity and increasing the brain’s sensitivity to rewards.
A new study reveals that prolonged exhales during slow breathing can make people more willing to take risks by changing heart activity and increasing the brain's sensitivity to rewards.
New research reveals that schizophrenia is linked to a widespread, organized loss of brain synapses, particularly in the left hemisphere, following the brain's unique molecular and connectivity architecture.
A stress hormone called CRH may help the brain repair itself after injury and influence normal brain development by regulating myelin-producing cells.
