Blood–brain Barrier Turns More Permeable In Sleep Apnea

Obstructive sleep apnea contributes to a breakdown of the blood–brain barrier, which plays an important role in protecting brain tissue, UCLA researchers report. The finding could lead to new approaches for treating obstructive sleep apnea, which affects an estimated 22 million American adults. The disorder causes frequent interruptions in breathing during sleep because the airways […]

Noradrenergic Plasticity: How Sudden Sounds Form Long Term Memories

The mechanism by which even brief exposure to sudden sounds or mild trauma can form permanent, long-term brain connections, or memories, in a specific region of the brain has been revealed by researchers at NYU Langone Medical Center. The research team, working with rats, also says it was able to chemically stimulate those biological pathways […]

Visual Brain Used By The Blind To Learn Language

By early childhood, the sight regions of a blind person’s brain respond to sound, especially spoken language, new research shows. The results suggest a young, developing brain has a striking capacity for functional adaptation. Johns Hopkins University cognitive neuroscientist Marina Bedny, who conducted the research while at Massachusetts Institute of Technology, says: “The traditional view […]
