From exams to interviews, research reveals what actually happens inside the head when the mind goes blank

Scientists are shedding light on moments when the mind suddenly goes blank, revealing it as a distinct mental state rather than mere distraction. A study by Sorbonne Universit researchers, published in PNAS, found that during such episodes the brain briefly resembles a light sleep state despite wakefulness. Tracking 62 adults showed reduced brain connectivity, poorer performance, and diminished awareness, challenging assumptions that being awake always means being consciously engaged.
