Even more fascinating, the intensity of this glow changes based on brain activity. These surprising results were achieved through highly controlled experiments conducted in complete darkness using ultra-sensitive equipment capable of detecting even the faintest light emissions.<\/p>\n<article class=\"text-token-text-primary w-full\" dir=\"auto\" data-testid=\"conversation-turn-4\" data-scroll-anchor=\"true\">\n<div class=\"text-base my-auto mx-auto py-5 [--thread-content-margin:--spacing(4)] @[37rem]:[--thread-content-margin:--spacing(6)] @[72rem]:[--thread-content-margin:--spacing(16)] px-(--thread-content-margin)\">\n<div class=\"[--thread-content-max-width:32rem] @[34rem]:[--thread-content-max-width:40rem] @[64rem]:[--thread-content-max-width:48rem] mx-auto flex max-w-(--thread-content-max-width) flex-1 text-base gap-4 md:gap-5 lg:gap-6 group\/turn-messages focus-visible:outline-hidden\" tabindex=\"-1\">\n<div class=\"group\/conversation-turn relative flex w-full min-w-0 flex-col agent-turn\">\n<div class=\"relative flex-col gap-1 md:gap-3\">\n<div class=\"flex max-w-full flex-col grow\">\n<div class=\"min-h-8 text-message relative flex w-full flex-col items-end gap-2 text-start break-words whitespace-normal [.text-message+&amp;]:mt-5\" dir=\"auto\" data-message-author-role=\"assistant\" data-message-id=\"40e7e161-0e67-4128-b7c4-ab947bbf5efa\" data-message-model-slug=\"gpt-4o\">\n<div class=\"flex w-full flex-col gap-1 empty:hidden first:pt-[3px]\">\n<div class=\"markdown prose dark:prose-invert w-full break-words light\">\n<h3 class=\"ai-optimize-14\" data-start=\"23\" data-end=\"93\">Brain&#8217;s Hidden Light Signals May Revolutionize Mental Health Diagnosis<\/h3>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"flex min-h-[46px] justify-start\"><\/div>\n<\/div>\n<div class=\"absolute\">\n<div class=\"flex items-center justify-center\">The study observed participants during rest and while performing auditory tasks, and a clear difference in light patterns was found between the two states.
