A study from the ‘90s repeatedly woke participants just as they dropped off to sleep, to ask them about their hypnagogic experiences: Only a minority included all the wacky wonders of normal dreams in terms of intricate plots and hallucinatory special effects. However, it’s probably best to think of this as your brain’s B-movie equivalent to a full-on REM (rapid eye movement) dream. As you slip out of consciousness, your brain puts on an instant dream show. This is likely the consequence of the dramatic spread of activity that was seen in this study across multiple sensory and emotional regions upon involuntary eye closure. What to make of all the neural shenanigans that occur when we lose the fight to stay awake? Previous research has described how, if you wake someone just after they’ve drifted off, they will often say they were experiencing strange, vivid feelings and sights - what’s often referred to as a hypnagogic state. This same combination of brain changes was not observed when participants were rested and chose to close their eyes at will. More surprising still, the researchers found micro-sleeps triggered extra joint activation of frontal and more rearward brain areas involved in paying attention. More surprising – since we usually think of sleep as a restful activity – the participants’ involuntary eye closures were also associated with a dramatic uptick in activity across multiple regions, including areas involved in processing sensory information, moving the body, and the emotions, including self-awareness and memory (conversely, other areas, such as the anterior cingulate cortex - sometimes nicknamed the “ oh shit circuit” for its role in error monitoring - showed a reduction in activity). As their wakefulness slipped away, the participants were shutting down their connection to the outside world. It acts like a gateway, filtering the sensory information that’s sent to higher brain areas for further processing. When participants’ eyelids fell shut involuntarily and momentarily - some researchers call this a “micro-sleep” - one neural hallmark was a reduction in activation in the thalamus, a structure beneath the cortex that is often described as the brain’s relay station. To make sure that any observed neural activity wasn’t simply a consequence of the act of closing the eyes, a comparison scanning session was performed in which the same participants were well-rested and simply instructed to close their eyes briefly at intermittent intervals. The researchers looked specifically at the patterns of activity in the participants’ brains in those moments that their eyes fell involuntarily shut. Kudos to Suumit for agreeing to sit in the hot seat here.Needless to say, the participants’ eyes frequently drifted shut, and whenever that happened they were prompted by recorded messages to keep their eyes open. I suppose that's where I get some tolerance for his BS. He's a good friend, always helps if you call. Where people could ask hard questions, share their honest opinions while being truly anonymous.įull disclosure, Suumit and I are friends. ![]() Virtually every tech company is laying people off, high time a CEO took some questions from everyone in a public forum. Honesty delivered kindly would be ideal.Īnyhow, I think this is a conversation which has been due for a lot of us. But in an ecosystem where silent layoffs are the trend, I'd take Suumit's unsavoury honesty over keeping hush. ![]() The insensitive Support team firing announcement, calling an enquiring customer the C word - I think Suumit could do better. ![]() ![]() I'm not a fan of his crass communication. Suumit, as you know, is the CEO of Dukaan® amongst other things. It'll be anonymous, honest and knowing Suumit, likely to be v v entertaining. We're hosting our first #AnonAMA with Suumit Shah on Together.
