An international study reveals that "mind blanking" is not a mental failure, but rather a complex and frequent psychological state that could help better understand the limits of consciousness.
It’s a sensation most people have experienced: that moment when thoughts seem to vanish without warning. This experience, known as mind blanking or “going blank,” is more common than we usually admit and, far from being a mental failure, is beginning to be recognized as a distinct and complex psychological state.
A recent study published in the journal Trends in Cognitive Sciences, conducted by an international team of neuroscientists and philosophers, gathered evidence from over 80 investigations—including their own work—to understand what truly happens in the brain during these mental blanks. The first revelation was that going blank is not an exceptional event: on average, people experience it between 5% and 20% of their waking hours. It is more frequent during moments of fatigue, prolonged or boring tasks, and can intensify in individuals with conditions such as ADHD or anxiety disorders.
Although the sensation may seem like a total pause, researchers found that the brain does not “shut down” during these moments, but rather shifts its mode of operation. Studies using electroencephalograms and magnetic resonance imaging show that during these episodes, the complexity of neural activity decreases, heart rate drops, pupils contract, and brain waves similar to those of sleep appear. This suggests that certain areas of the brain may enter a “local sleep” state while the rest of the body remains awake. In some cases, there is also a deactivation of areas related to language, memory, and action control—such as Broca’s area, the hippocampus, and the supplementary motor cortex—especially when people consciously try to “empty their minds.”
The authors propose that the phenomenon may be linked to extreme variations in levels of brain activation. Both overstimulation and understimulation could temporarily affect the functioning of key systems like attention, memory, or language, creating these moments of apparent “nothingness.” This could explain why going blank is more common after a poor night’s sleep, in stressful situations, or even during practices like meditation.
Beyond its clinical implications, going blank raises a fundamental question about consciousness itself: is it possible to be awake without having thoughts? The researchers argue that this phenomenon deserves to be studied as an independent mental state, distinct from sleep, distraction, or mind-wandering. Recognizing it as such may help us better understand the boundaries and nuances of conscious experience.
So the next time you find your mind blank, consider that your brain may be operating in a way science is only beginning to understand. These mental silences could be more than mere lapses—they might be key moments in the intricate dance of the mind.
