This Is What Happens Inside Your Brain When It Suddenly Goes Blank, According To A New Study

You know that strange moment when your mind suddenly feels completely empty, and you have no clue where your thoughts just went? It turns out there’s now a scientific explanation for what might be happening when that occurs, and it's weirder than you might expect.

The phrase “my mind has gone blank” is something most of us have heard and probably even said ourselves more than once. It’s one of those universally relatable moments that can happen during a conversation, while reading, or even in the middle of doing something important. For a long time, it seemed like just one of those things that happened without explanation.

But now, a new study has offered some surprising insight into what might actually be going on in the brain during these mental blackouts.

Researchers have found that this “mind blanking” isn't the same for everyone. Some people experience it more frequently, while others report a completely different version of it. The fact that we're only now beginning to understand the mechanics of it makes it all the more fascinating.

Athena Demertzi, the lead author of the study, explained that their goal was to "better understand mind blanking" by diving deep into existing research.

To do this, Demertzi and her team analyzed 80 relevant research articles, including some of their own studies where participants had their brain activity recorded while they reported “thinking of nothing.”

Their work is helping to uncover the hidden rhythms of the brain during these oddly empty moments—moments we’ve all experienced but never really understood.

Demertzi and her colleagues from France, Australia, and Belgium set out to explore the true nature of consciousness, and their in-depth research may bring us closer to understanding it.

After reviewing 80 research articles, the team discovered that, on average, people experience mind blanking about five to twenty percent of the time. They also found that the experience varies significantly from person to person.

For instance, individuals with neurodevelopmental disorders like ADHD may blank more frequently.

Some people may also experience both “blanking” and “mind wandering,” which, according to researchers, are two distinct mental states with different internal sensations. Blanking can happen during moments of sustained focus, after sleep deprivation, or while engaging in physically demanding activities like intense workouts.

In other cases, it may be linked to neurological or psychiatric conditions, such as anxiety, traumatic brain injury (TBI), or rare disorders like Kleine-Levin syndrome.

The phenomenon of a blank mind is increasingly understood as a response to cognitive overload, where the brain shuts down in the face of overwhelming information. This reaction can lead to a temporary paralysis of thought processes, leaving individuals feeling lost and unable to think clearly. To combat this, incorporating mindfulness techniques can be beneficial. Practicing mindfulness meditation not only enhances focus but also helps in managing stress levels. By fostering a calmer mental environment, individuals can significantly reduce the likelihood of experiencing those disorienting moments when their mind goes blank, particularly in high-pressure situations.

So, What’s Actually Happening in the Brain When It Blanks Out?

Behavioral studies and brain imaging research suggest that the brain is far from idle during these moments. Using electroencephalography (EEG), scientists found that the brain enters a state known as “local sleep.”

In this state, sleep-like brain waves, reduced signal complexity, a slower heart rate, and smaller pupil size are all signs typically associated with falling asleep. This fascinating finding supports the idea that blanking out may be more like a brief nap than a simple distraction.

In a separate 2019 study, researchers used functional magnetic resonance imaging (fMRI) to observe what happens when people intentionally try to clear their minds. They discovered that several regions of the brain appeared to switch off during this process, including the inferior frontal gyrus, Broca’s area, the supplementary motor cortex, and the hippocampus.

However, lead researcher Athena Demertzi and her team noted that because the participants chose to blank their minds on purpose, the brain activity might differ from what happens during spontaneous blanking.

“We realize that the investigation of mind blanks presents methodological and conceptual challenges,” the team wrote.

Overall, the researchers believe that mind blanking may occur when the brain is in either a very high or very low state of arousal. They hope this study encourages deeper exploration into the nature of thought, awareness, and consciousness.

The article highlights a fascinating aspect of how our brains operate under pressure. When we experience stress, our brains tend to prioritize emotional responses rather than engaging in logical thought processes. This shift can lead to those perplexing moments when our minds go blank, leaving us feeling disoriented.

During these stressful instances, the fight-or-flight response takes charge, making it difficult to think rationally. To mitigate this cognitive shutdown, the piece suggests employing techniques like cognitive restructuring. By reframing negative thoughts into more positive ones, individuals can enhance their mental clarity and reduce the risk of experiencing that unsettling blank state when under duress.

The recent study sheds light on the neurological phenomena that accompany those perplexing moments when our minds go blank. Understanding these brain processes is crucial for developing effective coping strategies. By integrating cognitive behavioral techniques with mindfulness practices, individuals can significantly bolster their ability to manage stress and sustain mental clarity during such episodes.

Moreover, the insights drawn from growth mindset theories highlight the importance of reframing challenges as learning opportunities. This approach not only encourages resilience but also enhances cognitive flexibility and emotional strength. In high-pressure environments, employing these strategies can lead to markedly improved outcomes, allowing individuals to navigate moments of mental blankness with greater ease and confidence.
