The latest findings from brain imaging research suggest that those “aha! moments” you experience don’t just feel good – they actually change how your brain handles information, helping to lock it in your memory.
This research is published in Nature Communications.
While the study focused on brain activity before and after eureka moments, the researchers aim to delve into the intervals that lead to that sudden understanding.

These hidden picture puzzles acted as scaled-down representations of larger eureka moments.
The results were notable.
Participants were more likely to remember solutions that resulted from a sudden insight compared to those reached without such epiphanies. Moreover, those who felt more confident about their insights were more likely to recall them five days later.
For each puzzle solved, participants were asked whether the solution suddenly came to mind in a flash of insight or if they worked through it in a more systematic manner, as well as their level of certainty in their answer.
Additionally, they found that spotting the hidden object and seeing the image differently led to changes in neural activation patterns, especially in parts of the ventral occipito-temporal cortex, responsible for recognizing visual patterns. The intensity of the epiphany correlated with the extent of these changes.
“Learning environments that foster insight could boost long-term memory and understanding,” conclude the researchers.
They observed that insights trigger heightened activity in the hippocampus, a crucial brain structure for learning and memory. The stronger the insight, the greater the activity in this region.

Becker, working in the Cabeza lab, describes, “During these moments of insight, the brain reorganizes its perception of the image.”
The implications of this research reach into the realm of education, hinting that encouraging more of those “eureka moments” may enhance the longevity of learning beyond the confines of the classroom.
As Roberto Cabeza, a professor of psychology and neuroscience at Duke University and the senior author of the study, explains, these small discoveries mirror the characteristics found in more significant insights events.
In their investigation, researchers utilized functional magnetic resonance imaging (fMRI) to monitor participants’ brain activity as they attempted to unravel visual brain teasers. These puzzles asked individuals to decipher two-tone images with minimal detail, relying on their perception to complete the picture and identify real-world objects.

According to Maxi Becker, a postdoctoral fellow at Humboldt University in Berlin and the first author of the study, if you have an aha moment when solving something, you’re more likely to recall the solution later on.
The study involved mapping the brain activity of 31 participants using fMRI as they solved hidden picture puzzles. Increased blood flow to relevant brain regions correlated with the intensity of their “aha! moments.”
Finally, stronger “aha!” moments were linked with increased connectivity between different brain regions. Cabeza notes, “The brain regions communicate more effectively during these instances.”
Cabeza, who has dedicated 30 years to studying memory, emphasizes that experiencing an “aha moment” while learning substantially boosts memory and is one of the most powerful memory effects.
According to Cabeza, insight is pivotal for creativity. The findings not only offer insights into the brain’s creative problem-solving processes but also support inquiry-based learning approaches in education settings.
The researchers identified several changes in the brain associated with better memory retention of these “aha moments.”
