The brain’s ability to return to focus after distraction is a fascinating phenomenon that has now been shed more light on by a new study from the Picower Institute at MIT. The researchers discovered that the brain uses rotating waves of neural activity to restore focus after an interruption. These waves, which occur in the prefrontal cortex, synchronize neurons in circular patterns, similar to starlings in flight, to overcome cognitive interruptions.
The study, published in the Journal of Cognitive Neuroscience, shows that complete rotations of these waves correlate with correct task performance, while incomplete rotations lead to errors. These findings suggest that the brain uses these energy-efficient, traveling waves as a natural analogue computation system to restore concentration after disruptions.
The researchers used electrical recordings from animals to analyze neural activity in the prefrontal cortex, an area of the brain responsible for higher cognitive functions. They found that neural activity is highly coordinated and that this rotating organization helps maintain focus. Interestingly, these rotations only occurred when there was a distraction that the animals tried to ignore.
The results of the study could have far-reaching implications for understanding brain function. They show that the brain uses analog traveling waves to efficiently restore attention and process information. These findings could open up new approaches to improving cognitive performance and developing technologies to support concentration.
