Thinking in sync: How brain rhythms support intelligence

When the brain is under pressure, certain neural signals begin to move in sync—much like a well-rehearsed orchestra. A new study from Johannes Gutenberg University Mainz (JGU) is the first to show how flexibly this neural synchrony adjusts to different situations and that this dynamic coordination is closely linked to cognitive abilities.

Brain Flexibility, Not Constant Focus, Marks Intelligence

New research shows that individuals with higher cognitive ability have stronger, more flexible synchronization of brain rhythms—specifically theta waves—in the midfrontal region during mentally demanding tasks. These neural signals coordinate dynamically, especially during moments of decision-making, allowing people to maintain focus and adapt more quickly to changing rules.
