Aha moments fire as a right-temporal gamma burst
Quick answer
Aha moments fire as a right-temporal gamma burst. Today's question (Insight and the aha moment) asks about a finding from Jung-Beeman, M., Bowden, E. M., Haberman, J., Frymiare, J. L., Arambel-Liu, S., Greenblatt, R., Reber, P. J., & Kounios, J. in 2004. The correct option is A burst of high-frequency (gamma) activity over the right anterior temporal lobe just before solution — full explanation, primary source, and glossary cross-links below.
Today's question
Jung-Beeman et al. (2004) found that insight (aha) solutions to compound-remote-associate problems were preceded by a distinctive neural signature. What was it?
Reveal the answer and explanation
Correct: B — A burst of high-frequency (gamma) activity over the right anterior temporal lobe just before solution
Jung-Beeman et al. (2004) compared brains during compound-remote-associate problem solving for trials reported as 'aha' insight versus analytic step-by-step solutions. EEG and fMRI converged on the right anterior superior temporal gyrus: a sudden burst of gamma-band activity (~300 ms before button press) and a corresponding fMRI activation appeared selectively for insight solutions. The right hemisphere's broader semantic activation may help retrieve the distant association needed to crack remote-associate puzzles. The work gave neural plausibility to the long-standing distinction between gradual analytic search and sudden integrative restructuring.
