Key findings

  • Participants learned to raise gamma power when given neurofeedback
  • Greater gamma increases were associated with smaller feature-binding costs
  • Greater gamma increases were associated with higher intelligence scores
  • Suggests binding control and intelligence may share a common mechanism

Gamma-band synchrony has been tied both to how the brain links features of an object together and to intelligence. In this study participants received neurofeedback aimed at raising gamma power, and their feature-binding performance and intelligence scores were measured. People were able to increase gamma power with feedback, and larger increases went along with lower binding costs and higher intelligence scores.
