Key findings
- Rapid communication between brain areas appears to be common and is influenced by cognitive control
- Gamma enhancement neurofeedback was followed by better memory for associated information
- Gamma training was also followed by higher fluid intelligence scores
- Proposes that gamma activity, likely driven from frontal regions, supports control of linked information
A doctoral thesis on how the brain's specialised regions communicate so that information held in different places can be combined. Using fMRI and EEG, the work found that fast communication between regions is widespread and can be shaped by cognitive control. In the neurofeedback studies, training people to boost gamma-band activity was followed by better performance on short- and long-term memory for linked information and on fluid intelligence.
