McCormick and Flavio Frohlich, a postdoctoral research associate, introduced slow oscillation signals into brain tissue and found that the signal created a sort of feedback loop, with changes in electrical field guiding neural activity, which in turn strengthened the electrical field.
“It’s like asking whether the roar of the crowd in the football stadium also influences you to cheer as well. And in turn, your cheering encourages others to cheer along with you.” McCormick said.
The ability of electric fields generated by the brain to influence its own activity appears to be particularly prominent during epileptic seizures. However, the influence of electric fields is not limited to these pathological states. The study of Frohlich and McCormick demonstrates that the electrical fields also influence brain function during normal activities such as sleep.
McCormick said the findings change the way in which we view brain function and may be of significant clinical value in controlling epilepsy, depression and other neural dysfunctional states.
