Özet
Hemodynamic responses of brain during single-event trials are measured by functional optical imaging (fOI) method. The response curves are modeled by a gamma function where the model fit yields the parameters related to the shape of each response. We found that during a twenty minutes target detection and categorization task, finger press reaction times have a quadratic relation to the amplitude and time constant of the gamma function.
