Evidence of cognitive activity in functional optical signals

We show that functional near infrared spectroscopy signals can monitor task-related cerebral hemodynamic response. We detect periodicities in the near infrared spectroscopy signals and show that the estimated periods are consistent across multiple detectors and subjects, despite the jittered periodi...

Summary:We show that functional near infrared spectroscopy signals can monitor task-related cerebral hemodynamic response. We detect periodicities in the near infrared spectroscopy signals and show that the estimated periods are consistent across multiple detectors and subjects, despite the jittered periodicity of the stimuli sequence that is used in a target categorization experiment.
