STUDY DESIGN AND METHODS: An assessment tool was developed, daily activities in Afghanistan were observed, and key personnel were interviewed...
Most functional magnetic resonance imaging studies use linear models to predict the measured response by convolution of an impulse response with the stimulus profile. Using very short visual presentation times (<2 s), deviation from the linear model in the measured BOLD data from the human brain was found for the response integral, amplitude, and width. In this study, high temporal and spatial...
