Accuracy and sensitivity of detection of activation foci in the brain via statistical parametric mapping: a study using a PET simulator.

abstract：:Response inhibition, or the suppression of prepotent but contextually inappropriate behaviors, is essential to adaptive, flexible responding. Individuals with autism spectrum disorders (ASD) consistently show deficient response inhibition during antisaccades. In our prior functional MRI study, impaired antisaccade per...
