Dynamic changes in the cerebral metabolic rate of O2 and oxygen extraction ratio in event-related functional MRI.

abstract：:Results of this PET-O15 water activation study confirm the implication of supplementary motor areas during time estimation tasks. They also show that the cortical-subcortical network associated with temporal processing is impaired in schizophrenia. Following recent proposals of time dynamic networks, this impairment m...
