WebNov 21, 2024 · When activation procedures were performed, a photic “driving” response was recorded on sEEG during photic stimulation. Results: A photic “driving” response was the most robust at the right temporoparietooccipital junction (RTPOJ) lead, contacts 1-3. A sustained photic “driving” response was seen at all frequencies 3-30 Hz. WebSchizophrenia is a mental disorder characterized by both abnormal time perception and atypical relationships with external factors.
