| الوصف: | The mechanism of amobarbital action during the intracarotid amobarbital procedure is poorly understood. We report a patient case who underwent IAP while implanted with bilateral stereo-EEG. We analyzed the spectral power, phase amplitude coupling, and cluster-phase group synchrony during the procedure. Delta and gamma power increased bilaterally. By contrast, phase amplitude coupling increased only ipsilateral to the injection. Similarly, 4–30 Hz cluster-phase group synchrony declines and gamma cluster-phase group synchrony increases only ipsilateral to the injection. These results suggest that a possible additional mechanism for amobarbital action in the IAP is by altering the precise timing of oscillatory activity. Highlights • Intracranial activity shows bilateral increases in delta and gamma activity during the IAP. • Phase amplitude coupling increases in the 2–3 Hz (phase) and 30–70 Hz (amplitude) band only ipsilateral to the injection. • 4–30 Hz synchrony declines and gamma synchrony increases only ipsilateral to the injection. • Amobarbital may alter the temporal organization of activity, rather than inactivation of the injected hemisphere. |
