I would like to point out that through practice the whole apparatus of thought and brain activity may be reconfigured (including the dominant areas, and there are more options than hemisphere.)<p>It is not surprising that psychedelics may trigger or reboot these internal features.<p>If we dug deeper, it might be that left hemisphere thinkers are more rigid in their thoughts, and right hemisphere are more psycho-emotive/intuitive.<p>Scientists have been known to credit their leaps to psychedelics.
