Effects of the South American psychoactive beverage ayahuasca on regional brain electrical activity in humans: a functional neuroimaging study using low-resolution electromagnetic tomography

Functional neuroimaging study using LORETA showing ayahuasca activates frontal and paralimbic brain regions. Found increased current density in anterior cingulate and frontal medial cortex. Neurophysiological changes correlated with subjective effects and serotonergic modulation.
