The Vision Taxonomy of Dr. Rouhier, in his classic work on mescaline intoxication

The French physician Rouhier, in his classic work on mescaline intoxication, attempted to classify the types of visions experienced under its influence. Importantly, he stressed that these types are not sequential stages (like a ladder of progression) but rather modes of experience that often overlap. In most mescaline states, one type tends to dominate, while … Continue reading The Vision Taxonomy of Dr. Rouhier, in his classic work on mescaline intoxication

When Sound Becomes Light: Synaesthesia, Mescaline, and the Phosphene Connection

Among the many mysteries of human perception, synaesthesia is quite interesting. Crossing of the senses where sound becomes colour, where touch radiates as light, or where vision itself resonates like a musical chord. In early mescaline research, such synaesthetic states were already frequently documented. Investigators noticed that the excitation of one sensory organ would spill … Continue reading When Sound Becomes Light: Synaesthesia, Mescaline, and the Phosphene Connection
