Rapid advances in neuroscience have sparked numerous efforts to study the neural correlate of consciousness. Prominent subjects include higher sensory area, distributed assemblies bound by synchronization of neuronal activity and neurons in specific cortical laminae. In contrast, it has been suggested that the quality of sensory awareness is determined by systematic change of afferent signals...
Abstract Various ultraviolet, infrared, and TLC procedures are described for the separation and identification of hallucinogenic drugs. Specific methods for LSD, DMT, and psilocybin are also presented, along with general background information for the hallucinogenic drugs.
