The central nervous system — comprising the brain and spinal cord — coordinates perception, cognition, emotion and behavior, and constitutes the main biological substrate through which psychoactive plants and traditional medicines exert their effects. Research on compounds such as DMT, harmala alkaloids, ibogaine, mescaline or cannabinoids examines how they interact with neurotransmitter systems, neural plasticity and brain network dynamics. ICEERS gathers here scientific content addressing these mechanisms.
