Psychoactive Insights: Entropy and Consciousness
Research indicates that the effects of psychoactive substances on conscious experience can vary significantly. THC, which causes dose-dependent intoxication, raises questions about whether increases in entropy relate to enhanced richness of consciousness or simply reflect increased arousal. In contrast, stimulant substances like methamphetamine, known for their energizing effects, do not elevate entropy levels in spontaneous brain activity, suggesting that not all pro-arousing substances contribute similarly to the complexity of conscious experience. This differentiation is crucial for understanding how different psychoactives affect brain dynamics and consciousness.
