BACKGROUND: Serotonin (5-HT) 1A and 2A receptors have been associated with dysfunctional emotional processing biases in mood disorders. These receptors further predominantly mediate the subjective and behavioral effects of psilocybin and might be important for its recently suggested antidepressive effects. However, the effect of psilocybin on emotional processing biases and the specific contribution of 5-HT2A receptors across different emotional domains is unknown. METHODS: In a randomized, double-blind study, 17 healthy human subjects received on 4 separate days placebo, psilocybin (215 μg/kg), the preferential 5-HT2A antagonist ketanserin (50 mg), or psilocybin plus ketanserin...

During a preliminary study comparing 5 normal subjects and 5 alcoholics (25 experiments) changes in evoked potentials were found in these patients. There was mainly a reduction in these potentials during the first 100 milleseconds following stimulation. Such a reduction generally means a disorder of the arrival of the influx at the level of the cortex and may be found mainly in peripheral nerve involvement. A complementary study of the H reflex (34 experiments) showed that this reflex was affected in 60% of chronic alcoholics whether or not they had liver cirrhosis...
