Correction to: Acute phenylalanine/tyrosine depletion of phasic dopamine in the rat brain.

abstract：:Risperidone was studied in a 0.16 mg/kg LSD-saline drug discrimination test procedure. At doses varying from 0.0025 to 0.63 mg/kg, no LSD-like agonist effects were observed. Studies on the antagonism of the LSD-cue indicated that risperidone was able to completely block the discriminative stimulus properties of LSD wi...
