subsequent experiments performed with a neuroleptic ( haloperidol ) or a serotonin precursor ( 5-oh-tryptophan ) compared to those of d-lsd with and without apomorphine would indicate that d-lsd alone displays typical serotoninergic syndrome ( including inhibition of the climbing ) , whereas in the presence of apomorphine , an interaction at presynaptic receptors may possibly modulate dopaminergic activity .
