title: Dimethoxyaporphine as an antagonist of chemical excitation in the pigeon optic tectum.
abstract: The alkaloid L-5,6-dimethoxyaporphine (L-nuciferine) was studied with iontophoretic techniques, and its interaction with excitant amino acids on neurones of the pigeon optic tectum was tested. This compound antagonizes the action of L-glutamate and, to a weaker extent, that of L-aspartate and d,L-homocysteate. In comparison, L-5,6-dimethoxyaporphine did not reduce the acetylcholine evoked excitation.
