Neuroleptic-induced striatal dopamine receptor supersensitivity in mice: relationship to dose and drug.

abstract：:Three sets of experiments were carried out in a Y water maze in which mice had to swim toward the light or the dark, in two different procedures. The first procedure involved, orientation toward a light source (L procedure), corresponding to natural preference, the latter involved orientation toward the dark (D proced...
