Abstract

Dopamine (DA) is a neurotransmitter that has been implicated in a wide variety of psychiatric disorders that include attention deficit-hyperactivity disorder (ADHD), schizophrenia, and drug abuse. Recently, we have been working with a mouse in which the gene for the DA transporter (DAT) has been disrupted. This mouse is hyperactive in the open field, displays an inability to inhibit ongoing behaviors, and is deficient on learning and memory tasks. Psychostimulants such as amphetamine and methylphenidate attenuate the hyperlocomotion of the mutants, but stimulate activity of the wild type (WT) controls. The objective of the present study is to examine the neural basis for the differential responses to psychostimulants in these mice. WT and DAT knockout (KO) animals were given vehicle or methylphenidate, amphetamine, or cocaine and brain sections were immunostained for Fos. In WT mice, methylphenidate induced Fos-like immunoreactivity (Fos-LI) in the mesostriatal and mesolimbocortical DA pathways that included the anterior olfactory nucleus, frontal association cortex, orbitofrontal cortex, cingulate cortex, caudate-putamen, globus pallidus, claustrum, lateral septum, nucleus accumbens, basolateral and central nuclei of the amygdala, bed nucleus of stria terminalis, subthalamic nucleus, substantia nigra, ventral tegmental area, and dorsal raphe. Additional areas of activation included the granular dentate gyrus, Edinger-Westphal nucleus, and periaqueductal gray. While the mutants showed little response in most of these same areas, the anterior olfactory nucleus, caudal caudate-putamen, lateral septum, basolateral and central nuclei of the amygdala, and bed nucleus of stria terminalis were activated. Amphetamine and cocaine produced similar changes to that for methylphenidate, except these psychostimulants also induced Fos-LI in the nucleus accumbens of the KO animals. Since the DAT gene is disrupted in the KO mouse, these findings suggest that dopaminergic mechanisms may mediate the WT responses, whereas non-dopaminergic systems predominate in the mutant. In the mutants, it appears that limbic areas and non-dopaminergic transmitter systems within these brain regions may mediate responses to psychostimulants. Inasmuch as the KO mouse may represent a useful animal model for ADHD and because psychostimulants such as cocaine are reinforcing to these animals, our results may provide some useful insights into the neural mechanisms-other than DA-that may contribute to the symptoms of ADHD and/or drug abuse in human patients.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
