Self-injection of amphetamine directly into the brain

Abstract

Rats learned to self-administer d-amphetamine (10 micrograms/microliter) through a cannula implanted in the nucleus accumbens. They responded more frequently for 65 +/- 15 nl of amphetamine than for equal amounts of saline. When presented with two levers (one amphetamine, one blank) they responded more on the correct lever for amphetamine. They would also switch levers, when necessary, to maintain access to the drug. When half the usual drug intake was given automatically, animals reduced their response rate by half, thus self-regulating the total amount of amphetamine they received. In tests for leakage into the ventricles, eight rats that self-injected with an accumbens cannula showed response extinction when switched to a ventricular cannula. We conclude that amphetamine self-injected into the accumbens is a positive reinforcer. This localization of 'amphetamine reward' suggests that the nucleus accumbens contains a synaptic mechanism underlying amphetamine abuse and, perhaps, also natural reinforcement of behavior.

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.
