Rats exhibit individual differences in their propensity to ingest sucrose and in their feeding
response to low doses of amphetamine (AMP). Rats with high baseline sugar intake (HIGH) …

Rats exhibit profound individual differences in their propensity to ingest sugar and in their
locomotor response to AMP. Intrinsic variation in the responsiveness of mesolimbic …

The effects of microinjections into the nucleus accumbens (N. ACC.) of 0.0, 2.0 or 8.0 μg of
(+)-amphetamine sulphate (AMPH) on foodintake and running wheel activity were …

Rats exhibit individual differences in their consumption of sugar and in their response to
amphetamine treatments. Intrinsic variation in the functioning of the mesolimbic dopamine …

Rats with high propensity to ingest sugar (HIGH) show increased responsiveness to
amphetamine treatments than rats with low propensity to ingest sugar (LOW). Intrinsic …

The present study tested whether rats release more accumbens dopamine (DA) during a
sugar binge when they are underweight vs. normal weight. Since acetylcholine (ACh) in the …

Previous research in this laboratory has shown that a diet of intermittent excessive sugar
consumption produces a state with neurochemical and behavioral similarities to drug …

Evidence indicates that amphetamine (AMP) affects feeding in a baseline-dependent
fashion and that the nucleus accumbens (Acc) is an important site of action for AMP's effects …

Amphetamine (AMP) administered in high doses suppresses feeding. However, in low
doses AMP has been shown to both suppress and facilitate feeding. Further, there is some …

Rationale: Previous studies have shown that individual differences in oral sucrose
consumption are predictive of the psychomotor and dopamine (DA) stimulant properties of …
