The role of the nucleus accumbens (NAC) and ventral pallidum (VP) in food reward modulation was investigated using Heyman's [24] curve fitting approach in food deprived rats. All rats were maintained at 80% normal body weight, and trained to lever press for food reinforcement. Each rat was tested daily with a series of four variable-interval (VI) reinforcement schedules (80, 40, 20, and 10 s) designed to approximate an exponential distribution, and randomly administered in ascending or… Expand
Role of ventral hippocampal NMDA receptors in anxiolytic-like effect of morphine
TLDR
The results suggest that VH-NMDA receptors participate in the mediation of morphine-induced anxiolytic-like behavior. Expand
Involvement of dopaminergic and glutamatergic systems of the basolateral amygdala in amnesia induced by the stimulation of dorsal hippocampal cannabinoid receptors
TLDR
Findings support the existence of a functional interaction between dorsal hippocampal and basolateral amygdaloid neural circuits during processing cannabinoid-induced amnesia in male Wistar rats. Expand
Additive effect of BLA GABAA receptor mechanism and (+)-MK-801 on memory retention deficit, an isobologram analysis
TLDR
Muscimol and bicuculline decreased retention of memory formation in the BLA, and GABAA receptors in theBLA may be involved in the additive effect on (+)-MK-801-induced memory retention deficits. Expand
Increased alcohol intake and behavioral disinhibition in rats with ventral striatal neuron loss
TLDR
The results suggest that ventral striatal neuron loss gives rise to excessive alcohol drinking and enhanced impulsivity. Expand
The effect of GABA-B receptors in the basolateral amygdala on passive avoidance memory impairment induced by MK-801 in rats
TLDR
The results indicated that BLA GABA-B receptors can alter the effect of NMDA inactivation on passive avoidance memory. Expand

Novelty seeking and harm avoidance in relation to alcohol drinking in intact rats and following axon-sparing lesions to the amygdala and ventral striatum.
TLDR
Examination of whether excessive alcohol-consuming rats have a diminished response to potential danger and an enhanced tendency to explore novel surroundings and a possible relationship between the above-mentioned behavioural parameters and two of the emotional motor systems in the basal forebrain suggests that intact animals high in novelty seeking drink more alcohol than rats low on this trait. Expand
Role of glutamate receptors in the nucleus accumbens on behavioural responses to novel conflictive and non-conflictive environments in the rat
TLDR
The present results are compatible with the concept that glutamatergic input fibres to the nucleus accumbens modulate the expression of exploratory behaviour induced by novelty in conflictive and non-conflictive conditions. Expand
Forebrain circuitry involved in effort-related choice: Injections of the GABAA agonist muscimol into ventral pallidum alter response allocation in food-seeking behavior
TLDR
Data indicate that stimulation of GABA receptors in ventral pallidum produces behavioral effects similar to those produced by accumbens dopamine depletions, and appears to be a component of the brain circuitry regulating response allocation and effort-related choice behavior. Expand
The Ventral Pallidum and Hedonic Reward: Neurochemical Maps of Sucrose “Liking” and Food Intake
TLDR
A novel microinjection and functional mapping procedure to neuroanatomically localize and neurochemically characterize substrates in the VP that mediate increases in eating behavior and enhancements in taste hedonic “liking” reactions reveals that VP generation of increased food reward and increased eating behavior is related but dissociable.

N-Methyl-d-aspartic acid-induced lesions of the nucleus accumbens and/or ventral pallidum fail to attenuate lateral hypothalamic self-stimulation reward
TLDR
The above data suggests that the nucleus accumbens and the ventral pallidum are not critical for ICSS rewards stimulation and that hypothalamic ICSS reward signals are processed downstream from these limbic structures. Expand
Two discrete nucleus accumbens projection areas differentially mediate cocaine self-administration in the rat
TLDR
The importance of another nucleus accumbens output, the subcommissural ventral pallidum (SVP), in mediating the self-administration of cocaine in the rat was explored and the effect was found to be greater for the rats bearing lesions of the SEA. Expand
Comparison of delta opiate receptor agonist induced reward and motor effects between the ventral pallidum and dorsal striatum
TLDR
It is demonstrated that the ventral pallidum and the mediocentral caudate play a role in modulating opiate rewards, and adds to the growing body of literature regarding the regional heterogeneity within the caudates and ventral Pallidum. Expand
Potentiation of reward-related responding by psychostimulant infusion into nucleus accumbens: Role of dopamine receptor subtypes
The conditioned-reinforcement paradigm measures the ability of a conditioned stimulus to act as a reinforcer for newly learned operant behavior. The following experiments had two objectives. First,Expand
Extinction and recovery of cocaine self-administration following 6-hydroxydopamine lesions of the nucleus accumbens
TLDR
The hypothesis that non-striatal dopamine may subserve cocaine reward is supported, as several 6-OHDA treated animals displayed a pattern of behaviour resembling extinction, where a high rate of lever pressing was followed by cessation of responding. Expand
Disruption of cocaine self-administration following 6-hydroxydopamine lesions of the ventral tegmental area in rats
TLDR
The hypothesis that dopaminergic mechanisms are necessary for the normal expression of cocaine self-administration is supported. Expand
Microinjections of flupenthixol into the caudate-putamen but not the nucleus accumbens, amygdala or frontal cortex of rats produce intra-session declines in food-rewarded operant responding
TLDR
It was concluded that dopaminergic projections to the dorsal caudate-putamen may play a critical role in mediating the effects of food-reward on operant responding. Expand
Increased food intake after opioid microinjections into nucleus accumbens and ventral tegmental area of rat
TLDR
It was concluded that there are sites in the ACC and VTA where increased activity of endogenous opioid peptide systems reliably increase food intake and it was hypothesized that these sites may contribute to changes in ingestive behavior after systemic morphine administration. Expand
Depletion of dopamine in the caudate nucleus but not in nucleus accumbens impairs reaction-time performance in rats

TLDR
The results show that moderate decreases in dopamine function restricted to the corpus striatum can disrupt sensitive motor performance, and support the hypothesis that dopamine in the corpusstriatum has a role in the initiation of complex goal- directed responses. Expand
Regional neuroleptic microinjections indicate a role for nucleus accumbens in lateral hypothalamic self-stimulation reward
TLDR
Results indicate a major role for accumbens DA in MFB reward, but not for the DA in caudate and medial frontal cortex and confirm the reward effects of acute DA receptor blockade, but produced a greater associated motor/performance impairment. Expand
