This study investigated how different stages of cocaine self-administration in rats affect the expression of two serotonin receptors in dorsal and ventral striatum, the 5-HT(1B) and 5-HT(6) subtypes, which have both been implicated in mediating some ...

Interoceptive effects of alcohol require mGlu5 receptor activity in the nucleus accumbens.
27 Jul 2009 The interoceptive effects of alcohol are major determinants of addiction liability. Metabotropic glutamate (mGlu) receptors are widely expressed in striatal circuits known to modulate drug-seeking. Given that the interoceptive effects of drugs can ...

22 Jul 2009 alpha(1)-Adrenoceptors are concentrated in the locus coeruleus (LC) where they appear to regulate various active behaviors but have been difficult to stimulate effectively. The present study examined the behavioral, pharmacological and neural ...

19 Jul 2009 The root part of Paeonia lactiflora Pall. (Ranunculaceae), commonly known as peony, is a commonly used Chinese herb for the treatment of depression-like disorders. Previous studies in our laboratory have demonstrated that total glycosides of peony ...

Dissociated fear and spatial learning in mice with deficiency of ataxin-2.
18 Jul 2009 
Mouse models with physiological and behavioral differences attributable to differential plasticity of hippocampal and amygdalar neuronal networks are rare. We previously generated ataxin-2 (Atxn2) knockout mice and demonstrated that these animals ...

14 Jul 2009 AZD0328, a novel spirofuropyridine neuronal nicotinic receptor partial agonist, was used to investigate the role of alpha7 neuronal nicotinic receptor (NNR) activation in the modulation of midbrain dopamine neuron function, cortical dopamine release ...

Midbrain dopamine neurons signal preference for advance information about upcoming rewards.
14 Jul 2009 The desire to know what the future holds is a powerful motivator in everyday life, but it is unknown how this desire is created by neurons in the brain. Here we show that when macaque monkeys are offered a water reward of variable magnitude, they ...

13 Jul 2009 The pedunculopontine tegmental nucleus (PPTg) is in a key position to participate in operant reinforcement via its connections with the corticostriatal architecture and the medial reticular formation. Indeed, previous work has demonstrated that rats ...

13 Jul 2009 The orbitofrontal cortex (OFC) has been implicated in decision-making under uncertainty, but it is unknown how information about the probability or uncertainty of future reward is coded by single orbitofrontal neurons and ensembles. We recorded ...

Learning and memory: how sea slug behaviors become compulsive.
12 Jul 2009 A recent study of how food-seeking behavior in the sea slug Aplysia becomes compulsive provides new insights into the neural mechanisms of operant ...
