Delay activity in rodent frontal cortex during a simple reaction time task.
30 Mar 2009 
To understand how different parts of the frontal cortex control the timing of action, we characterized the firing patterns of single neurons in two areas of rodent frontal cortex-dorsomedial prefrontal cortex (dmPFC) and motor cortex-during a simple ...

30 Mar 2009 Both the anterior cingulate cortex (ACC) and mesolimbic dopamine, particularly in the nucleus accumbens (NAc), have been implicated in allowing an animal to overcome effort constraints to obtain greater benefits. However, their exact contribution to ...

30 Mar 2009 We recently reported that the mGlu5 receptor antagonist 2-methyl-6-(phenylethynyl)pyridine (MPEP) reduces intravenous self-administration of ketamine and, to a lesser extent, heroin in rats. We also found that MPEP potentiates conditioned place ...

Early lead exposure effects on an auditory threshold task in the rhesus monkey (Macaca mulatta).
30 Mar 2009 Behavioral thresholds to pure tones were obtained from adult rhesus monkeys that had been exposed to lead during early development and unexposed cohort controls. Thresholds were elevated (by 2-9 dB) for the previously lead exposed monkeys at all ...

Factors determining the effects of associative activation on habituation.
30 Mar 2009 In 2 experiments, rats received flavor-aversion conditioning with two flavors, B and C, to which they had been preexposed. In both experiments, C was preexposed in compound with another flavor in a block of CX trials. In Experiment 1, B was ...

Reinforcer probability, reinforcer magnitude, and the reinforcement context for remembering.
30 Mar 2009 Traditional theories of delayed matching-to-sample performance do not predict that accuracy will improve when absolute levels of reinforcement are increased. This prediction emerges only when reinforcement context is considered (J. A. Nevin, M. ...

Do pigeons (Columba livia) study for a test?
30 Mar 2009 In 4 experiments, the authors asked whether pigeons (Columba livia) would show metamemory by choosing to study a sample stimulus before taking a memory test. In Experiments 1a-1c, pigeons chose between cues that led either to exposure to a sample ...

Novel neural correlates of operant conditioning in normal and differentially reared Lymnaea.
30 Mar 2009 The aerial respiratory behaviour of the mollusc Lymnaea stagnalis is an important homeostatic behaviour that can be operantly conditioned. The central pattern generator underlying this behaviour, as well as motorneurons innervating the respiratory ...

30 Mar 2009 Rodents suppress intake of saccharin when it is paired with a drug of abuse (Goudie, Dickins, & Thornton, 1978; Risinger & Boyce, 2002). By the authors' account, this phenomenon, referred to as reward comparison, is thought to be mediated by ...

30 Mar 2009 The serotonin 5-HT2A receptor (5-HT-sub(2A)R) may play a role in reinstatement of drug-seeking. This study investigated the ability of a selective 5-HT-sub(2A)R antagonist to suppress reinstatement evoked by exposure to cues conditioned to cocaine ...
