Double dissociation and hierarchical organization of strategy switches and reversals in the rat PFC.
29 Sep 2009 
Prelimbic-infralimbic cortex (PL-IL) and orbitofrontal cortex (OFC) influence behavioral flexibility in the rat. The authors tested the effects of PL-IL or OFC infusion with the GABA agonist muscimol in the context of 2 flexible responding tasks: ...

29 Sep 2009 Local availability of glycine near N-methyl-D-aspartate receptors (NMDARs) is partly regulated by neuronal glycine transporter 1 (GlyT1), which can therefore modulate NMDAR function because binding to the glycine site of the NMDAR is necessary for ...

The time course of task switching: a speed--accuracy trade-off analysis.
29 Sep 2009 On each trial of this study, participants either switched between or repeated two simple, two-choice tasks involving either letter or digit classifications. Speed-accuracy trade-off (SAT) curves were obtained using the response-signal method of ...

29 Sep 2009 Recent task-switching studies in which a predictable task sequence has been used have indicated that verbal representation contributes to the control of task order information. The present study focused on the role of verbal representation in ...

Distinct hippocampal and basal ganglia contributions to probabilistic learning and reversal.
30 Aug 2009 The hippocampus and the basal ganglia are thought to play fundamental and distinct roles in learning and memory, supporting two dissociable memory systems. Interestingly, however, the hippocampus and the basal ganglia have each, separately, been ...

25 Aug 2009 The striatum plays a major role in both motor control and learning and memory, including executive function and "behavioral flexibility." Lesion, temporary inactivation, and infusion of an N-methyl-d-aspartate (NMDA)-receptor antagonist into the ...

Oxygen treatment triggers cognitive impairment in Alzheimer's transgenic mice.
3 Aug 2009 An association between major surgery in the elderly and precipitation of Alzheimer's disease has been reported. As 100% oxygen (hyperoxia) is commonly administered after surgery, we exposed cognitively unimpaired Alzheimer's transgenic mice to ...

30 Jul 2009 Nakamura, Fujita, Ushitani, & Miyata (2006) have shown that pigeons perceive the standard Müller-Lyer illusion. In this report, the authors examined effects of bracket sizes on perception of this illusion in pigeons (Columba livia) and humans (Homo ...

Representations of single and compound stimuli in negative and positive patterning.
30 Jul 2009 In four experiments, rats were trained on different patterning discriminations before being tested with compounds composed of novel combinations of the trained stimuli. In Experiment 1, rats were trained on a negative-patterning schedule (A+ B+ AB-) ...

Learning about associations: evidence for a hierarchical account of occasion setting.
29 Jun 2009 In 2 experiments rats were trained on a switching discrimination, with 4 occasion setters, A, B, C, and D and 2 target stimuli, x and y. When signaled either by A or by B, x was reinforced with food and y was not, whereas when signaled either by C ...
