Discrimination learning in Rora(sg) and Grid2(ho) mutant mice.

23 Jun 2008 Rora(sg) mutants with mild cerebellar granule cell degeneration were compared to Grid2(ho) mutants with more severe granule cell degeneration as well as Purkinle cell atrophy for left-right and dark-light discrimination learning tasks in a ...

Spatial information processing consequences of DAMGO injections into the dorsal striatum.

22 Jun 2008 The purpose of the present study was to examine the role of the dorsal striatum, and more specifically, the patch region of the dorsal striatum, in mediating spatial learning and memory. To this end, male, Long Evans rats were bilaterally implanted ...

Prefrontal cortex or basolateral amygdala lesions blocked the stress-induced inversion of serial memory retrieval pattern in mice.

22 Jun 2008 Previous data from our team have shown that pre-test stress in mice reversed the pattern of memory retrieval in a contextual serial spatial task (CSD; Celerier, A., Pierard, C., Rachbauer, D., Sarrieau, A., & Beracochea, D. (2004). Contextual and ...

Determining a role for ventromedial prefrontal cortex in encoding action-based value signals during reward-related decision making.

9 Jun 2008 Considerable evidence has emerged to implicate ventromedial prefrontal cortex in encoding expectations of future reward during value-based decision making. However, the nature of the learned associations upon which such representations depend is ...

Age differences in response selection for pure and mixed stimulus-response mappings and tasks.

7 Jun 2008 Two experiments examined effects of mixed stimulus-response mappings and tasks for older and younger adults. In Experiment 1, participants performed two-choice spatial reaction tasks with blocks of pure and mixed compatible and incompatible ...

Age-related differences in switching between cognitive tasks: does internal control ability decline with age?

30 May 2008 The present study tested the hypothesis that older adults establish a weaker task set than younger adults and therefore rely more on stimulus-triggered activation of task sets. This hypothesis predicts that older adults should have difficulty with ...

More dissociations and interactions within central executive functioning: a comprehensive latent-variable analysis.

19 May 2008 The present study examined the separability of six executive functions (verbal storage-and-processing coordination, visuospatial storage-and-processing coordination, dual-task coordination, strategic retrieval, selective attention, and shifting) and ...

Prefrontal-inferotemporal interaction is not always necessary for reversal learning.

19 May 2008 Prefrontal cortex (PFC) is thought to have a wide-ranging role in cognition, often described as executive function or behavioral inhibition. A specific example of such a role is the inhibition of representations in more posterior regions of cortex ...

Neonatal ventral hippocampus lesions disrupt extra-dimensional shift and alter dendritic spine density in the medial prefrontal cortex of juvenile rats.

17 May 2008 Recent data showed that neonatal ventral hippocampus (VH) lesions, an approach used to model schizophrenia symptoms in rodents, produce premature deficits of working memory believed to be associated with early medial prefrontal cortex (mPFC) ...

Complete recovery of olfactory associative learning by activation of 5-HT4 receptors after dentate granule cell damage in rats.

13 May 2008 Bilateral intradentate injections of 3.0microg of colchicine induced a substantial loss of granule cells and damage to the overlying pyramidal cell layer in region CA1 in adult male Long-Evans rats. All rats with such lesions showed a significant ...
