The chronology of age-related spatial learning impairment in two rat strains, as tested by the Barnes maze.

30 May 2009 The Barnes maze offers advantages for cognitive aging studies, because of its relatively unstressful design and its modest physical demands. The authors therefore undertook a detailed chronological investigation of performance against age, for ...

Enhanced CaMKII activity and spatial cognitive function in SAMP6 mice.

30 May 2009 Senescence-accelerated mouse prone 6 (SAMP6) mice exhibit increased expression of NMDA receptor NR2B subunit (NR2B) and improved short-term memory compared with senescence-accelerated mouse resistance 1 (SAMR1) mice. The Thr286 phosphorylation of ...

Pretraining does not ameliorate spatial learning deficits induced by intrahippocampal infusion of AP5.

30 May 2009 Previous studies show discrepancies concerning the effects of pretraining on spatial learning deficits induced by blockade of the N-methyl-D-aspartate (NMDA) receptor. These inconsistencies might be attributed to the differences in the nature of the ...

Lesions of the fornix and anterior thalamic nuclei dissociate different aspects of hippocampal-dependent spatial learning: implications for the neural basis of scene learning.

30 May 2009 The present study used 2 different discrimination tasks designed to isolate distinct components of visuospatial learning: structural learning and geometric learning. Structural learning refers to the ability to learn the precise combination of ...

Deficits in landmark navigation and path integration after lesions of the interpeduncular nucleus.

30 May 2009 Experiments were designed to determine the role of the interpeduncular nucleus (IPN) in 3 forms of navigation: beacon, landmark, and path integration. In beacon navigation, animals reach goals using cues directly associated with them, whereas in ...

Spatial grouping determines temporal integration.

30 May 2009 To make sense out of a continuously changing visual world, people need to integrate features across space and time. Despite more than a century of research, the mechanisms of features integration are still a matter of debate. To examine how temporal ...

Intrinsic orientation and study viewpoint in recognizing spatial structure of a shape.

30 May 2009 Two experiments dissociated the roles of intrinsic orientation of a shape and participants' study viewpoint in shape recognition. In Experiment 1, participants learned shapes with a rectangular background that was oriented differently from their ...

Enriched environment fails to increase meningitis-induced neurogenesis and spatial memory in a mouse model of pneumococcal meningitis.

30 May 2009 An increase in adult neurogenesis was observed after exposure to enriched environment (EE) and during reconvalescence from experimental pneumococcal meningitis. This study investigated neurogenesis and spatial learning performance 5 weeks after ...

Comparing dogs and great apes in their ability to visually track object transpositions.

25 May 2009 Knowing that objects continue to exist after disappearing from sight and tracking invisible object displacements are two basic elements of spatial cognition. The current study compares dogs and apes in an invisible transposition task. Food was ...

Tactile-auditory saltation: spatiotemporal integration across sensory modalities.

25 May 2009 The perceptual phenomena of sensory saltation involve the systematic displacement of a target stimulus (the attractee) towards a subsequent stimulus (the attractant), which occurs closely in time and space. Here, we demonstrate the existence of ...
