The latter region was also a significant predictor of the degree of contralesional slowing of target

detection and the extent to which ipsilesional distracters captured attention of neglect patients. Finally, damage to the FEF and posterior IPS was negatively correlated with the tendency of neglect patients to orient attention toward behaviourally relevant distracters. These findings support the results of functional imaging studies of spatial attention and provide evidence for a network account of neglect, according to which attentional selection of relevant environmental stimuli and the reorienting of attention result from dynamic interactions between the IPS, the dorsal premotor cortex, and the TPJ.

“Small numbers of graduates from few medical schools, and emigration of graduates to other countries, contribute to low physician presence in sub-Saharan Africa. The Sub-Saharan African Medical School Study examined MRT67307 in vivo the challenges, innovations, and emerging trends in medical education in the region. We identified 168 medical schools; of the 146 surveyed, 105 (72%) responded. Findings from the study showed that countries are prioritising medical education scale-up as part of health-system this website strengthening, and we identified many innovations in premedical preparation, team-based education, and creative use of

scarce research support. The study also drew attention to ubiquitous faculty shortages in basic and clinical sciences, weak physical infrastructure, and little use of external accreditation. Patterns recorded include the growth of private medical schools, community-based secondly education, and international partnerships, and the benefit of research for faculty development.

Ten recommendations provide guidance for efforts to strengthen medical education in sub-Saharan Africa.”
“Whether mental visual images play a functional role in cognition or that propositional knowledge is sufficient for supporting performance in imagery tasks is a long-standing debate. It cannot be resolved using behavioural data alone, nor by brain imaging data alone; for example, across fMRI studies mental rotation has been shown to involve virtually all areas of the brain. Alternatively participants might adopt different cognitive strategies. We report behavioural and fMRI data for mental rotation from individuals reporting vivid or poor mental imagery. Groups differed in errors but not response times, and differed in brain activation patterns, suggesting that the groups performed the same task in different ways. (C) 2011 Elsevier Ltd.

“Rats were used in a lick suppression preparation to assess the contribution of conditioned-stimulus (CS)-context and context-unconditioned-stimulus (US) associations to experimental extinction. Experiment 1 investigated whether strengthening the CS-acquisition context association enhances extinction by determining whether stronger extinction is observed when CS-alone trials (i.
