Category Selective brain areas Psychology essay
Gandolfo and Downing show that perceptual expectations about an upcoming visual stimulus are reflected in the brain activity of category-selective brain areas: online transcranial magnetic brain stimulation over such areas selectively removes the behavioral effects of predictive verbal pre-cues on perceptual discrimination. of the filter varied across different scene-selective regions, suggesting differences in how scenes are represented in these regions. These results indicate that response patterns in scene-selective areas are sensitive to the low-level properties of the image, especially its spatial frequency content. FMRI Adaptation and Category Selectivity in the Human Ventral Temporal Cortex: Regional Differences Across Timescales Kevin S. Weiner, 1Rory Sayres, Joakim Vinberg, and Kalanit Grill-Spector1, Department of Psychology Neurosciences Institute, Stanford University, Stanford, California, Neuroimaging studies have in recent years has shown that certain object categories elicit a highly selective response in specific brain areas in the ventral brain regions. visual flow e.g. Aguirre et al. 1998, Epstein and Kanwisher, 1998, Kanwisher et al. 1996 for a recent review, see Op de Beeck, Haushofer, amp Kanwisher, 2008. Introduction. Models of human face perception suggest that facial identity and expression are processed along two distinct neural pathways Bruce and Young, 1986, Bruce and Young, 2012, Haxby et al. 2000. Support for the idea of separable pathways in face perception comes from neuroimaging studies that examined the selectivity. To address these gaps in knowledge, we examined the effect of attention on both visual category representations across the entire cortex and residual correlations between each cortical region in the brain and category-selective regions in VTC Kanwisher, 2010 Peelen and Downing, 2005, when their preferred category,
