Previous studies have shown reductions of the functional magnetic resonance imaging (fMRI) signal in response to repetition of specific visual stimuli. We examined how adaptation affects the neural responses associated with categorization behavior, using face adaptation aftereffects. Adaptation to a given facial category biases categorization towards(More)
People track facial expression dynamics with ease to accurately perceive distinct emotions. Although the superior temporal sulcus (STS) appears to possess mechanisms for perceiving changeable facial attributes such as expressions, the nature of the underlying neural computations is not known. Motivated by novel theoretical accounts, we hypothesized that(More)
To assess the morphological changes of the hippocampus in Lewy body dementia (LBD) patients we used radial atrophy mapping, a mathematical modeling method sensitive to subtle differences in hippocampal shape. T1-weighted high resolution magnetic resonance (MR) scans were acquired from 14 LBD and 28 controls of similar age and gender, and were compared to(More)
