This study explored on-line processing of local syntactic dependencies in normal subjects and in Broca's and Wernicke's aphasics using a lexical decision paradigm. In addition, subjects performed a grammatically judgement task on the real word pairs used in the lexical decision tasks. Results of two experiments for normal subjects indicated different(More)
Solving a problem with an "a-ha" effect is known as insight. Unlike incremental problem solving, insight is sudden and unique, and the question about its distinct brain activity, intrigues many researchers. In this study, electroencephalogram signals were recorded from 12 right handed, human participants before (baseline) and while they solved a spatial(More)
We prove that the Atiyah-Singer Dirac operator / D g in L 2 depends Riesz continuously on L ∞ perturbations of complete metrics g on a smooth man-ifold. The Lipschitz bound for the map g → / D g (1 + / D 2 g) − 1 2 depends on bounds on Ricci curvature and its first derivatives as well as a lower bound on injectiv-ity radius. Our proof uses harmonic analysis(More)
