The spatial properties of visual attention and its relation to attentional effort have been investigated, and it has been found that stimulus detectability changes as a function of attentional beam width and degree of task difficulty. Using a matching-to-sample paradigm, two Gabor patches were presented simultaneously both as a sample stimulus and a test(More)
Cancer-testis (CT) genes are expressed in various cancers but not in normal tissues other than in cells of the germline. Although DNA demethylation of promoter-proximal CpGs of CT genes is linked to their expression in cancer, the mechanisms leading to demethylation are unknown. To elucidate such mechanisms we chose to study the Caco-2 colorectal cancer(More)
