Reduced facilitation effect of collinear flankers on contrast detection reveals impaired lateral connectivity in the visual cortex of schizophrenia patients.


The aim of this study was to investigate lateral connectivity in early visual cortex of schizophrenia patients. Contrast thresholds were measured for centrally presented Gabor patches which were surrounded by two collinear or orthogonal flankers. The healthy subjects (n = 15) showed lower contrast thresholds for central Gabor patches when collinear flankers… (More)
