Abstract

This study was designed to investigate the relationship between the hyperactivity of magnocellular visual pathways and the attention deficit in schizophrenia. Magnocellular functions were evaluated with visual contrast sensitivity measurements, while attentional functions were assessed by measurements of the critical stimulus duration and the minimal number of stimulus presentation for feature extraction. The correlation between contrast sensitivity and the attentional parameters was also determined. Our results revealed the hyperactivity of magnocellular pathways and the impairment of attentional functions, but correlation was not found between them. This suggests that sensory inhibition deficit is independent of the attentional control dysfunctions in schizophrenia.
