Research Abstract

Using functional magnetic resonance imaging (fMRI), we investigated brain when healthy participants read meaningful Japanese sentences. We attempted to determine the exact location of activation in the primary visual cortex and tried to find out whether the activation was dynamically controlled in accordance with the location of next saccade or was fixed at some location in the parafovea, for each participant. The activation occurs in the parafoveal V1 of the left hemisphere, and did not change with the distance to the next goal of saccade but was fixed on the area representing about 4.5° of eccentricity.
