Increased attentional precision enhances the attraction of population receptive fields toward the attended location, impacting visual processing.
Using 7T fMRI, we found significant blood oxygenation level-dependent response amplitude changes based on attentional focus, affecting receptive field attributes.
Focus on a small area increases foveal receptive field attraction, while broader attention disperses it, revealing dynamic cortical spatial tuning.
The Gaussian attention field model effectively explains the observed variations in receptive field attraction based on attentional precision.
