Covert spatial attention produces biases in perceptual and neural responses the absence of overt orienting movements. The mechanism that gives rise to these effects is poorly understood. Here we report relation between fixational eye movements, namely vergence, covert attention. Visual stimuli modulate angle vergence as a function their ability capture This illustrates bottom-up In visual auditory cue/no-cue paradigms, greater cue condition than no-cue condition. shows top-down component. conclusion, observations reveal close link modulation during fixation. Our study suggests basis for use tool measuring may provide new insights into disorders.
