Microsaccades are small (<1°) fixational eye movements. Spatial biases in microsaccade direction reflect the focus of covert attentional selection [1]. Yet, whether microsaccades and covert attention are mediated by shared, or distinct, neural mechanisms remains actively debated [2-4]. For example, a recent study suggested that attentional modulations of neural activity in visual area V4 occur only when accompanied by microsaccades [2]. Yet, other studies have shown that behavioral and neural effects of attention occur regardless of microsaccades [3-4]. Here, we present novel evidence that
