(A) Covert orienting of attention involves selecting a peripheral location in space (here *) while the eyes remain at the center of the screen. (B) Attention orientation results in faster response times and higher detection rates in response to visual stimuli presented at the attended location, as compared to the non-attended location. (C) Attention orientation enhances both the phasic and tonic neuronal response components in several cortical areas including the frontal eye fields (FEF). Schematic representation of this effect onto multi-unit neuronal activity. (D) Online monitoring of the spatial locus of attention. On the left: the subject is covertly moving his attention to covertly explore the screen. On the right: the decoder interprets in real time the activity related to the subject’s attention orientation.
