RT Journal Article SR Electronic T1 Visual Attention in The Fovea and The Periphery during Visual Search JF bioRxiv FD Cold Spring Harbor Laboratory SP 2021.11.22.469359 DO 10.1101/2021.11.22.469359 A1 Jie Zhang A1 Xiaocang Zhu A1 Shanshan Wang A1 Hossein Esteky A1 Yonghong Tian A1 Robert Desimone A1 Huihui Zhou YR 2021 UL http://biorxiv.org/content/early/2021/11/23/2021.11.22.469359.abstract AB Visual search depends on both the foveal and peripheral visual system, yet the foveal attention mechanisms is still lack of insights. We simultaneously recorded the foveal and peripheral activities in V4, IT and LPFC, while monkeys performed a category-based visual search task. Feature attention enhanced responses of Face-selective, House-selective, and Non-selective foveal cells in visual cortex. While foveal attention effects appeared no matter the peripheral attention effects, paying attention to the foveal stimulus dissipated the peripheral feature attentional effects, and delayed the peripheral spatial attentional effects. When target features appeared both in the foveal and the peripheral, feature attention effects seemed to occur predominately in the foveal, which might not distribute across the visual field according to common view of distributed feature attention effects. As a result, the parallel attentive process seemed to occur during distractor fixations, while the serial process predominated during target fixations in visual search.Competing Interest StatementThe authors have declared no competing interest.
