Top down & bottom up attention


In everyday life, we engage several visual searches when looking for something or someone in the environment. This research line aims to investigate how top-down and bottom-up attention interact in visual search and the neural mechanism involved in this interaction.

Main characters in this research line: Mangano, Oliveri, Turriziani
