Associated to the scholarship:16/04258-0 - Attention and expectation effects on neural processing, BP.DR


Attention is fundamental to optimize the computational capacity of a biological system. Several studies have shown that humans and non-humans animals process targets more efficiently when they are presented at expected moments. A possible mechanism for such facilitation is the pre-activation of receptive fields at the relevant moments. However, the nature of this pre-activation remains largely unknown. Recent studies have developed new brain state decoding methods using EEG/MEG responses to uncover how attended and ignored information are processed. In the present study, we aim to use such methods to investigate the mechanisms and the effects of allocating attention to a sensory modality (vision or audition) and to instants in time.
