Impact statement
Although the cortical generators of steady state visual evoked responses
as recorded by EEG or MEG (SSVEPs or SSVEFs, respectively) have been
described in humans, how these generators are involved in the modulation
of these evoked oscillatory responses by spatial attention is less
known. Here, we describe how distinct sub-divisions of the early human
visual cortex contribute differently to the modulation of SSVEFs by
spatial attention.
