abstract：:Brain activity was studied with fMRI and steady-state visual evoked potentials (SSVEPs) in separate sessions as subjects attended to letter sequences in either the right or left visual field. The two letter sequences were superimposed on small square backgrounds that flickered at 8.6 and 12.0 Hz, respectively, and eli...
