Multi-spectral oscillatory dynamics serving directed and divided attention.

ABSTRACT: Attention-related amplification of neural representations of external stimuli has been well documented in the visual domain, however, research concerning the oscillatory dynamics of such directed attention is relatively sparse in humans. Specifically, it is unknown which spectrally-specific neural responses are mainly impacted by the direction and division of attention, as well as whether the effects of attention on these oscillations are spatially disparate. In this study, we use magnetoencephalography and a visual-somatosensory oddball task to investigate the whole-brain oscillatory dynamics of directed (Experiment 1; N ​= ​26) and divided (Experiment 2; N ​= ​34) visual attention. Sensor-level data were transformed into the time-frequency domain and significant responses from baseline w
