Researchers study human #attention using #microsaccades & N2pc #EEG marker, but does one cause the other? This study shows that microsaccades affect N2pc amplitude, but don't directly cause this attentional neural signature @PLOSBiology plos.io/4mB1Wwl

Microsaccades strongly modulate but do not cause the N2pc EEG marker of top-down covert and internal shifts of spatial attention. Trials were classified into “toward-microsaccade,” “away-microsaccade,” and “no microsaccade” classes based on the presence/absence and direction of microsaccades in the relevant predefined 150–400 ms time window. (a, e) Participant-specific proportions of trial classes during selection from perception (panel a) and working memory (panel e). (b, f) N2pc waveforms (contra vs. ipsilateral ERPs in PO7/8) for the three microsaccade-based trial classes. Shading indicates ±1 SEM calculated across participants (n = 23). Colored horizontal lines in the time course plots indicate significant temporal clusters (cluster-based permutation). (c, g) N2pc amplitudes in the three microsaccade trial classes extracted over the predefined 200–300 ms N2pc time window. The bar graphs show mean values, with error bars indicating ±1 SEM calculated across participants (n = 23). The stars above the bars indicate that N2pc amplitude for that specific trial class is significantly different from zero (P < 0.05). (d, h) N2pc topographies across trial classes plotted as contralateral vs. ipsilateral activity.

Our paper, "Stimulus representations in visual cortex shaped by spatial attention and microsaccades" was just published in the Proceedings of the National Academy of Sciences (PNAS).

New preprint paper from the Desimone gang! Hopefully, the first of a few from us this year.

Work done with @elowet, Bruno Gomes, and of course the boss!

New preprint out! With @psy_michel and @cognikobusch we show that alpha oscillations do not track the full course of exogenous attention.
