Spatial attention and working memory are popularly thought to be tightly coupled. Yet, distinct neural activity tracks attentional breadth and WM load.
In a new paper @jocn.bsky.social, we show that pupil size independently tracks breadth and load.

Incredible study by Raut et al.: by tracking a single measure (pupil size), you can model slow, large-scale dynamics in neuronal calcium, metabolism, and brain blood oxygen through a shared latent space! www.nature.com/articles/s41...

Cool new preprint by Damian. Among other findings: eye pupillometry, EEG & IEMs show that the premotor theory of attention can't be the full story: eye movements are associated with an additional, separable, spatially tuned process compared to covert attention, hundreds of ms before shifts happen.
Preparing overt eye movements and directing covert attention are neurally coupled. Yet, this coupling breaks down at the single-cell level. What about populations of neurons?
We show: EEG decoding dissociates preparatory overt from covert attention at the population level:
