I find this article by Ferro just out in nature communication https://rdcu.be/dOzT2 is an interesting intersection between value-based decision-making, embodied cognition/active vision, and memory #reactivation or #reinstatement. Looking is doing some heavy lifting. And lookie there, I didn't even mention the #orbitofrontalcortex recordings they did!

It caught my eye (sorry) b/c some of the scanpath analysis our lab's done in the past suggests that prior to looking at a remembered, rewarded visual target, there's an uptick in #hippocampal #ripples (Leonard et al., Current Biol 2017), which are thought to signal the underlying reactivation of task-relevant activity patterns. And of course, there's work by a number of groups on memory guidance to rewarding/goal targets, that rely on hippocampal function. Ours based on an MTL amnesic: Yoo, et al., (2020). Long-term memory and hippocampal function support predictive gaze control during goal-directed search. Journal of Vision, https://doi.org/10.1167/jov.20.5.10 following from Chau et al., 2011, and the changes in scanpaths and pupil responses of aging adults and people with Alzheimer's disease, too: Dragan, M. C.,et al., (2017). Behavioural Brain Research, https://doi.org/10.1016/j.bbr.2016.09.014

Where we choose to look says so much: see e.g. Kragel/Voss; Castelhano/Henderson, Wynn/Buchsbaum/Olsen/Ryan esp what Jordana Wynn followed up with on the scanpath reinstatements suggests a really intertwined relationship between memory, eye movements, and learning/decisions about goals. (forgive that I'm missing many others and pls add below!)

TL;DR The foraging decision-making folks and the memory-guided vision folks need to be increasingly up in each other's business.

COVID isn’t just infecting you—it could be reactivating viruses that have been dormant in your body for years

“Long COVID” in some may not be an entirely new entity, researchers say.
