The superposition of these two studies — both incredible — reflect a snapshot of "one big thing" systems neuroscience has yet to resolve. In mice: 1. Task-related signals are everywhere. 2. Absent large swaths of "everywhere," suprisingly sophisticated learning & behavior remains.

Textbook: tracking position during navigation is primarily the job of the hippocampus. Recent findings suggest a more complicated story. Recording >20k neurons brainwide, we indeed find spatial representations in every region! With @kenneth-harris.bsky.social and @carandinilab.net

This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!

Excited to release the SPOT grid: a new image set that factorially crosses scene-object & texture-pattern pairings. We hope these stimuli will be useful to researchers aiming to (partially) disentangle the contributions of lower- and higher-level visual features to behavior & brain activity. 1/
8x8 grid depicting the approach to stimulus creation. Feature pairs are on the axes and images are in the cells. The x-axis represents the high-level feature pairs: setting (green) and object (teal). For example, the first column of images all depict “truck” (object) in “field” (setting) rendered in various textures and patterns. The y-axis represents low-level feature pairs: texture (blue) and pattern (purple). For example, the first row of images all depict different objects and settings rendered as if drawn with crayon (texture) and containing large horizontal edges (pattern).

Greeted an old Dutch couple at the hotel. We spot a mess on the ground. Gentleman, without hesitation: “You did this, right?" Me: "We do not do such a thing." His wife with elite improv: “You guys just swim on it.” It's fun to experience the coexistence of the best bike system and improvisation.

I wrote an article earlier in the week arguing that we need to give junior researchers more independence earlier, and this should be our focus, not moonshot mega projects led by senior researchers. I was surprised how much agreement I'm seeing. So next question: how do we do this?
