We propose that behavioral alignment is a general principle that should be considered when understanding sensorimotor representations.

Have you ever wondered how the brain should represent the sensory world in order to generate behavior? Read our new preprint: work by Shuhong Huang shuhonghuang.bsky.social with our long-standing collaborator James Fitzgerald at Northwestern.
Normative theories such as efficient coding have constrained representations from the sensory input side. Here, we propose that representations to sensory stimuli should be similar when they elicit similar behaviors.
We check this behavioral alignment principle by measuring behavior in larval zebrafish and showing that we can predictively account for visual encoding throughout the brain: population codes represent visual stimuli according to the optomotor responses they elicit.
New paper alert! 🚨
We found that the brain's compass is remarkably stable at two scales
1️⃣ the system maintains its internal organization for weeks
2️⃣ It "remembers" its orientation for weeks, even after a single visit
This may be key to how the brain aligns its other maps.
