There's a great talk by Juan Gallego on how low-dimensional #NeuralManifolds arise from biological constraints, remain invariant across states and inputs, and support cross-animal alignment. Examples span #HeadDirection rings, #gridcell tori, #MotorCortex prep vs movement, striatal timing dynamics, and C. elegans #behavior loops. Cool talk as it shows how #manifold-level structure can generalize across tasks and organisms.

🧠 New study by Asumbisa, Peyrache & Trenholm (2025): Stereo #olfaction underlies stable #coding of #HeadDirection in blind mice. Inhibiting #odor detection in just one nostril, or removing the spatial difference in airflow, disrupts head direction cell tuning and impairs mice’s spatial orientation → stereo smell is essential for using olfactory cues to form a stable, #allocentric sense of direction.
