Awesome work by @matteoguardamagna.bsky.social et al: The geometry of the #gridcell system seems to come online before #behavior does. Toroidal #manifolds in #rat #MEC appear at P10, align progressively with real space only after pups begin to explore. Strong case for preconfigured spatial circuits!
The #Moser researchers recorded thousands of #GridCell neurons in rat pups with #Neuropixels.
They found that key navigation network-activity structures - grid cell torus map 🍩 & head direction ring ⭕️ - emerge days before pups open their eyes, ears or start walking. (2:5)
Is spatial navigation innate 🧠? Using #NeuroPixels we show that the #torus 🍩 underlying the #GridCell map exists already on day 10 in rats — before pups open eyes and ears and before they start upright walking. 🧵1:4
