What about #placefields and #thetasequences?
✅ Place fields - intact
✅ Population level - space could be decoded equally well in control versus targeted animals [e.g. video in 1/]
BUT
❌ Pairwise corr. b/w pyramidal neurons were impaired
❌ ~8Hz rhythmicity of theta sequences was impaired

See how much #dendritic geometry matters for #SpatialCoding: clustered excitatory inputs on #CA1 #dendrites can support stable #PlaceFields with fewer active #synapses, by engaging local nonlinearities and Ca2+ signaling:
