Conference Theme: The Extracellular Matrix NichePoster Presentation: abstract no. P30Perineuronal chondroitin sulfate proteoglycan networks are implicated in restricting plasticity of the
mature CNS. Less is known of the impact of ligands associated with the perineuronal network (PN) in
the formative period of neural circuits. The emergence of negative geotaxis with postnatal maturation
of the vestibular circuitry for gravity detection offers a behavioral readout in tests for roles of the PN
and associated ligands in vestibular plasticity. Using postnatal rats as model, we found that negative
geotaxis was mature by postnatal day (P) 9, in correlation with ...postprin
