Current strategies to remove PNN are long-lasting, invasive, and trigger neuropsychiatric symptoms. Here, we apply repeated anesthetic ketamine as a method with minimal behavioral effect. We find that this paradigm strongly reduces PNN coating in the healthy adult brain and promotes juvenile-like plasticity. Microglia are critically involved in PNN loss because they engage with parvalbumin-positive neurons in their defined cortical layer. We identify external 60-Hz light-flickering entrainment to recapitulate microglia-mediated PNN removal. Importantly, 40-Hz frequency, which is known to remove amyloid plaques, does not induce PNN loss, suggesting microglia might functionally tune to distinct brain frequencies. Thus, our 60-Hz light-entrainment strategy provides an alternative form of PNN intervention in the healthy adult brain."}],"department":[{"_id":"SaSi"}],"volume":36,"intvolume":"        36","acknowledged_ssus":[{"_id":"Bio"},{"_id":"PreCl"}],"year":"2021","isi":1,"acknowledgement":"We thank the scientific service units at IST Austria, especially the IST bioimaging facility, the preclinical facility, and, specifically, Michael Schunn and Sonja Haslinger for excellent support; Plexxikon for the PLX food; the Csicsvari group for advice and equipment for in vivo recording; Jürgen Siegert for the light-entrainment design; Marco Benevento, Soledad Gonzalo Cogno, Pat King, and all Siegert group members for constant feedback on the project and manuscript; Lorena Pantano (PILM Bioinformatics Core) for assisting with sample-size determination for OD plasticity experiments; and Ana Morello from MIT for technical assistance with VEPs recordings.
