Developmental cell death of interneurons and oligodendroglia is required for cognitive flexibility in mice
Programmed cell death (PCD) is essential for regulating cell homeostasis in the developing brain. Cell populations that undergo massive PCD in the cortex include the first wave of oligodendrocyte precursor cells (firstOPCs) and most of GABAergic interneurons, which die postnatally within the same period. Furthermore, firstOPCs and most interneurons share common embryonic origins. Here we investigated how PCD of both firstOPCs and their lineage-related interneurons impact behavior and cortical networks. We used behavioral assays, patch-clamp recordings and immunostainings in two mouse models in
