What resolves this contention: The traditional view of exclusive PV identity of axo-axonic cells is complicated by evidence that somatostatin neurons can also form AIS-targeting synapses, and that PV cell classification is more complex than the canonical three types / Chandelier cells mediate axo-axonic inhibition via PV-positive terminals with GABA-A alpha1 receptors postsynaptically / All three major PV classes (basket, axo-axonic, bistratified) show functionally distinct behaviors during fast oscillations
