Recently, a third germinal layer, the subcallosal zone has been identified supporting the generation of oligodendrocytes in the adult brain. We have previously described a proliferative role for neuropeptide Y on precursors in the dentate gyrus, caudal subventricular zone and subcallosal zone under basal conditions and in the dentate gyrus after seizures. Here we sought to determine a role for neuropeptide Y in seizure-induced proliferation in the subcallosal niche. Using the chemoconvulsant kainate and neuropeptide Y−/− mice with controls, we show an effect of neuropeptide Y on basal proliferation and demonstrate a significant reduction in seizure-induced proliferation in the subcallosal zone. Erratum A typographical error was published in the article ‘NPY mediates basal and seizure-induced proliferation in the subcallosal zone’ by Alexandra Laskowski, Owain W. Howell, Alexander A. Sosunov, Guy McKhann and William P. Gray  which appeared on pp. 1005–1008 of Neuroreport, Volume 18, Issue 10. The author Alexander A. Sosuov should have appeared as Alexander A. Sosunov. The online version of the article has now been corrected. We apologise for this error. NeuroReport. 18(12):1303, August 6, 2007. © 2007 Lippincott Williams & Wilkins, Inc.
