Erratum: For the article “‘Slow Activity Transients’ in Infant Rat Visual Cortex: A Spreading Synchronous Oscillation Patterned by Retinal Waves” by Matthew T. Colonnese and Rustem Khazipov, which appeared on pages 4325–4337 of the March 24, 2010, issue, the authors would like to issue the following correction: Our paper incorrectly stated that infra-slow activity transients have not been described in animal models and implied that no animal models of human SATs had been proposed. In fact, using wide-band recording methods, Seelke and Blumberg (2008) [Seelke AMH, Blumberg MS (2008) The microstructure of active and quiet sleep as cortical delta activity emerges in infant rats. Sleep 31:691–699] described SATs in the parietal cortex of P9–P13 rats that they defined as “discrete, high-amplitude, cortical events with a duration of approximately 5 seconds,” though absent consistent rapid oscillations. We apologize for this oversight. Published online after our paper's acceptance, Seelke and Blumberg (2010) [Seelke AMH, Blumberg MS (2010) Developmental appearance and disappearance of cortical events and oscillations in infant rats. Brain Res 1324:34–42], recording from the frontal, parietal, and occipital lobes of P5–P13 rats, also reported SATs, some of which contained high-frequency embedded activity and some of which did not.
