In the article titled “Ketamine administration reverses corticosterone-induced alterations in excitatory and inhibitory transmission in the rat dorsal raphe nucleus” [1], there was an error in Figures 2 and 3. Figures 2 and 3 images were swapped. These errors occurred during the production process. The correct figures are as follows.

Single ketamine injection reverses the effect of repeated corticosterone administration on DRN glutamatergic transmission. (a) Sample recordings from representative neurons in slices prepared from animals treated with Tween+NaCl (upper left trace), Tween+Ket (lower left trace), Cort+NaCl (upper right trace), and Cort+Ket (lower right trace). (b1) Cumulative probability plots of interevent intervals of sEPSCs recorded from individual representative neurons from all four groups of rats. (b2) Cumulative probability plots of amplitudes of sEPSCs recorded from individual representative neurons. (c1) Summary graph showing the mean frequency (±SEM) of sEPSCs recorded from all neurons from the Tween+NaCl-, Tween+Ket-, Cort+NaCl-, and Cort+Ket-treated rats. . (c2) Mean amplitudes (±SEM) of sEPSCs recorded from all neurons divided into the four investigated groups of animals (labels as in (c1)).
