A corrigendum on
Calcium in Kenyon Cell Somata as a Substrate for an Olfactory Sensory Memory in Drosophila
by Lüdke, A., Raiser, G., Nehrkorn, J., Herz, A. V. M., Galizia, C. G., and Szyszka, P. (2018). Front. Cell. Neurosci. 12:128. doi: 10.3389/fncel.2018.00128
In the original article, we did not indicate the number of analyzed animals and glomeruli/somata/ROIs. We provide this information below:
Figures 2, 3, and 7:
ORN axons: N = 9 flies, n = 85 glomeruli (glomeruli per fly: 11, 11, 10, 5, 10, 10, 7, 10, 11)
PN dendrites: N = 10 flies, n = 88 glomeruli (glomeruli per fly: 9, 5, 8, 9, 11, 10, 10, 12, 7, 7)
[In Figures 3C–F the N and n for the odors EACE (N = 3, n = 22) and MCH (N = 7, n = 66) in PN dendrites is lower, since these odors were used alternately].
Figure 4 and Supplementary Figure S2:
(same flies as above, with one additional fly and thirteen additional glomeruli in ORN axons):
ORN axons: N = 10 flies, n = 98 glomeruli (glom. per fly: 11, 11, 10, 6, 10, 10, 10, 9, 10, 11)
PN dendrites: N = 10 flies, n = 88 glomeruli (glom. per fly: 9, 5, 8, 9, 11, 10, 10, 12, 7, 7)
Figures 5, 6:
PN somata: N = 10 flies, n = 108 somata (somata per fly: 18, 15, 13, 5, 13, 10, 9, 9, 12, 4)
KC dendrites: N = 6 flies, n = 343 ROIs (ROIs per fly: 57, 35, 31, 60, 84, 76)
KC somata: N = 9 flies, n = 339 somata (somata per fly: 47, 28, 26, 52, 44, 23, 3, 55, 61)
(In Figures 6C–F and Supplementary Figure S3 the N and n in the PN somata and KC somata matrices vary for each odor pair, because not every odor was analyzable in every fly. PN somata: N = 4–10 flies, n = 47–108 somata; KC somata: N = 5–8 flies, n = 217–313 somata).
Figure 7:
PN somata: N = 2 flies, n = 25 somata (somata per fly: 13, 12)
KC dendrites: N = 6 flies, n = 343 ROIs (ROIs per fly: 57, 35, 31, 60, 84, 76)
KC somata: N = 5 flies, n = 217 somata (somata per fly: 47, 28, 26, 55, 61)
(Note that for the SVM we could only use flies with complete data for the same set of odorants (ButL, AceA, ProL, ProA, MO),
hence the lower N in PN somata and KC somata).
In the original article the following reference was incorrectly cited as “unpublished”. The corrected reference appears below:
Betkiewicz, R. L., Lindner, B., and Nawrot, M. P. (2017). Circuit and cellular mechanisms facilitate the transformation from dense to sparse coding in the insect olfactory system. BioRxiv [Preprint]. doi: 10.1101/240671
We apologize for this missing information and emphasize that this does not change the scientific conclusions of the article in any way.
The original article has been updated.
