NEUROSCIENCE, PSYCHOLOGICAL AND COGNITIVE SCIENCES Correction for “Cortical ensembles selective for context,” by Jordan P. Hamm, Yuriy Shymkiv, Shuting Han, Weijian Yang, and Rafael Yuste, which published April 2, 2021; 10.1073/pnas.2026179118 (Proc. Natl. Acad. Sci. U.S.A. 118, e2026179118).
The authors note that on page 2, left column, first full paragraph, line 26, “n = 841 neurons, about 51% of total cells” should instead appear as “n = 611, about 74% of scored cells.”
On page 6, right column, first full paragraph, line 2, “We first analyzed responses from layers 2 through 5: 150 to 230 μm (layer 2; 610 out of 2,462 cells responsive, 25%), 270 to 310 μm (layer 3; 451/1,669, 27%), 370 to 410 μm (layer 4; 529/1,580, 33%), and 450 to 530 μm (layer 5; 698/1,449, 48%)” should instead appear as “We first analyzed responses from layers 2 through 5: 150 to 230 μm (layer 2; 563 out of 2,462 cells responsive, 22%), 270 to 310 μm (layer 3; 398/1,669, 24%), 370 to 410 μm (layer 4; 454/1,580, 29%), and 450 to 530 μm (layer 5; 596/1,449, 41%).”
On page 7, left column, third full paragraph, line 8, “A total of 534 PFC ROIs (out of 808 recorded)” should instead appear as “A total of 312 PFC ROIs (out of 404 unique ROIs) yielding 534 separate responses to stimuli (from 808 possible).”
On page 11, left column, fourth full paragraph, line 9, “Only responses to one stimulus orientation were considered for each cell (i.e., the orientation with greater magnitude).” should instead appear as “Most neurons did not show above threshold responses to both an orientation and its orthogonal counterpart (<25% of cells). If present, we included both neural responses in our analyses. Alternatively, if only responses to one stimulus orientation were considered for each cell (i.e., the orientation evoking greatest average magnitude), this did not alter any of the main effects or patterns of results. Thus, our results reflect all available above threshold responses.”
