The reorganized stereotypical pattern in Arc laminar redistribution appeared after remote WM recall. The probe tests on a WM task learned 1 month ago induced more frequent increases in Arc mRNA fractions in the upper layers L4 and L2/3 as compared to the lower layers. However the decreases in Arc fractions in L6 characteristic for recent recall became less frequent within the parietal association (A), V1 (B) and M1 (C) cortices at the 1-month interval. (D) A summary plot depicts frequencies of the segments that displayed redistribution in Arc laminar fractions after the remote memory recall.
