Teach your son to wait. Teach him that other people are as important as he is. Teach him to apologize and go back to the end of the line if he made an entitled decision. Teach him that girls and women deserve respect in *all* scenarios—not just during sex.

Rapid strengthening and reversal of hippocampal-neocortical interplay mediates human memory formation
Wang et al. demonstrate that hippocampal-neocortical interactions reorganize much faster than traditionally thought. Using multiday intracranial recordings in humans, they show that after just 1 day of learning, the temporal sequence of coupled ripples reverses, with the neocortex leading the hippocampus. This suggests an early neocortical dominance in memory formation.

Happy to announce this work has been published www.nature.com/articles/s44... People can view the same event and recall it differently. Here we asked if two participants recall events similarly, where in the brain do they share event representations both at encoding and recall?

Histology-based SWM microstructure intensity profile. Top: SWM sampling framework from 3D postmortem histology. The Laplacian field within the white matter domain was solved for each histological classified volume to sample 50 SWM surfaces, spanning from the GM/WM interface to 3 mm into the white matter. These surfaces were then mapped to each histological staining method, allowing the extraction of intensity profiles for each vertex across SWM depths. Bottom: Alterations in the intensity distributions of histological features across SWM depths. The GM/WM interface (0 mm) and 25 representative SWM surfaces (up to 3 mm into the white matter) are shown. The surfaces showing the greatest variation in SWM, from 0 to 1.8 mm into the white matter, were mapped onto the brain alongside the intensity profiles on the left.
