Thanks to Erica Tobolski for sending this one in: scientists have discovered that shed light on the "dissociative" experience many have on drugs including ketamine and PCP, the experience in which a person "feels separated from their own thoughts, feelings and body." The research team was not only able to associate this dissociation in 1–3-Hz rhythm in layer 5 neurons of the retrosplenial cortex, but were able to stimulate dissociation in both mice and humans!

How the brain stores auditory memories (see chapter 10) may involve the same areas of the brain explored in this study. See for an overview.
