Sleep isn't downtime for memory. It's the shift when the work gets done.
Our new paper shows that fragmenting sleep in mice, without shortening it, still measurably weakens how the hippocampus consolidates what was learned that day. Total hours slept looked normal. The consolidation did not.
The practical read: studies that track sleep duration alone may be missing the variable that matters.
Full paper linked below. Happy to talk methods with anyone working on this.
