This isn't about species differences!
When bats flew in a short tunnel, replays covered much larger fractions of space.
And key replay features — duration, compression ratio, co-occurrence with SW-ripples — were similar to rodents.
It’s the environment size that changes the game!

This fragmentation wasn’t random:
🧠 Replays were biased toward meaningful events (landings, crossovers with other bats).
🔥 Suggests selective memory consolidation or chunking of memory.

We recorded CA1 activity in bats flying in a 200m long tunnel🦇
💡Replays were short, fragmented snippets—covering only ~6% of the full flight experience.
Even though the bats flew continuously the entire long tunnel, replays during sleep or pauses recapitulated only chunks.

Previous studies (in rodents in small environments) showed that the hippocampus replays entire past trajectories during rest.
But what happens when animals navigate natural-scale environments? 🏞️
