- Reposted by Eric DenovellisThe New York Times piece today about US science is terrible and wrong—in many ways. I could write a whole article about this, but as one example: “To close observers, the original crisis began well before any of this…” No. I’m a close observer of science, and this is incorrect.

- Reposted by Eric DenovellisI’m excited to share my final co-first author paper from my postdoc in Dan Dombeck's lab! We explored how behavior, senses, and neurons influence how much information in the brain changes over time. www.nature.com/articles/s41... #science #research #neuroscience #hippocampus #placecells
- Reposted by Eric DenovellisSuper cool results, and another evidence that theta sweeps are more about (sequential 😉) prediction following behavior, which happens to be rhythmic in the rodent.
- Our study is out in Nature! Using wireless Neuropixels we recorded hippocampal activity in freely flying bats and uncovered replay and theta(less) sweeps, revealing striking differences from classic rodent models. 👉 www.nature.com/articles/s41...
