Launched in 2023, Imaging Neuroscience is now firmly established, with full indexing (PubMed, etc.) and 700 papers to date. We're very happy to announce that we are able to reduce the APC to $1400. Huge thanks to all authors, reviewers, editorial team+board, and MIT Press.

Re the Tononi paper: Both Tononi’s IIT (phi) and Friston’s FEP start from fundamental, axiomatic, and debatable assumptions. These assumptions are generally made without any humility. This logic allows them to make exceptionally broad claims. Which contributes to my unease about them.

⚡️ Excited to introduce ZAPBench, our #ICLR2025 spotlight: The Zebrafish Activity Prediction Benchmark measures progress in predicting neural activity within an entire vertebrate brain (70k+ neurons!) Explore interactive visualizations, datasets, code + paper: google-research.github.io/zapbench 🧠🧪

ZAPBench

ZAPBench evaluates how well different models can predict the activity of over 70,000 neurons in a novel larval zebrafish dataset.

One of the NIMH PIs whose name is the termination list: Sooyhun Lee, whose lab just published this beautiful @nature.com paper (that has received too little press because comms at NIH are down). Read! Cite! www.nature.com/articles/s41...

Brain-wide presynaptic networks of functionally distinct cortical neurons - Nature

Behavioural-state-dependent pyramidal neurons have a distinct pattern of long-range glutamatergic inputs, with a larger proportion of thalamic versus motor cortex inputs compared with non-behavio...

Should you stick to your goal, try something else, or give up? Your median raphe nucleus in the brainstem knows and will decide for you 😉. First foray of my lab into foraging, behavioural strategies and exploration. Amazing work from the one and only Mehran Ahmadlou: www.nature.com/articles/s41...

A subcortical switchboard for perseverative, exploratory and disengaged states - Nature

Behavioural experiments in mice demonstrate that GABAergic (γ-aminobutyric acid-expressing), glutamatergic and serotonergic neurons in the median raphe nucleus have distinct and complementary function...

New work accepted to #AISTATS2025 ✨ We developed a new explainable AI method to better understand time-series data. We can map back inputs (neurons) to their latent space. Basically merging #CEBRA with measuring the individual neurons contribution over time arxiv.org/abs/2502.12977

Two cool papers on the HPC out today in @nature.com: 1. Replay during non-REM sleep switches between prioritizing recent versus remote memories: www.nature.com/articles/s41... 2. All optical obs. of synaptic plasticity rules during place field formation: www.nature.com/articles/s41... 🧠📈 🧪

Sleep microstructure organizes memory replay - Nature

The temporal microstructure of the brain can multiplex distinct cognitive processes during sleep to support continuous learning.
