Hierarchical Bayesian modeling of multiregion brain cell count data
Bayesian hierarchical models offer powerful statistical tools for neuroscientists to analyze whole-brain cell count data, as demonstrated here using two example datasets from different laboratories.

Brains have many pathways / subnetworks but which principles underlie their formation?
In our #NeurIPS paper lead by Jack Cook we identify biologically relevant inductive biases that create pathways in brain-like Mixture-of-Experts models🧵

Exploiting heterogeneous delays for efficient computation in low-bit neural networks
Neural networks rely on learning synaptic weights. However, this overlooks other neural parameters that can also be learned and may be utilized by the brain. One such parameter is the delay: the brain...

In the end, even basic brain connectivity is different between rodents and primates, with primates having more specialized, sparsely connected brain regions.

A cool summary of our paper!
A core function of cortex is predicting what happens next given the world's state.
This recent paper from Oxford shows how cortical layers may use a delay trick to learn to predict.
A simple illustration can explain the idea.
