Optogenetic interrogation of the lateral-line sensory system reveals mechanisms of pattern separation in the zebrafish brain

The paper uses optogenetic stimulation and calcium imaging in zebrafish to study how sensory inputs from neuromasts are processed in the brain, revealing nonlinear integration and sparse neuronal representations.

Depicting pseudotime-lagged causality across single-cell trajectories for accurate gene-regulatory inference

This paper introduces DELAY, a deep learning method for inferring gene-regulatory networks from single-cell data, showing improved performance over existing methods in identifying causal relationships.
