The paper develops a genetically encoded voltage indicator to measure subthreshold voltage dynamics in neurons, revealing electrical diversity and local computation.

This study introduces a new microscopy technique to track neocortical activity with high spatial and temporal resolution, revealing fundamental dynamical elements and their properties across different neural activity regimes.

The paper identifies directional elements in brain dynamics that encode causal control hierarchies and show robustness to neural state manipulations.
