The paper develops a method for large-scale volumetric calcium imaging in marmoset brains, revealing fine-grain tuning properties and columnar organization in auditory and visual cortices.

The paper identifies a transcriptional continuum in parvalbumin interneurons based on perineuronal net status, linking it to fast-spiking specialization and plasticity.

This paper investigates the role of Aggrecan in PV+ interneurons by creating a conditional knockout model and finds that its absence does not affect electrophysiological properties but alters behavioral strategies and anxiety levels.

The paper develops and tests new viral vectors for systemic and local delivery of GECIs to enable brain-wide calcium imaging without transgenic mouse lines.
