Patient-derived brain organoids have become powerful models for studying neurological disorders, but understanding how those models function—not just how they look—remains a major challenge.
In the second installment of The SomaFocus Series, Dr. Flora Vaccarino and Dr. Riya Rauthan from Yale University shared how their lab is using patient-derived brain organoids and functional electrophysiology to investigate Tourette syndrome, revealing disease-relevant neural activity that cannot be captured through structural analysis alone.

Key Takeaways from the Webinar
Functional phenotypes provide insights beyond morphology.
While organoids can replicate many aspects of human brain development, differences between healthy and disease models are not always apparent through imaging or molecular analysis alone. The webinar demonstrated how electrophysiological recordings reveal alterations in neural network behavior that help distinguish disease phenotypes.
Patient-derived organoids reveal circuit-level dysfunction.
Using iPSC-derived basal ganglia organoids from patients with Tourette syndrome, the Yale team examined how neural circuits develop and communicate. Rather than focusing solely on cellular composition, the researchers investigated how networks function over time, providing a more complete understanding of disease biology.
Recording inside intact organoids matters.
Because neural circuits develop throughout the three-dimensional volume of an organoid, capturing activity only at the surface can leave important information undiscovered. SomaFocus enables automated functional recordings from within intact organoids, allowing researchers to measure single-neuron spiking and local field potentials across multiple depths without sectioning or plating the tissue.

Functional electrophysiology strengthens disease models.
The discussion highlighted how integrating electrophysiology with transcriptomics, imaging, and other molecular assays creates a more comprehensive picture of disease. Functional measurements provide an additional layer of evidence that can improve disease model validation and potentially strengthen drug discovery workflows.
Why This Matters
As brain organoid models become increasingly sophisticated, the questions researchers ask are evolving from "Did we build the right cells?" to "Are the neural circuits functioning as they should?"
Answering those questions requires tools capable of measuring real-time neural activity inside intact 3D tissues. Functional electrophysiology is becoming an essential component of organoid research, helping scientists identify disease-relevant phenotypes, evaluate therapeutic responses, and better understand neural circuit development.
