Mapping brain-region connections in mini human brain models with light-guided probes
Dissecting inter-region communication in human organoid models with dual-color optogenetic probes
This project develops tiny light-based tools to control and record activity in mini human brain tissues to learn how brain circuits involved in autism communicate.

What this research studies
If I'm following this research, scientists will grow 3D "mini-brains" from human cells that model different brain regions. They'll build tiny dual-color light probes combined with electrodes to turn specific cells on or off while recording signals across regions in real time. By using two colors they can control different cell types separately and map how signals travel between compartments. This work aims to show how connections in organoid models of autism form or go awry.
Who could benefit from this research
Good fit: Ideal participants would be people with autism or family members willing to donate cells (for example blood or skin samples) so researchers can make patient-derived mini-brains.
Not a fit: People seeking immediate clinical treatments should not expect direct benefit because this is lab-based basic research rather than a patient treatment trial.
Why it matters
Potential benefit: If successful, this could reveal circuit-level changes in autism and help guide future targeted treatments or diagnostics.
How similar studies have performed: Optogenetics and human organoid models have provided useful lab insights, but combining dual-color optogenetic control with high-density recording in 3D organoids is relatively new and exploratory.
