Brain Organoids Are Becoming Both Lab Models and Experimental Computers
↗
Brain organoids are serving dual roles as research models for human neural disease and as experimental substrates for biological computing.
Engineers must account for the biological variability and limited lifespan of living neural cultures when integrating them into hardware systems. Ethical guidelines and the lack of vascularization also constrain how large or complex these organoid-based computers can become.

Organoids derived from donor cells can replicate certain disease-related electrical patterns, offering a more human-relevant platform for drug screening.
When used as computing substrates, the cultures require electrode arrays for stimulation and readout, and their activity can be shaped by feedback-based training tasks.
Size is limited by diffusion of oxygen and nutrients, keeping most organoids under a few millimeters unless vascular support is added, which raises additional technical and ethical considerations.
