If I understand the research correctly, they have created viral code which runs the moral equivalent of update brain set syn_strength ×= 1.1 where src_region=med_prefront_ctx and dst_region=dorsal_raphae in the brains of mice without affecting any surrounding tissue. Pretty impressive. Or actually, since the update remained dormant until activated, more like a trigger: create trigger fix_brain update brain ... when brain_juice_z > 0.8
