A Fruit Fly’s Brain Has Been Uploaded — and It Behaves Like a Fruit Fly

Researchers (via Eon Systems) report uploading a mapped fruit‑fly brain into a digital environment where its neurons respond to virtual sensors and produce fly‑like behavior; the work is not yet peer‑reviewed but claims active, not merely simulated, neural responses. This is a concrete step from connectome mapping toward substrate‑independent neural function. If validated, it marks a technical milestone on the path toward more complex brain emulations. — Demonstrations of active biological brain uploads shift debates from hypothetical ethics and law to immediate questions about regulation, research transparency, and what counts as consciousness or personhood.
