Data Stored in Live Neurons 100

Posted by Zonk from the literal-wetware dept.
Light Licker writes "Israeli researchers have created artificial memories for the first time — in a tangle of neurons growing in the lab. Using a specific chemical they could add to the pattern of impulses in a network of the nerve cells. 'Many believe that complex patterns of neuronal firing are templates for memory, which the brain uses when storing information. Imprinting such "memories" on artificial neural networks provides a potential way to develop cyborg chips, says Ben-Jacob. These would be useful for monitoring biological systems like the brain and blood since, being human, they would respond to the same chemicals.' The new pattern lasted two days — good enough for biological RAM?"

    • Depends on what you mean by "brainwashing".

      A data storage system based on live neurons doesn't necessarily mean you'll become the automaton of an evil 1984 society. Film-based sci-fi cyborg scenarios are way beyond reach for the time being.

      You used a word with negative connotations, but that's how many electronic memory devices work. They start with a full set of connections and are programmed by deleting all the unwanted connections.

      In old-style PROMs (programmable read-only memories) the connections were metallic fuses that were burned by a pulse of current. Then came EPROMs (eraseable programmable read-only memories) where the connections could be restored by bathing
