The research is focused on the hippocampus, where short-term memories are solidified into long-term ones by the movement of electrical signals through neurons.
Theodore
Berger, a biomedical engineer and neuroscientist at the University of
Southern California in Los Angeles, envisions a day in
the not too distant future when a patient with severe memory loss can get help from an electronic implant.
In people
whose brains have suffered damage from Alzheimer’s, stroke, or injury,
disrupted neuronal networks often prevent long-term memories from
forming. For more than two decades, Berger has designed silicon chips to
mimic the signal processing that those neurons do when they’re
functioning properly—the work that allows us to recall experiences and
knowledge for more than a minute. Ultimately, Berger wants to restore
the ability to create long-term memories by implanting chips like these
in the brain.
