Summary: Shrinkage of the brain can be reversed with people with Alzheimer’s disease by jolting the degenerating tissue with electrical impulses. More than that, doing this reduces physical downfall associated with the disease. Andres Lozaho at Toronto western hospital in Ontario and his team put electrodes into the brains of six people, who had been diagnosed with Alzheimer’s disease at least a year earlier. They paced them next to the fornix, which is a bundle of newtons that carries signals to and from hippocampus. Then, they delivered tiny pulses of electricity 130 times a second. Later tests showed that the reduced use of glucose by the temporal lobe and posterior had been reversed in all six people.

Critique: I think that this was very good because it is a cure for Alzheimer’s. More people get to live longer.

Impact: The impact this has on the world is very positive because more people are surviving and living longer.
