Paul Allen, who helped co-found Microsoft alongside Bill Gates in 1975, has donated $300 million to The Allen Institute for Brain Science, based in Seattle. The Allen Institute is launching a 10-year plan to expand research into the inner workings of the brain and how to best treat brain-related disorders, and Allen's $300 million contribution will reportedly help sustain this program for the first four years.
