����Ӱҵ’s biomedical engineering professor Jacek Dmochowski uses ultrasound and lasers to stimulate the brain treating mental disorders as well as physical and mental wellness during deep space exploration missions. His research just got a boost from the ’s and the , in partnership with .

“The brain is sensitive to mechanical forces, and we think that we will be able to make the brain more or less active by sending in a wave of ultrasound applied to the head,” said Dmochowski about his NIH grant. “In particular, we are interested in altering the pattern of brain waves that have been shown to be modified during disorders such as schizophrenia, depression, and obsessive-compulsive disorder.”

By changing the abnormal patterns of brain oscillations through ultrasound, it will treat the symptoms and potentially the root of the disease.  The major advantage of brain stimulation versus medication is that it can be applied just to one area of the brain, as opposed to drugs, which are generally taken orally and then delivered to all parts of the nervous system, causing unwanted side effects.

His mentor Elisa Konofagou, a professor of biomedical engineering at Columbia University, oversees Dmochowski during the two-year NIH grant. As a junior investigator, Dmochowski will benefit from Konofagou, whose expertise is in ultrasound. The grant is for $300,000.

Dmochowski’s two-year TRISH grant will allow him to test the possibility of using lasers to increase energy metabolism in the brain. By stimulating the brain with lasers, it will accelerate energy metabolism and enhance cognitive function in spaceflight for astronauts. The grant is for $800,000.

“All cells, including those in the brain, require energy in the form of ATP to carry out essential functions,” said Dmochowski. “This is an important problem during deep space missions, which last 18-24 months, because a number of negative health consequences, including those affecting cognition, have been reported.”
