Neurons in a mouse brain are shown here in magenta. The lab of Associate Professor Sreekanth Chalasani made some neurons (white) express the protein TRPA1 so they can be activated by ultrasound in a technique known as “sonogenetics.” Sonogenetics is a powerful, non-invasive tool that allows researchers to control brain cells with sound waves. Chalasani coined the term and pioneered this technology, which could one day be used to treat neurological conditions such as epilepsy and Parkinson’s disease.
