Noninvasive control of neural circuits:
Acoustically Targeted Chemogenetics (ATAC)

Treatment of neurological and neuropsychiatric diseases requires control of the right brain cells in the right brain region at the right time. Existing technologies capable of doing so require invasive techniques, such as neurosurgery and placement of permanent intracranial implants, which carry significant risks including damage to brain tissues, infection, bleeding, and other complications. Acoustically Targeted Chemogenetics (ATAC) aims to improve the safety, precision, and cost of treatment of such diseases through noninvasive and non-surgical gene therapy that is capable of targeting the right brain cells in the right regions of the brain at the right time.
