Neuroscientists have explored the impacts of an emerging technique called transcranial ultrasound stimulation (TUS), and showed targeted treatments using it can induce significant changes in GABA (gamma-aminobutyric acid) concentration within the brain's posterior cingulate cortex in the hour following ultrasound treatment. They believe the study could pave the way towards treatment of conditions such as depression, addiction, or anxiety.

The targeted use of ultrasound technology can bring about significant changes in brain function that could pave the way towards treatment of conditions such as depression, addiction, or anxiety, a new study suggests.

However, focusing the beams through TUS can increase the pressure in the target region and change the way neurons communicate with one another., the research team say a study involving 24 healthy adults showed that TUS can induce significant changes in GABA concentration within the brain's posterior cingulate cortex in the hour following ultrasound treatment.

They say the study provides evidence that TUS works in humans and that changes in the brain are reversible, although much more work will need to be done before it can be applied in a clinical setting.
