A study recently published in the journal Frontiers in Human Neuroscience suggests that targeting a region of the prefrontal cortex with transcranial focused ultrasound (tFUS) — a new ultrasound technique — may temporarily elevate mood.
The findings could both open the door to further mood-enhancing techniques and support further research into consciousness.
tFUS is a developing technique that allows researchers to affect the pattern of a person’s brain waves. Influencing brain waves in this way can generate different cognitive effects.
Other techniques for changing brain waves include transcranial magnetic stimulation and transcranial direct current stimulation. tFUS has a number of advantages over these methods, primarily that it enables a researcher to access deeper parts of an individual’s brain with more precision.
