Feb 24 2024Institute for Basic Science The human brain's adaptability to internal and external changes, known as neural plasticity, forms the foundation for understanding cognitive functions like memory and learning, as well as various neurological disorders. New research conducted by a team led by Dr. PARK Joo Min of the Center for Cognition and Sociality within the Institute for Basic Science unveils a novel technique that could transform the treatment landscape for brain disorders.
In the latest study unveiled by the IBS, researchers used ultrasound to enable precise stimulation of specific brain areas. Unlike electromagnetic waves, ultrasound has the advantage of being able to penetrate deep into the brain tissues. The researchers discovered that ultrasound stimulation can modulate neural plasticity - the brain's ability to rewire itself - through the activation of key molecular pathways.
One of the most promising aspects of this new technology is its ability to facilitate the acquisition of new motor skills. When the researchers delivered ultrasound stimulation to the cerebral motor cortex in mice, they observed significant improvements in motor skill learning and the ability to retrieve food. Interestingly, researchers were even able to change the forelimb preference of the mice.
