For the first time, researchers at the University of Minnesota Twin Cities showed that non-invasive brain stimulation can change a specific brain mechanism that is directly related to human behavior.
Mar 15 2024University of Minnesota This is a major step forward for discovering new therapies to treat brain disorders such as schizophrenia, depression, Alzheimer's disease, and Parkinson's disease.
Researchers used what is called "transcranial alternating current stimulation" to modulate brain activity. This technique is also known as neuromodulation. By applying a small electrical current to the brain, the timing of when brain cells are active is shifted. This modulation of neural timing is related to neuroplasticity, which is a change in the connections between brain cells that is needed for human behavior, learning, and cognition.
"The timing of this repeating pattern has a direct impact on brain processes, for example, how we navigate space, learn, and remember," Opitz said. Opitz hopes that this discovery will help bring improved knowledge and technology to clinical applications, which could lead to more personalized therapies for schizophrenia, depression, Alzheimer's disease, and Parkinson's disease.
