neurostimulation Timing May Improve brain Injury Recovery
Updated June 13, 2025
New research indicates that the specific timing of neurostimulation could aid recovery from mild traumatic brain injury (mTBI).Scientists at Virginia Tech’s Fralin Biomedical Research Institute at VTC,publishing in the Journal of Neurotrauma,found that precisely timed impulses can rebalance synaptic connections between nerve cells,selectively strengthening or weakening them.
The study suggests that irregular patterns of impulses may be more effective for treating brain disorders, including concussions. According to the Centers for Disease Control and Prevention, over 2.1 million head traumas are treated in U.S. emergency rooms annually,with many more going unaddressed.
Michael friedlander, executive director of the Fralin Biomedical Research Institute at VTC and a co-corresponding author, said the findings suggest that “we might potentially be able to use different patterns of brain stimulation to help treat mild traumatic brain injuries.”
By adjusting things like the timing, frequency, and consistency of the stimulation, we might be able to strengthen specific connections in the brain, which could help improve brain function after injury,” Friedlander said.
Brain stimulation is increasingly used to treat neurological and psychiatric disorders, such as depression and Parkinson’s disease. However, the timing patterns of stimulation have received little attention.
The researchers discovered that irregular stimulation patterns at certain frequencies affect injured brains differently than normal brains. These patterns strengthened connections in injured brains while weakening them in normal brains.
Quentin Fischer, research assistant professor at the Fralin Biomedical Research Institute and co-corresponding author, likened the difference to “the difference between a very organized concerto piece, and jazz, where the musicians are playing around with the patterns.”
We found that highly irregular patterns of stimulation in the normal brain led to a decrease in the strength of connections between neurons, but in the injured brain, that same irregular pattern of stimulation, at the same frequency and continuity, resulted in a strengthening of those connections,” Fischer said.
Friedlander emphasized the importance of understanding how synapses respond to different stimulation patterns in normal versus injured brains. He noted that even mild traumatic brain injuries can have lasting effects on cognitive function and mood.
What’s next
The researchers plan to further investigate the optimal timing and patterns of neurostimulation to refine therapies for mTBI and other brain conditions,potentially leading to more effective treatment strategies.
