Gina Arata had a bright future ahead of her, preparing for law school after college, until a car accident in 2001 left her with lasting brain damage. Despite her recovery, Arata struggled with memory impairment, motor issues, and a short temper. However, thanks to a groundbreaking deep-brain stimulator, Arata and several other patients have regained some of their thinking skills. This implant offers new hope for treating long-lasting impairments caused by traumatic brain injuries.
Testing the Power of Brain Implants
More than 5 million Americans live with lasting effects from traumatic brain injuries, which can include difficulty focusing, memory problems, and impaired decision-making ability. Unfortunately, there are limited treatment options available for these patients. However, a recent study conducted by Stanford researchers has revealed exciting findings.
🔍 Researchers hypothesized that electrical stimulation targeted at the central lateral nucleus in the thalamus could potentially reactivate damaged neural pathways associated with cognitive function. To test this theory, Arata and four other patients, who had all suffered brain injuries at least two years prior, were recruited for the study.

Sparking Progress: The Power of Electrical Stimulation
Before the deep-brain stimulator implantation, precise targeting was essential. Each patient’s brain had a unique shape, requiring researchers to create a virtual model to pinpoint the correct location for the implant and determine the level of electrical stimulation needed.
💡Following the implant surgery, the participants went through a 90-day trial period with the device turned on for 12 hours each day. During this period, researchers assessed their progress using a standard test of mental processing speed called the trail-making test. Astonishingly, the participants’ test results showcased an average speed improvement of 32%.
Reclaiming Everyday Life
The benefits of the deep-brain stimulator were not limited to the test results alone. Patients quickly regained lost abilities and resumed activities they thought were impossible, such as reading, watching TV shows, playing video games, and completing homework assignments. Fatigue levels decreased, eliminating the need for napping throughout the day.
👥 However, a captivating twist emerged during the final phase of the trial. Researchers had planned to randomly select half the patients, turn off their devices, and compare their brain performance to those with active devices. Yet, two patients declined the opportunity, fearing a regression in their progress. Only three participants agreed to take part, with one randomly assigned to have the device turned off. After three weeks without stimulation, this participant’s trail-making test results indicated a 34% decrease in speed.
The Path Forward
This trial represents a pioneering moment in deep-brain stimulation for traumatic brain injuries. The promising results from this study bring hope to those struggling to recover their cognitive function to its fullest extent. Study co-researcher Dr. Nicholas Schiff says, “Our goal now is to try to take the systematic steps to make this a therapy. This is enough of a signal for us to make every effort.”
