An advanced system that enables patients to better control prosthetic devices.
Background :
Many pathologies lead to loss of the ability to use one or more limbs. Historically, a lost or damaged limb has been replaced with a prosthetic device. In recent years, prosthetic technology has been developed to enable the control of these devices via a neural signal from the patient. These brain-machine interfaces (BMIs) are advancing towards the true functional replacement of limbs. BMI technology uses mathematical algorithms to translate the patient's intentions via their neural activity. To date, most BMI systems are based on supervised learning, where the patient's intention, actual motion, and target are known. This usually requires somewhat confined conditions, such as those found in a laboratory.
Technology Overview :
The subject technology, developed by researchers at SUNY Downstate Health Sciences University, is a BMI system that uses a "reward/expectation" signal derived from the motor cortex in the patient's brain. This allows the system to be updated without manual intervention from the experimenter. The technology incorporates a "policy" that determines how detected signals emanating from the patient's brain are translated into action. The system can provide a command signal resulting in a first action by the prosthetic device. It can also detect an evaluation signal emanating from the patient's brain in response to the first action. The system can adjust the policy based on the evaluation signal. This allows for more timely, precise, and natural control of the prosthetic device.

About the State University of New York
The State University of New York is the largest comprehensive system of higher education in the United States, and more than 95 percent of all New Yorkers live within 30 miles of any one of SUNY’s 64 colleges and universities. Across the system, SUNY has four academic health centers, five hospitals, four medical schools, two dental schools, a law school, the country’s oldest school of maritime, the state's only college of optometry, 12 Educational Opportunity Centers, over 30 ATTAIN digital literacy labs, and manages one US Department of Energy National Laboratory. In total, SUNY serves about 1.7 million students across its portfolio of credit- and non-credit-bearing courses and programs, continuing education, and community outreach programs. SUNY oversees nearly a quarter of academic research in New York. Research expenditures system-wide are nearly $1.5 billion in fiscal year 2025, including significant contributions from students and faculty. There are more than three million SUNY alumni worldwide, and annually one in three New Yorkers who earn a college degree is a SUNY alum.
