Publication number: 20210282696Abstract: A reinforcement learning brain-machine interface (RL-BMI) can have a policy that governs how detected signals, emanating from a motor cortex of a subject's brain, are translated into action. The policy can be improved by detecting a motor signal having a characteristic and emanating from the motor cortex. The system can provide, to a device and based on (i) the motor signal and (ii) an instruction policy, a command signal resulting in a first action by a device. Additionally, an evaluation signal, emanating from the motor cortex in response to the first action, can also be detected. With the foregoing information, the system can adjust the policy based on the evaluation signal such that a subsequent motor signal, from the subject's brain, having the characteristic results in a second action, by the device, different from the first action, as needed.Type: ApplicationFiled: November 16, 2020Publication date: September 16, 2021Inventors: Joseph T. FRANCIS, Venkata S. Aditya TARIGOPPULA, Brandi T. MARSH

Patent number: 10384064Abstract: Sensory information can be delivered to a subject mammal, for example, for restoring a sense of cutaneous touch and limb motion to the subject mammal. A biomimetic electrical signal is generated based on (a) a stimulation reference signal applied to a somatosensory region of a nervous system of a reference mammal, (b) a stimulated-response signal acquired from a sensory cortex of the reference mammal in response to application of the stimulation reference signal to the thalamic nucleus, and (c) a natural-response signal acquired from the sensory cortex in response to peripheral touch stimuli and/or peripheral nerve stimulation of the reference mammal. The biomimetic electrical signal is applied to a somatosensory region of a nervous system of the subject mammal to induce an activation response, in a sensory cortex of the subject mammal.Type: GrantFiled: May 21, 2018Date of Patent: August 20, 2019Assignee: The Research Foundation for the State University of New YorkInventors: John S. Choi, Joseph T. Francis
