Systems and methods for delivering targeted neurostimulation therapies to the nervous system of a subject are provided. A set of electrodes can be strategically distributed around a target nerve, and the nerve can be activated though the electrodes using a channel-hopping interleaved pulse scheduling (CHIPS) stimulation strategy. The systems and methods can leverage the spatiotemporal summation of short, sub-threshold current pulses interleaved across two or more independent stimulation channels (hopping from channel to channel) and delivered across electrodes strategically placed in an interfering configuration around the target neural tissue.

Systems and methods for delivering focalized neurostimulation

Systems and methods for decoding neural and/or electromyographic signals are provided. A system can include at least one single channel decoder. Optionally, the system can include a demixer in operable communication with the single channel decoders. Each single channel decoder can include a filter to attenuate noise and sharpen spikes in the neural and/or electromyographic signals, a detection function to identify spikes, and a demodulator to get a real-time estimate of motor intent.

Systems and methods for decoding intended motor commands from recorded neural signals for the control of external devices or to interact in virtual environments

Systems and methods to simulate activity that would be recorded using an interface to nerve fibers are provided. Signals, such as motor intent signals, can be converted to neural recordings, such as neural recordings by longitudinal intrafascicular electrodes (LIFEs). Spinal cord motor pools and neural interfaces can be jointly simulated. Realistic simulated neural recordings, such as from electrodes such as LIFEs, can be provided and can be used for the evaluation of decoding algorithms. Systems and methods described herein provide a framework for developing neural interface devices.

Neural interface activity simulator

A modular multi-channel inline connector system that connects an implanted electrode within a body of an organism, such as the human body, with a device located external to or implanted within the body. The modular multi-channel inline system comprises of a first lead operatively connected to the implanted electrode and to a first connector portion. A second lead is operatively connected to a second connector portion and operatively connected to the device. One of the first and second connector portions comprises a male connector and the other of the first and second connector portions comprises a female connector. The first and second connector portions are arranged to connect with each other and to be operatively located embedded within the body.

Modular multi-channel inline connector system

Techniques, apparatuses, and systems for interfacing multiple sensors with a biological system can include amplifying signals from respective sensors associated with an external device; modulating the amplified signals based on respective different frequency values; and summing the modulated signals to produce an output signal to stimulate a biological system.

Communication interface for sensory stimulation

A method of determining an optimal coil shape for use in magnetic stimulation includes identifying a stimulation location and a constraint at the stimulation location. A first electromagnetic effect at the stimulation location is determined. The first electromagnetic effect is induced by a first electrical quantity assigned to a first current element at a first current element location with a first orientation. A second electromagnetic effect at the stimulation location is also determined. The second electromagnetic effect is induced by a second electrical quantity assigned to a second current element at the first current element location with a second orientation. Based on the first electromagnetic effect and the second electromagnetic effect, an optimal orientation of a current element at the first current element location is determined. The optimal orientation is such that the constraint is satisfied. Repeating the process at a plurality of locations yields the optimal coil shape.
