A neurological control system for modulating activity of any component or structure comprising the entirety or portion of the nervous system, or any structure interfaced thereto, generally referred to herein as a “nervous system component.” The neurological control system generates neural modulation signals delivered to a nervous system component through one or more intracranial (IC) stimulating electrodes in accordance with treatment parameters. Such treatment parameters may be derived from a neural response to previously delivered neural modulation signals sensed by one or more sensors, each configured to sense a particular characteristic indicative of a neurological or psychiatric condition.

Apparatus is provided for applying current to a nerve, including a housing that is adapted to be placed in a vicinity of the nerve. First, second, and third electrodes are fixed to the housing at first, second, and third longitudinal sites of the housing, respectively. The first, second, and third electrodes do not come in direct physical contact with the nerve. The second site is between the first and third sites. The second electrode has an electrode surface axial length. The apparatus also includes first and second internal insulating elements, which are fixed to the housing between the first and second longitudinal sites, and between the second and third longitudinal sites, respectively. The first and second internal insulating elements are shaped so as to define, upon placement of the housing, a nerve axial distance between the first and second internal insulating elements that is less than the electrode surface axial length.

At least one electrical brain signal is received from a patient and is demultiplexed into an efferent motor intention signal and at least one afferent sensory signal (such as an afferent touch sense signal and/or an afferent proprioception signal). A functional electrical stimulation (FES) device is controlled to apply FES to control a paralyzed portion of the patient that is paralyzed due to a spinal cord injury of the patient. The controlling of the FES device is based on at least the efferent motor intention signal. A demultiplexed afferent touch sense signal may be used to control a haptic device. The afferent sensory signal(s) may be used to adjust the FES control.

The invention discloses a system and a method for animal robot autonomous navigation. The system comprises a GPS module arranged on a controlled animal, a multi-channel neural signal stimulation module and a control module. The GPS module is configured to receive a GPS satellite signal, and outputs current position information of an animal robot to the control module. The control module is configured to receive the current position information of the GPS module, and compare the current position information with set target position information, to determine a navigation path and form a control instruction. The multi-channel neural signal stimulation module is configured to include a mirror current source, a boost circuit, and an analog multiway switch. Through the connected mirror current source and the boost circuit, constant current is obtained. According to the control instruction, a corresponding channel of the analog multiway switch is selected to output constant current which acts on a neural control region of the controlled animal, to realize output of simulation neural coding information and realize navigation.

The invention discloses an artificial neural control method for upper limb motions of a humanoid robot. The method comprises a first part of establishing a model and templates, and a second part of selecting the templates and controlling output. The first part comprises establishment of the upper limb dynamic model and the initial motion templates of the humanoid robot. The second part comprises the steps that (1) a new motion task position is given; (2) the motion templates are selected in a distinguished manner according to the quantity of execution times of the step; (3) based on a weight and a control signal of each motion template, a control signal needed by the new motion task is calculated, and a destination position of upper and lower limb motions under the signal is calculated; and (4) circulating execution conditions are set, and the steps (2), (3) and (4) are repeated, the final motion template of the new tasks is output, and the motion is executed. The method has the advantages that the calculation quantity is greatly reduced; the responding speed is increased; and learning capability is strengthened.
