In a patient suffering from neural impairment, stimulation is provided to sensory surfaces of the face and/or neck, or more generally to areas of the body that stimulate the trigeminal nerve, while performing an activity intended to stimulate a brain function to be rehabilitated. The simulation may then be continued after the performance of the activity has ceased. It has been found that the patient's performance of the activity is then improved after stimulation has ceased. Moreover, it tends to improve to a greater extent, and/or for a longer time, when the post-activity stimulation is applied, as compared to when postactivity stimulation is not applied.

A motor-deficit-therapeutic method (for treatment of a patient who has hemiparesis) includes: providing, to the patient afflicted with hemiparesis, a neurostimulator configured to stimulate a vagus nerve of the patient using electrical stimulation; and initiating stimulation of the vagus nerve so that at least a portion of the stimulation occurs in temporal proximity to performance by the patient of a motor therapy session which is hemiparesis-therapeutic, thereby improving the patient's hemiparesis, the stimulation being provided by the neurostimulator.

Methods and apparatus for improving cognitive function within a human. The invention utilizes a neurostimulation device, such as a signal generator, to affect tissue elements at a lateral temporal lobe of the human brain. The implanted device delivers treatment therapy to thereby improve cognitive function by the human. A sensor may be used to detect various characteristics of cognition. A microprocessor algorithm may then analyze the output from the sensor to regulate delivery of the stimulation therapy.

In an embodiment, an electrical stimulation system can include one or more of an electrode assembly including one or more electrodes and an electronics subsystem. In some variations, each of the one or more electrodes can include a hydrophilic layer and a conductive layer. In some variations, the electronics subsystem can include one or more of a control module, power module, and a stimulus generator. In some variations, the electrical stimulation can further include one or more of an electrical attachment system, mechanical attachment system, head apparel assembly, flexible housing, and/or any other suitable component. The electrical stimulation system functions to apply electrical stimulation but can additionally or alternatively function to measure/and or record one or more biosignals from a user.

The various embodiments described herein include methods, devices, and systems for enhancement of memory. In one aspect, a method includes: (1) implanting intracranial electrodes in a patient, wherein the electrodes are placed selectively at a specific brain site; (2) determining a threshold for eliciting an after-discharge threshold of the patient, and (3) stimulating the electrodes with current set below the after-discharge threshold while the patient is in a particular phase of sleep so as to enhance memory of the patient.

Example apparatus and methods cause activation of target neural tissue through electrical stimulation of a connected white matter tract to reduce the hyper-excitability of the target neural tissue and thus reduce seizures while preserving memory in humans. Example apparatus and methods apply low frequency (e.g., <10 HZ) electrical stimulation to the forno-dorso-commissure (FDC), detect an electrical signal generated in an area connected to, innervated by, or that can be activated by the FDC in response to the stimulation, and reconfigure the stimulation based on the detected signal and a desired therapeutic effect. The stimulation may be reconfigured to produce an electrical stimulation waveform that will produce the desired therapeutic effect. The desired therapeutic effect may be, for example, reducing hyper-excitability of neural tissue in a target area, reducing hippocampal spikes, reducing seizure odds, or improving recall.

A neuromodulation targeting system includes a GUI that facilitates selection of one or more neuromodulation target regions. The GUI provides an interactive display representing anatomy of a patient with user-selectable portions corresponding to a plurality of predefined anatomical regions associated with distinct localized clinical effects of neuromodulation. The system further includes a targeting selector engine that is responsive to user selection of a first portion of the interactive display by configuring delivery of neuromodulation therapy to a first target region to produce a first localized clinical effect in the patient at a location corresponding to the first portion of the display, upon administration of the neuromodulation therapy to the patient.

A method of treating motor deficits in a stroke patient, comprising assessing a patient's motor deficits, determining therapeutic goals for the patient, based on the patient's motor deficits, selecting therapeutic tasks based on the therapeutic goals, performing each of the selected therapeutic tasks repetitively, observing the performance of the therapeutic tasks, initiating the stimulation of the vagus nerve manually at approximately a predetermined moment during the performance of the therapeutic tasks, stimulating the vagus nerve of the patient during the performance of the selected therapeutic tasks, and improving the patient's motor deficits.

Systems and methods of the present disclosure are directed to systems and methods for treating cognitive dysfunction in a subject in need thereof. The system can include a light source and a speaker. A visual neural stimulation system provides, via the light source, visual stimulation having a first value of a first parameter. An auditory neural stimulation system provides, via the speaker, audio stimulation having a second value of the second parameter. A stimuli orchestration component selects, for a first time interval, one of the visual stimulation or the audio stimulation to vary based on a policy, selects, for the first time interval, the other of the visual stimulation or the audio stimulation to keep constant based on the policy, and provides causes the one of the visual neural stimulation system or the auditory neural stimulation system to vary the one of the visual stimulation or the audio stimulation.

Systems and methods for stimulating the sensory cortex of an individual by obtaining a neuronal stimulation signal adapted to provide a movement cue for the individual and transmitting the neuronal stimulation signal to an electric contact of a neuronal stimulation electrode that is already implanted into the brain of the individual for a purpose different from providing the movement cue. Proprioceptive information is communicated to the individual by obtaining information about the body posture of the individual and applying a neuronal stimulation signal to an afferent axon targeting a sensory neuron in the cortex of the individual. The neuronal stimulation signal is determined based on the obtained body posture information and corresponds to the proprioceptive information. A first neuronal stimulation signal providing the movement cue and a second neuronal stimulation signal providing the proprioceptive information may be applied together to the cortex of the individual.
