Methods and apparatuses for improving sleep by transdermal electrical stimulation (TES). In general, described herein are methods for applying TES to a subject, and particularly the subject's head (e.g., temple/forehead region) and/or neck with an TES waveform adapted to improve sleep, including reducing sleep onset (falling to sleep) more quickly and/or lengthening the duration of sleep. TES waveform(s) particularly well suited to enhancing sleep are also described herein.

An applicator can include a dispenser for dispensing an amount of a therapeutic composition, which can include an amount of sugar or sugar alcohol and an amount of an alkalizing agent. In some cases, the alkalizing agent can include L-Arginine. In some cases, 75% or more of the composition by weight has a comedogenicity rating of 3 or less on a scale of 0-5. The dispenser can also have a power supply configured to provide power through a contact tip of the dispenser to provide nerve stimulation, such as using vibration, heating, cooling, and/or electrical stimulation.

A hearing training device, is provided, including: a wearable device configured for being worn on the head of a user; a playing device arranged on the wearable device; an acupoint stimulation device, served as a physiotherapy device, comprising a plurality of acupoint stimulation mediums arranged on the wearable device, respectively configured for stimulating a plurality of acupoints on the head of the user and related to hearing, and arranged at the positions of the wearable device corresponding to the acupoints respectively; and a control device being in signal connection with the playing device and storing at least one music file, wherein the control device controls the playing device to play the music file, a beat is formed in an audio track of the music file, and the beat decreases with time, and is fixed until the beat is between 10 Hz and 15 Hz.

A training device for improving insomnia is provided, comprising a virtual reality unit and a control unit. The virtual reality unit comprises two earphones and an eye cover connected to the earphones. When the control unit executes the daytime relaxaion-assisted program, the control unit controls the earphones to play a daytime binaural beats with frequency following response. The daytime binaural beats with frequency following response have a first main carrier frequency tone and a first loading frequency tone differing from the first main carrier frequency tone by a first difference frequency rate. When the control unit executes the nighttime anti-insomnia-assisted program, the control unit controls the earphones to play the nighttime difference frequency tone. The nighttime difference frequency tone have a second main carrier frequency tone and a second loading frequency tone differing from the second main carrier frequency tone by a second difference frequency rate.

A method of transplanting a desired emotional state from a donor to a recipient, comprising determining an emotional state of the donor, recording neural correlates of the emotional state of the donor who is in the desired emotional state; analyzing neural correlates of the emotional state of the donor to decode at least one of a temporal and a spatial pattern corresponding to the desirable emotional state; converting said at least one of a temporal and a spatial pattern corresponding to the desirable emotional state into a neurostimulation pattern; storing the neurostimulation pattern in the nonvolatile memory; retrieving the neurostimulation pattern from the nonvolatile memory; stimulating the recipient's brain with at least one stimulus modulated with the neurostimulation pattern to induce the desired emotional state in the recipient.

Provided are systems, methods, and devices for providing mediation of a traumatic brain injury. Systems may include an interface, processing devices, and a controller. The interface is configured to obtain measurements from a brain of a user with a traumatic brain injury. A first processing device is configured to generate multiple brain state parameters characterizing one or more features of a brain state of the user. A second processing device is configured to generate models of the brain of the user based on the plurality of brain state parameters and the plurality of measurements, and determine, using the models and training data comprising one or more mediation data points, a mediation procedure for reducing one or more symptoms of the traumatic brain injury. The mediation procedure is provided to one or more entities, and one or more control signals are generated by the controller based on the mediation procedure.

Numerous aspects of communication devices, methods, and systems are described in this application. One aspect is an apparatus comprising an energy generator comprising: a plurality of generator elements operable to output a plurality of different energy types in a signal direction toward a physiologic tissue; a printed circuit board that mechanically supports and electrically connects the plurality of generator elements to each other; each generator element of the plurality of generator elements being independently operable, when the energy generator is positioned relative to the physiologic tissue, to communicate with different nerves associated with the physiologic tissue by outputting a different portion of an energy signal in the signal direction toward the physiologic tissue with one energy type of the plurality of different energy types.

Embodiments herein relate to ear-wearable systems and devices that can detect and/or take actions to prevent or alleviate stress related conditions such as post-traumatic stress disorder (PTSD) and the like. In an embodiment, an ear-wearable stress therapy system is included having a control circuit, a first sensor package, a microphone, and an electroacoustic transducer, wherein the electroacoustic transducer is in electrical communication with the control circuit. The ear-wearable stress therapy system can be configured to initiate administration of desensitization and reprocessing (DR) therapy to a device wearer. Other embodiments are also included herein.

The present disclosure pertains to a system and method for providing mandibular advancement and sleep positional therapy to a user for a sleep session. The system is formed by a mandibular advancement device for treating obstructive sleep disordered breathing (e.g., obstructive sleep apnea and snoring) that includes an electronics module configured to aid in sleep positional training. The present system and method facilitate advancing a lower jaw of the user into a protruding position relative to an upper jaw of the user to increase a size of an airway of the user, determining whether a posture of the user has breached a posture threshold, and, responsive to a breach, prompting the user to change posture such that the posture of the user no longer breaches the posture threshold.

A device that suppresses a pathological synchronous and oscillatory neuron activity, and includes a non-invasive stimulation for stimulation, using stimuli, of neurons in the patient's brain and/or spinal cord, where those neurons are showing pathologically synchronous and oscillatory neuron activity, and the stimuli are designed to suppress are this activity when administered to the patient. Moreover, a measuring unit records measurement signals reflecting the neuron activity of the stimulated neurons and a control and analysis unit controls the stimulation unit to administer stimuli, check the success of stimulation based on the measurement, and, if the stimulation success is not sufficient, insert one or more stimulation breaks in the application of the stimuli or extend one or more stimulation breaks, where no stimuli that could suppress the pathological synchronous and oscillatory neuron activity are applied during the stimulation breaks.
