A method of transplanting a sleep state of a first subject (donor) to a second subject (recipient) comprising: capturing a sleep state of the first subject represented by brain activity patterns; and transplanting the sleep state of the first subject in the second subject by inducing the brain activity patterns in the second subject.

In exemplary implementations of this invention, stimuli are intermittently presented to the left or right side of a user. For example, this invention may comprise a method of presenting stimuli to a bilateral organism, which organism has a left side and a right side, wherein: (a) the stimuli are produced by at least one transducer, (b) the stimuli include an intermittent beat train, and (c) the beat train has a beat frequency that is substantially equal to 7.8×(1.618).sup.n Hz, where n is an even integer, which even integer may be negative, zero or positive.

A non-invasive electrical stimulator shapes an elongated electric field of effect that can be oriented parallel to a long nerve, such as a vagus nerve in a patient's neck, producing a desired physiological response in the patient. The stimulator comprises a source of electrical power, at least one electrode and a continuous electrically conducting medium in contact with the electrodes. The conducting medium is also in contact with an interface element that may conform to the contour of a target body surface of the patient when the interface element is applied to that surface. When the interface element is made of insulating (dielectric) material, and disclosed stimulation waveforms are used, the power source need not supply high voltage, in order to capacitively stimulate the target nerve. The stimulator produces a peak pulse that is sufficient to produce a physiologically effective electric field in the vicinity of a target nerve.

Apparatuses (including devices, kits, and systems) and methods to non-invasively and chemically (rather than thermally) activate thermoreceptors to modulate sleep. For example, described herein are apparatuses including topical compositions that stimulate thermoreceptors on the subject's skin (e.g., forehead, hands, and/or feet) for a period of time to induce a sensation of temperature (heat or cold) without significantly altering the person's actual skin temperature to improve sleep quality, including reducing sleep-onset latency, enhancing depth of sleep, and/or extending the amount of time a subject sleeps. The subject may be suffering from insomnia or some other sleep disorder.

An emotional enhancement system for music and film that uses audio and video input to select or generate a stimulation pattern which stimulates the user's face using lights and electrical stimulation directed to certain points on the user's face and head which are believed to induce certain emotions. Using the system, a user's emotional experience of the music or film can be enhanced by inducing emotions in the user coordinated with portions of the music or film. In some embodiments, biometric sensors or cameras and facial tracking software may be used to monitor the emotions displayed by a user while listening to music or watching films, and adjust the stimulation accordingly.

A method and apparatus is disclosed for slow wave sleep improvement. The method includes recording a biosignal from a skin area of a patient using an electrode system. The slow wave stage of NREM sleep is detected by analyzing an oscillation rate of the biosignal. If the slow wave stage is detected, threshold electrocutaneous stimulation is applied to improve the quality of sleep. The described embodiment relates to an apparatus for slow wave sleep improvement comprising an electrode system, a measuring unit, a therapy unit and a processor. The processor is coupled to the measurement unit for receiving the biosignal corresponding to the electrodermal activity. The processor proceses the biosignal to determine the slow wave sleep stage and activates the therapy unit to deliver threshold electrocuteneous therapy to the patient with the purpose of improving the slow wave sleep stage.
