Apparatuses (e.g., devices, systems), and methods for transdermal electrical stimulation (TES). Apparatuses described herein can be self-contained, lightweight, and wearable. The apparatuses and methods described herein be configured to apply an ensemble current waveform between the two or more electrodes, wherein the ensemble current waveform comprises a series of component waveforms that are sequentially applied, and wherein each component waveform is different from a component waveform immediately before it and wherein transitions between the component waveforms temporally correlates with transitions in the sensory experience. Also described are neurostimulators for application of transdermal electrical stimulation (TES) and methods of using them for comfortably inducing a cognitive effect. Also described are Methods and apparatuses for amplitude modulation of all or a portion of an ensemble waveform to modify a user's cognitive state by transdermal electrical stimulation (TES).

Apparatuses and methods for neuromodulation

Apparatuses and methods of applying transdermal electrical stimulation (TES) to a subject to enhance a concurrent sensory experience, by applying the TES to the subject's head or head and neck from two or more electrodes that are coupled to a neurostimulator. The apparatuses and methods described herein be configured to apply an ensemble current waveform between the two or more electrodes, wherein the ensemble current waveform comprises a series of component waveforms that are sequentially applied, and wherein each component waveform is different from a component waveform immediately before it and wherein transitions between the component waveforms temporally correlates with transitions in the sensory experience. Also described herein are apparatuses and methods for applying TES to a subject's face or face and neck, wherein one end of the TES applicator (e.g., strip electrode) contacts the subject's cheek and/or mastoid. Finally, user interfaces for controlling TES are also described.

Methods for allowing a user to control a neuromodulator to modify a cognitive state being experienced by the user. The user may select a waveform ensemble from a hand-held user device having an interface, and the user may adjust the perceived intensity of the applied waveform ensemble with the user device while the waveform ensemble is being applied. Also described are methods of managing communication between the hand-held user device (such as a smartphone or the like) and a wearable neurostimulator. Methods of displaying and visually tracking and controlling the applied waveform ensemble are also described herein.
