A system for affecting an emotional response of a subject to an audio or visual presentation by neurostimulation concurrent with the audio or visual presentation, comprising: a memory; at least one automated processor configured to define a neurostimulation pattern; and a stimulator configured to expose the subject to a stimulus dependent on the neurostimulation pattern, wherein the stimulator is configured to expose the subject to the stimulus comprising at least one of an auditory stimulus and a visual stimulus, the stimulus being modulated according to at least the frequency pattern of the profile, in a manner adapted to entrain the brainwaves of the subject with the recorded brainwave pattern and induce a target emotional state in the subject, CHARACTERIZED IN THAT the memory is configured to store a plurality of profiles associated with different target emotional states, each profile comprising a frequency pattern derived from a recorded brainwave pattern of at least one donor engaged in the respective different target emotional state, the respective different target emotional states being associated with predetermined portions of the audio or visual presentation; the at least one automated processor is configured to define the neurostimulation pattern for stimulation of the subject with the stimulator during presentation of the respective portion of the audio or visual presentation, based on the predetermined portions of the audio or visual presentation and the associated respective profiles; and the stimulator is configured to induce the target emotional state in the subject associated with a concurrently presented portion of the audio or visual presentation. a memory; at least one automated processor configured to define a neurostimulation pattern; and a stimulator configured to expose the subject to a stimulus dependent on the neurostimulation pattern, wherein the stimulator is configured to expose the subject to the stimulus comprising at least one of an auditory stimulus and a visual stimulus, the stimulus being modulated according to at least the frequency pattern of the profile, in a manner adapted to entrain the brainwaves of the subject with the recorded brainwave pattern and induce a target emotional state in the subject, CHARACTERIZED IN THAT the memory is configured to store a plurality of profiles associated with different target emotional states, each profile comprising a frequency pattern derived from a recorded brainwave pattern of at least one donor engaged in the respective different target emotional state, the respective different target emotional states being associated with predetermined portions of the audio or visual presentation; the at least one automated processor is configured to define the neurostimulation pattern for stimulation of the subject with the stimulator during presentation of the respective portion of the audio or visual presentation, based on the predetermined portions of the audio or visual presentation and the associated respective profiles; and the stimulator is configured to induce the target emotional state in the subject associated with a concurrently presented portion of the audio or visual presentation.
