1. A system, comprising: a data collector to obtain electroencephalography data from a brain of a subject exposed to an advertisement; a data analyzer comprising a processor configured to: detect neuro-response data from the electroencephalography data, the neuro-response data representative of an interaction between a first frequency band of the electroencephalography data and a second frequency band of the electroencephalography data, the second frequency band being different than the first frequency band and occurring at a same time, the interaction between the first frequency band and the second frequency band being represented by a degree of phase synchrony corresponding to a repeating sequence of relative phase angles between a first pattern of oscillation in the first frequency band and a second pattern of oscillation in the second frequency band; and identify one or more priming levels for one or more locations in a source material based on an attribute of the source material; a resonance estimator to determine resonance to the advertisement based on the degree of synchrony; and a selector to select a first one of the one or more locations for inclusion of the advertisement based on the resonance and the one or more priming levels.
