1. A system comprising: a headset to gather data including first neuro-response data and second neuro-response data from a user while the user is exposed to stimulus material, the headset including: a band; a first sensor extending from the band to be located on a first position on a head of the user when the user is wearing the headset, the first sensor to gather the first neuro-response data, the first neuro-response data including at least one of electroencephalographic data or magnetoencephalographic data; a second sensor extending from the band to be located on a second position on the head of the user when the user is wearing the headset, the second sensor to gather second neuro-response data, the second neuro-response data including at least one of electroencephalographic data or magnetoencephalographic data, wherein when coupled to the band, the first sensor and the second sensor are rotatably positionable relative to the band, wherein rotation of the first sensor from the first position to a third position on the head of the user rotates the second sensor relative to the band from the second position to a fourth position on the head of the user when the user is wearing the headset; and a processor programmed to: synchronize the first neuro-response data, the second neuro-response data and the stimulus material to generate synchronized data; and determine an effectiveness of a portion of the stimulus material based on the synchronized data.
