Abstract

Example methods, apparatus, systems and machine readable media are disclosed herein for analyzing magnetoencephalographic response data from subjects exposed to media. An example method includes identifying a degree of phase synchrony between a first pattern of oscillation in a first frequency band and a second pattern of oscillation in a second frequency band of magnetoencephalographic response data gathered from a subject exposed to an advertisement or entertainment. In the example method, the magnetoencephalographic response data comprises the first frequency band and the second frequency band. In addition, the example method includes determining an effectiveness of the advertisement or entertainment based on the degree of phase synchrony

Claims

1. A method comprising:

identifying a degree of phase synchrony between a first pattern of oscillation in a first frequency band and a second pattern of oscillation in a second frequency band of magnetoencephalographic response data gathered from a subject exposed to an advertisement or entertainment, the magnetoencephalographic response data comprising the first frequency band and the second frequency band; and

determining an effectiveness of the advertisement or entertainment based on the degree of phase synchrony.

2. The method of claim 1, wherein identifying the degree of phase synchrony comprises detecting a repeating sequence of relative phase angles between the first pattern of oscillation in the first frequency band and the second pattern of oscillation in the second frequency band.

3. The method of claim 1, wherein the first frequency band is generated in a first region of a brain of the subject and the second frequency band is generated in a second region of the brain.

determining a second change between a third amplitude in the second frequency band and a fourth amplitude in the second frequency band; and

determining the degree of phase synchrony based on the first change and the second change.

5. The method of claim 4, wherein determining the effectiveness of the advertisement or entertainment is based on a coherence between the first change and the second change.

6. The method of claim 4, wherein the first amplitude and the third amplitude occur at a first time and the second amplitude and the fourth amplitude occur at a second time different than the first time.

7. The method of claim 1, wherein the first frequency band comprises kappa band waves.

8. The method of claim 1, further comprising determining dipole localization measurements based on the magnetoencephalography data.
