Abstract

A system obtains neuro-response data such as central nervous system, autonomic nervous system, and effector system measurements from subjects exposed to stimulus material. Stimulus material is categorized and/or tagged. Survey based responses and resulting linguistic, perceptual, expressive, and/or motor responses are obtained, integrated with neuro-response data, and stored in a brain pattern analyzer repository. Neurological signatures for concepts such as yes, no, buy, purchase, acquire, like, dislike, correct, incorrect can be determined on a group, subgroup, or individual basis and stored in the brain pattern analyzer repository. The brain pattern analyzer repository may be used to predict behavior based on neurological signatures and/or similarly categorized and tagged stimulus materials that elicit corresponding neuro-response patterns for particular subject groups.

Claims

1. A method, comprising:

determining characteristics of stimulus material for presentation to a subject;

obtaining neuro-response data from the subject exposed to the stimulus material;

predicting expressive response of the subject exposed to the stimulus material by referencing a brain-pattern analyzer repository using the neuro-response data, wherein the brain-pattern analyzer repository includes integrated expressive response and neuro-response data collected from a plurality of subjects exposed to material having characteristics corresponding to the stimulus material presented to the subject.

2. The method of claim 1, wherein expressive response comprises perception.

3. The method of claim 1, wherein expressive response comprises cognition.

4. The method of claim 1, wherein expressive response comprises motor intent.

5. The method of claim 1, wherein neuro-response data is collected using a plurality of modalities including Electronencephalography (EEG) and Electrooculography (EOG).

6. The method of claim 1, wherein obtaining neuro-response data comprises obtaining target and distracter event related potential (ERP) measurements to determine differential measurements of ERP time domain components at multiple regions of the brain (DERP).

7. The method of claim 1, wherein obtaining neuro-response data further comprises obtaining event related time-frequency analysis of the differential response to assess the attention, emotion and memory retention (DERPSPs) across multiple frequency bands.

8. The method of claim 1, wherein the brain-pattern analyzer repository includes integrated survey response, expressive expression, and neuro-response data for a plurality of subjects exposed to materials having a wide range of characteristics.

9. The method of claim 1, wherein expressive response comprises linguistic, perceptual, and motor response.

10. The method of claim 1, wherein predicting expressive response comprises determining a neurological signature for the subject exposed to the stimulus material.

11. An apparatus, comprising:

a stimulus presentation device configured to determine characteristics of stimulus material for presentation to a subject;

a data collection device configured to obtaining neuro-response data from the subject exposed to the stimulus material;

a data analyzer configured to predict expressive response of the subject exposed to the stimulus material by referencing a brain-pattern analyzer repository using the neuro-response data, wherein the brain-pattern analyzer repository includes integrated expressive response and neuro-response data collected from a plurality of subjects exposed to material having characteristics corresponding to the stimulus material presented to the subject.

12. The apparatus of claim 11, wherein expressive response comprises perception.

13. The apparatus of claim 11, wherein expressive response comprises cognition.

14. The apparatus of claim 11, wherein expressive response comprises motor intent.

15. The apparatus of claim 11, wherein neuro-response data is collected using a plurality of modalities including Electronencephalography (EEG) and Electrooculography (EOG).

16. The apparatus of claim 11, wherein obtaining neuro-response data comprises obtaining target and distracter event related potential (ERP) measurements to determine differential measurements of ERP time domain components at multiple regions of the brain (DERP).

17. The apparatus of claim 11, wherein obtaining neuro-response data further comprises obtaining event related time-frequency analysis of the differential response to assess the attention, emotion and memory retention (DERPSPs) across multiple frequency bands.

18. The apparatus of claim 11, wherein the brain-pattern analyzer repository includes integrated survey response, expressive expression, and neuro-response data for a plurality of subjects exposed to materials having a wide range of characteristics.

19. The apparatus of claim 11, wherein expressive response comprises linguistic, perceptual, and motor response.

20. A system, comprising:

means for determining characteristics of stimulus material for presentation to a subject;

means for obtaining neuro-response data from the subject exposed to the stimulus material;

means for predicting expressive response of the subject exposed to the stimulus material by referencing a brain-pattern analyzer repository using the neuro-response data, wherein the brain-pattern analyzer repository includes integrated expressive response and neuro-response data collected from a plurality of subjects exposed to material having characteristics corresponding to the stimulus material presented to the subject.
