Presentation Transcript

  1. Face Recognition in the Brain Arash Afraz

  2. How Does the Brain Represent FACE???

  3. Electrophysiological Studies • Imaging Studies • Behavioral Studies

  4. Electro -physiological Studies:

  5. Face selective neurons in the temporal cortex of monkey were reported in 1972.

  6. TE  Face Identity • STS  Facial Expression

  7. Neural Encoding!?!?

  8. Global Categories: Monkey, Human & Shape. • Fine Categories: Monkey Identity (F1), Monkey Expression (F2), Human Identity (F3) & Human Expression (F4)

  9. I See a face – a happy face!

  10. Latency Coding in Face neurons?

  11. Imaging Studies:

  12. Fusiform Face Area Imaging studies (Nancy Kanwisher).

  13. Face neurons are clustered in ventral visual pathway in few patches (say 5 or 6) • Amount and distribution of face selective patches are similar in humans and monkeys

  14. Optical Imaging investigations convey the same results.

  15. Behavioral Studies:

  16. Face Inversion Effects

  17. Face Inversion Effects

  18. Face Inversion Effects

  19. Face Inversion Effects

  20. Laterality in Perceiving Facial Expression

  21. Prosopagnosia

  22. Adaptation and After-effects in Face Perception!?

  23. Simple Adaptations

  24. What about high level visual stimuli like faces?
