1. The distributed human neural system for face perception
-James V. Haxby, Elizabeth A. Hoffman, M. Ida Gobbini

2. Face Perception Consists of two parts:
Highly developed visual skill in humans
Mediated by a Neural system
Consists of two parts:

3. Neural System
Core System
Extended System
Prefrontal Region

4. Core-3 bilateral regions
Inferior Occipital Gyrus
-input to both regions
Superior Temporal Sulcus
-changeable aspects
Fusiform Gyrus
-representation of Identity

5. Extended-additional regions
-Interpret meaning from faces
Amygdala (limbic) and Prefrontal cortex
( Inferior Frontal Gyrus, Orbitofrontal Cortex )
*Temporal- auditory
*Parietal-spatial attention

6. How did they know?

7. Face-responsive Regions
Core System
Lateral Fusiform Gyrus
Activity Response
“Fusiform Face Area”

8. Core Neural system
Step 1 Face Identification

9. Extended Neural System
Step 2
Perceive face and expression
Step 3
Infer mood
“He is Upset”

10. Direct vs. Averted Gaze
Which is more interesting?

11. Face Perception and Spatial Attention
Superior Temporal Sulcus +
Intraparietal Sulcus
Parietal Neural Systems
Averted Gaze

12. Face Perception and Spatial Attention

13. Famous Faces Events Anterior middle temporal gyrus
Activation of the appearance
Activation of Semantics
Retrieval of Persons name
….I’ve seen him somewhere….??
Isn’t he the President of the United States….
That’s Barack Obama!!!
