Do you see what I see?
Explore the three areas of the brain that are most involved in recognizing the form of a face:
- pStS (Posterior superior temporal sulcus)
- Lateral fusiform gyrus
- IOG (Inferior occipital gyrus)
Your brain responds:
Your brain interprets the world around you. There is always activity in your brain, but when you see certain things, your brain activity changes in predictable ways. Signals fire from one neuron to another, increasing activity in different areas of the brain. Measurements indicate that oxygen-rich blood moves to areas of the brain when they become more active. fMRI (functional magnetic resonance imaging) technology interprets changes in brain activity by measuring blood flow.
Face to face:
Our ancestors evolved in communities. Those that were able to develop relationships in social groups were more likely to survive. The ability to recognize faces helped them navigate the ancient social scene. We may take it for granted, but in a community, it is important to recognize that we are looking at another person’s face.
