How unusual early visual experiences can change the brain areas that recognize objects
Effects of Abnormal Early Experience on IT Circuitry
This project looks at how atypical visual experiences in early life change the brain circuits that help people recognize faces, text, bodies, and places.

What this research studies
If you take part, researchers would compare people who had typical early vision with those who had early visual problems and also study animals where early vision is experimentally altered, using brain imaging, recordings, and vision tests. They focus on the inferotemporal cortex, a part of the brain important for recognizing objects, to see how neurons respond differently after abnormal early experience. Some work is done in monkeys with controlled changes in what young animals see, and other parts use human imaging or behavioral testing to connect animal findings to people. The overall aim is to link specific early visual experiences to lasting changes in brain wiring that affect object recognition.
Who could benefit from this research
Good fit: People who had documented abnormal visual experience in early childhood (for example early childhood cataract, strabismus, or amblyopia) or adults willing to undergo vision testing and brain imaging would be the most relevant candidates.
Not a fit: People whose vision loss started in adulthood or whose primary problems are progressive retinal or optic nerve diseases may not benefit directly from this work.
Why it matters
Potential benefit: Could improve understanding of how early visual problems lead to lasting vision and recognition difficulties and guide better timing or types of therapies for developmental visual disorders.
How similar studies have performed: Previous work in monkeys and humans shows that visual experience shapes cortical object domains, so this project builds on established findings while using specific early-life manipulations that are less tested.
