  • TL;DR: Scientific question: How does visual experience impact representations and transformations along the ventral stream? How broad is the human brain’s capacity to ‘retool’ in the face of ‘atypical’ experience?
  • Abstract: Scientific question: A key puzzle in cognitive neuroscience concerns the contribution of innate predispositions versus lifetime experience to cortical function. Addressing this puzzle has implications that reach far, from plasticity of the neural hardware [1] to representations in the mind and their developmental trajectory [2], and even to building artificially intelligent systems [3,4]. Yet, this is a notoriously difficult topic to study empirically. We propose to tackle this issue in the context of the high- level ‘visual’ representations through neural, behavioral, and computational studies of individuals who are sighted and congenitally blind. Congenital blindness represents a uniquely tractable and rich model to study how innate substrate and atypical experience interact to shape the functional tuning of the brain. This work aspires to reveal the origins, including the representational and computational basis, of high-level visual representations by addressing the following questions: How does visual experience impact representations and transformations along the ventral stream? How broad is the human brain’s capacity to ‘retool’ in the face of ‘atypical’ experience?
