DESCRIPTION:The human brain stores an extraordinary amount of knowledge ab
 out the world\, supporting object recognition\, language\, reasoning\, and
  abstract thought. What is the neural nature of this knowledge? Is semanti
 c knowledge—such as “roses are red”—simply a trace of sensory expe
 rience\, encoded in perceptual brain systems? How does the brain represent
  knowledge acquired through language alone\, without direct perceptual gro
 unding? I will present a series of studies from my laboratory that address
  these questions by examining semantic representations under radically dif
 ferent sensory and linguistic conditions. Using knowledge domains such as 
 object color\, we study congenitally blind individuals\, color-blind indiv
 iduals\, typically developed macaques\, and individuals who experienced ea
 rly language deprivation. Across these populations\, we ask what aspects o
 f semantic knowledge depend on perception\, what can arise independently o
 f it\, and how language reshapes neural representations. Together\, the fi
 ndings suggest that semantic knowledge in the human brain is supported by 
 two distinct yet interacting coding systems\, revealing how perceptual exp
 erience and language jointly contribute to the architecture of human knowl
 edge.\nSpeakers:\nProfessor Yanchao Bi (Peking University)
