More specifically, she has studied the neurological bases of American Sign Language extensively, and her work has led to the discovery that the left hemisphere of the human brain becomes specialized for language, whether spoken or signed, a striking demonstration of neuronal plasticity. Bellugi received a Bachelor of Arts from Antioch College in 1952 and an Editor.D. from Harvard University in 1967.
Broadly stated, she conducts research on the biological bases of language. She has also investigated the language abilities of individuals with Williams Syndrome, a puzzling genetically based disorder that leaves language, facial recognition and social skills remarkably well-preserved in contrast to severe inadequacy in other cognitive aptitudes. The search for the underlying biological basis for this disorder is providing new opportunities for understanding how brain structure and function relate to cognitive capabilities.
Since then, she has held positions as a tenure-track professor at the Salk Institute (1970 forward) and as an adjunct professor at the University of California, San Diego (1977 forward) and San Diego State University (1995 forward).
