In 1983, I became the Vincent and Brook Astor Professor at The Rockefeller University, where I established a new Laboratory of Neurobiology and continued my close collaboration with Charles Gilbert on the circuitry of primary visual cortex.

Innate mechanisms endow the visual system with highly specific connections, but visual experience early in life is necessary for their maintenance and full development. Deprivation experiments demonstrate that neural connections can be modulated by environmental influences during a critical period of postnatal development.

By the late 1970s, repression and economic chaos were causing increasing unrest throughout Latin America. Army strongmen were forced to cede power in Peru, Argentina, Uruguay, Brazil, Ecuador, Bolivia, Nicaragua, El Salvador, Honduras and the Dominican Republic.
