Biography

Li Chaoyi, male, Han nationality, is a native of Chongqing, Sichuan Province. He graduated from China Pharmacy University.

From the 1980s to the 1990s, Li carried out systematic research on non-traditional receptive fields of the retina, external knee bodies and visual cortex nerve cells. Through experimentation, he determined that outside of the traditional receptive fields of retinas and external knee body nerve cells, there exists a "disinhibition zone" several times the area of receptive field. Li proved that the activity of the zone plays a decisive role on regional brightness and brightness grads of transfer graphics. Also he determined that around the receptive field of primary visual cortex nerve cell, there exists a large area that can modulate the response of receptive field, named "conformable field". Based on careful study on the time-space structure and tune characteristics of "conformable field," Li put forward a new theoretical model of receptive fields with "triplicate structure" to explain multiple functions of receptive fields. He won a second-class award for natural science from the Chinese Academy of Sciences, a national second-class award for natural science and the He Liang-He Li Science and Progress Award.
