Surround suppression

From neurov.is/on

In ^[1], Hubel and Wiesel discovered that some cells responded less to oriented bars if the bars were extended past their classical receptive fields (CRF). They named these cells "hypercomplex," although the phenomenon is now known as surround suppression ^[2].
