WebBiological Sciences 300/301, Smith College Neurophysiology Videos of Units in Visual Cortex: In the 1960s, David Hubel and Torsten Wiesel made the first systematic recordings from primary visual cortex in cats and monkeys. They succeeded in driving individual cortical neurons by projecting light or dark bars onto a screen in front of the anesthetized … WebAbstract. 1. The striate cortex was studied in lightly anaesthetized macaque and spider monkeys by recording extracellularly from single units and stimulating the retinas with spots or patterns of light. Most cells can be categorized as simple, complex, or hypercomplex, with response properties very similar to those previously described in the cat.
