Summary

Around the 1950s, a wealth of behavioral experiments had characterized many phenomenological aspects of visual perception that begged for a mechanistic explanation (Chapter 3). Lesion studies had provided a compelling case that damage to circumscribed brain regions led to specific visual processing deficits (Chapter 4). These lesion studies pointed to specific brain areas to investigate visual processing, especially the primary visual cortex in the back of the brain. In addition, the successful use of microelectrode electrical recordings had led to direct insights about the function of neurons within the retinal circuitry (Chapter 2). The time was ripe to open the black box of the brain and begin to think about how vision emerges from the spiking activity of neurons in the cortex.
