History of CNN & its impact in the field of Artificial Intelligence

Hubel and Wiesel's research in the 1950s and 1960s showed that cat visual cortices include neurons that react to tiny parts of the visual field separately. The region of visual space within which visual inputs impact the firing of a single neuron is known as its receptive field while the eyes are not moving. Neighboring cells have receptive fields that are comparable and overlap. The size and location of receptive fields vary consistently across the cortex to generate a full map of visual space. The contralateral visual field is represented by the cortex in each hemisphere.
