Who are the Nobel Prize-winning researchers that discovered feature detectors in the brain?

The researchers Hubel and Wiesel are renowned for their groundbreaking work in the field of neuroscience, specifically in the study of the visual cortex and how the brain processes visual information. They discovered that certain neurons in the primary visual cortex are specialized for responding to specific features of visual stimuli, such as edges, angles, and movement. These specialized neurons are known as feature detectors.

Their research provided significant insights into how the brain interprets complex visual scenes by breaking them down into simpler elements. By conducting experiments on cats, they were able to demonstrate that these neurons respond selectively to particular patterns of light, essentially showing the brain's organized method of processing visual information. Their findings not only contributed to our understanding of vision but also highlighted the broader concept of how the brain is wired to process different types of sensory information.

This important work earned them the Nobel Prize in Physiology or Medicine in 1981, which is why Hubel and Wiesel is the correct answer in this context.
