Columbia University neuroscientists have discovered brain-cell circuitry in fruit flies that transforms raw sensory data into color perceptions. This study highlights how the brain constructs color from light wavelengths and has identified specific neurons responsible for hue selectivity, vital for the survival of certain species.

Perceiving something – anything – in your environment means becoming aware of what your senses are detecting. Today, for the first time,neuroscientists identify brain-cell circuitry in fruit flies that converts raw sensory signals into color perceptions that can guide behavior.“Many of us take for granted the rich colors we see every day – the red of a ripe strawberry or the deep brown in a child’s eyes.
Researchers have uncovered circuitry in the brains of fruit flies that makes color perception possible for them.

Hue denotes the perceived colors associated with specific wavelengths, or combinations of wavelengths of light, which themselves are not inherently colorful.
