Horace Basil Barlow FRS (8 December 1921 – 5 July 2020) was a British vision scientist.
[3] In 1953, Barlow discovered that the frog brain has neurons which fire in response to specific visual stimuli.
In 1961, Barlow wrote a seminal article[4] where he asked what the computational aims of the visual system are.
He concluded that one of the main aims of visual processing is the reduction of redundancy, which has been extended to the efficient coding hypothesis.
[citation needed] Barlow was a fellow of Trinity College, University of Cambridge.
