Scientists are a fractious lot. Near the end of a long discussion (in his study “Retinal ganglion cells responding selectively to direction and speed of image motion in the rabbit,” Horace B. Barlow, R.M. Hill, and W.R. Levick, The Journal of Physiology, vol. 173, no. 3, 1964, pp. 377-407.), Horace Barlow writes:
“Much of this discussion is in close agreement with the ideas of Lettvin and his co-workers but we do not feel happy with the names they give their units.”
Barlow was referring to the ideas reported in the earlier study “What the frog’s eye tells the frog’s brain,” Jerry Y. Lettvin, Humberto R. Maturana, Warren S. McCulloch, and Walter H. Pitts, Proceedings of the IRE 47, no. 11 (1959): 1940-1951.
For a discussion of some recent developments, growths from those ideas, see Mo Costandi’s “Crowdsourcing the retina’s motion detection mechanism” in The Guardian.
