Median % (range) of cells tuned to the specific visual stimulus parameter (single or multiunit recordings) across seven electrophysiological studies published up to 2002. Modified from the summary of Shipp and Zeki (2002a) with permission from Cambridge University Press. The definitions of tuning and stripe type varied between studies. *Disparity or binocular interaction. Data originally from: 1, DeYoe and Van Essen (1985); 2, Peterhans and von der Heydt (1993); 3, Levitt et al. (1994a); 4, Munk et al. (1995); 5, Roe and Ts’o (1995); 6, Gegenfurtner et al. (1996); and 7, Shipp and Zeki (2002a).
