Interocular transfer of tuning shift in cat V1. (a) Orientation tuning of a cell measured through the contralateral eye during control (circles), after 9 min of S+15° → So conditioning through the ipsilateral eye (triangles), and after 9 min of S-15° → So ipsilateral conditioning (rectangles). Solid, dashed, and dotted curves represent Gaussian fits of the data. Vertical dashed lines indicate peak positions of the fits; horizontal arrows indicate directions of shifts. (b) Tuning of another cell measured through the contralateral eye during control, after 9 min of So → S+15° ipsilateral conditioning, and 9 min of So → S-15° conditioning. (c) Conditioning-induced shifts (means ± SE) in orientation tuning in a population of cells measured through the conditioned (open bars, n = 116 and 148 for So → S±15° and S±15° → So, respectively) and nonconditioned (filled bars, n = 28 and 72) eyes.
