About one in five cells in thick stripes were spectrally selective, and they were concentrated toward the outer layers (2 and 6).
The description was consistent with an absolute subdivision of function between stripes that subsequent workers, providing exact percentages, have found less realistic.
Sensitivity to these items could also be found in interstripes, but was absent from thin stripes.
Even a cursory examination reveals cer tain features, for example, an association of spectral sensitivity, and insensitivity to orientation, with thin stripes.
Second, note that the inducing bars replaced some of the light in the purplish and greenish surrounding stripes.
Six inducing bars, of the same height and chromaticity as the test, were inser ted on either six purplish or six greenish stripes.
Since chipmunks usually have characteristic stripes, their stripes might be construed as being standard features displayed by normal chipmunks under normal circumstances.
Epicranium with an ill-defined pair of dusky stripes which converge slightly in front.
