Spectrally opponent responses in ground squirrel spermophilus beecheyi optic nerve


Vision Research 20(1): 9-14
Spectrally opponent responses in ground squirrel spermophilus beecheyi optic nerve
The spectral response patterns of single optic nerve fibers of the California ground squirrel (S. beecheyi) were determined in urethane-anesthetized and unanesthetized animals. Fibers showing spectrally-opponent responses were in about the same relative proportions in both preparations. Apparently the units showing spectrally-opponent response patterns in the ground squirrel visual system are not found only under abnormal physiological conditions of the animal.
