“…This result is consistent with target sizes used in studies in which rhesus long wavelength sensitivity was suppressed relative to the human (9,10,(16)(17)(18). In other rhesus and human comparisons of photopic spectral sensitivity, much more agreement exists between human and rhesus in the spectral sensitivity range from 580 to 640 nm (6)(7)(8). However, all of these studies utilized test targets many times larger than the test target limits which we used for observing rhesus long wavelength insensitivity.…”

“…However, all of these studies utilized test targets many times larger than the test target limits which we used for observing rhesus long wavelength insensitivity. Yet, in at least two studies (7,8) a small deficit in rhesus long wavelength sensitivity either appeared without comment or was noted and dismissed as incidental experimental variation.…”

“…Microspectrophotometric (MSP) measurements of rhesus cone photopigments, measured indiscreetly from foveal and parafoveal retinal regions, compare favorably with psychophysical measurements of cone fundamentals (5). Measurements of rhesus photopic spectral sensitivity have been demonstrated to fit the human photopic functions with small departure in the short wavelength region generally attributed to differences in lens pigmentation (6)(7)(8). Human achromatic acuity is slightly better at high photopic luminance levels and rhesus acuity is better at scotopic acuity luminance levels (4).…”

“…Several authors, using different techniques, have measured the photopic spectral sensitivity of various species of Cercopithecoidea (Grether, 1939;Sidley, Sperling, Bedarf & Hiss, 1965;Schrier & Blough, 1966;Sidley & Sperling, 1967;Behar & Bock, 1974;De Valois, Morgan, Polson, Mead & Hull, 1974;Zwick & Robbins, 1978). Because different procedures are known to affect the shape of luminosity curves (Borstein & Marks, 1973), it is not unexpected that these studies have reported curves of somewhat different shapes.…”

SUMMARY1. The spectral sensitivity of two varieties of macaque Y ganglion cells with a centre-surround organization, type III (non-colour opponent) and type IV (broadband colour opponent), was examined with test stimuli of different size, shape and wave-length.2. The spectral sensitivity of type III cells to large stimuli decreased at the long wave-lengths with decreasing retinal eccentricity; this change was due to a lower sensitivity of green-sensitive than of red-sensitive cone input to the surround of foveal cells, which resulted in stronger surround antagonism at the long than at the short wave-lengths leading to a rudimentary form of colour opponency.3. The spectral properties of foveal type III cells were intermediate between those of perifoveal type III cells, whose surrounds received a rather similar input from both cone types, and of the predominantly foveal type IV cells, whose surrounds appeared to lack input from green-sensitive cones.4. The results indicate that both cell types represent varieties within a continuum of a single macaque Y-cell system which has a reduced long-wave-length sensitivity in the foveal region. The fact that a similar reduction of long-wave-length sensitivity can be observed in (foveal) macaque photopic luminosity functions measured with different techniques by different authors suggest that both types of Y cell have an important role in the processing of luminance information.

“…Finally, it should be pointed out that the present results are quite similar to those previously reported for this species by Jones, Polson, and DeValois (1964), using ERG measures. is difficult to compare the present results with those of Sidley, Sperling, Bedarf, and Hiss (1965). However, there 'ire discontinuities in the individual photopic functions that suggest secondary peaks corresponding 422 btes…”
