Abstract

In the retina of the tiger salamander the dynamic properties of rod and cone cells were studied by intracellular recordings. The light stimuli used were circles of either 15 or 1000 μm radius. Photoresponses to 20 msec dim flashes of light could be exactly predicted from the frequency analysis results. Both rod and cone cells show low pass characteristics when stimulated with the small spot. Stimulation with the large spot modifies only the frequency characteristics of cone cells thus suggesting interactions with second order neurons which are absent in rod cells.

Color VEPs in Parkinson's disease
1994, Electroencephalography and Clinical Neurophysiology/ Evoked Potentials
Evoked potential studies have confirmed visual pathway impairment in Parkinson's disease. Dopamine is also known to be involved in retinal color vision mechanisms. In this study, pattern evoked potentials were recorded in 20 parkinsonian patients in “on” and “off” conditions to compare the sensitivity of black-and-white and color pattern stimuli. Evoked responses to colored patterns proved more sensitive to l-DOPA therapy. This finding supports the proposed dopamine modulation of the retinal color system and suggests that color pattern evoked potential studies might be used in monitoring dopamine therapy in parkinsonian patients.
Temporal information processing in cones: Effects of light adaptation on temporal summation and modulation
1985, Vision Research
We have studied the temporal information processing of turtle cones in steady states of light adaptation using intracellular recording techniques. We measured the linear range incremental sensitivity of cones as a function of the stimulus duration. Linear range incremental sensitivity is a function of the background intensity. It is also proportional to the duration of short duration stimuli but is independent of duration for long duration stimuli. The plot of log sensitivity versus log stimulus duration displays two straight line asymptotes; a slope of one for short durations and a slope of zero for long durations. These asymptotes intersect at a time, the critical duration, which decreases with increasing background intensity. Linear systems theory was used to predict these results in addition to the interdependence of critical duration, response kinetics, and sensitivity for any state of adaptation. We have also calculated cone sensitivity as a function of sinusoidal frequency for a variety of background intensities. Correlations between these results and psychophysical studies suggest that the limits on temporal summation established by the cones appear not to be substantially altered by the rest of the retina.
Retinal mechanisms of visual latency
1978, Vision Research
The time-course of light-induced potential changes was measured transretinally as a function of flash intensity in the eyecup preparation of dark-adapted Bufo marinus. The electroretinogram (ERG) as indexed by the peak amplitude of the a-wave. and the latency of the a-wave onset yielded action spectra matching that of the red rod pigment (λ_max at 502 nm) at low intensities near threshold, but at higher intensities there was evidence of intrusion from the single and principal short-latency, longwave cones (λ_max at 575 nm). With uniform illumination of the retina with monochromatic (λ = 502 nm) flashes to isolate the red rod system over a range of 5 log units from threshold to saturation of the a-wave. the latency of the b-wave onset and the latency of the a-wave peak varied linearly with the latency of the a-wave onset. All three measures could be described by linear functions of the inverse cube root of flash intensity, or equivalently by the equation: t_min/t=I^1/3(I^1/3 + σ^1/3). For the mass receptor potential (MRP) isolated with excess Mg²⁺. the initial segment and functional form of the time-course did not differ from that obtained for the a-wave at the same saturating intensity. The results are consistent with the hypothesis that the dominant mechanism controlling visual latency lies in the photoreceptors and that subsequent proximal transformations of the time-course are linear.
