The electroretinogram was recorded from the isolated retina of the carp while the temperature was varied systematically and while the preparation was under the influence of various pharmacological agents. In addition to the a-wave and the b-wave, the

The relation between the amplitude of visual responses to a checkerboard stimulus and the degree of lateral displacement of the checks was examined across different check sizes with simultaneously recorded electroretinograms (ERGs) and visual-evoked

The advantages of presenting sensory data in terms of stimulus variables are stressed. Spectral sensitivity plots of local electroretinograms and ganglion cell discharges from the dark-adapted rabbit retina illustrate the utility of using this kind o

Ganglion cell activity in response to drifting or alternating stimulus patterns was recorded in an eyecup preparation of the turtle. The stimuli were sinusoidal gratings with various spatial frequencies and spatial phases. Spike histograms of the act

1. Local electroretinograms and spike activity from ganglion cells were recorded from an eye cup preparation of the turtle retina. The responses were elicited with striped and plaid stimulus patterns. 2. The results obtained with the two forms of rec

We simultaneously recorded PERG and VECP responses from the visual periphery generated by an alternating checkerboard (0.3 checks, 89% contrast) under both steady state and transient conditions. Subjects viewed the stimulus through trial lenses of va

A method has been developed for teaching a graduate course that combines quantitative methods and introductory programming. It has produced an outcome that is of considerable utility in the laboratory. Several features that contribute to the success

The alpha component of the electroencephalogram often hinders evoked potential recording—particularly when the stimulus is restricted to the retinal periphery. In the present report stimulus, electronic, and computer techniques are described for co

Simultaneous spectral sensitivity determinations of the human electroretinogram and the visual evoked potential were made over an adaptation range extending from scotopic to photopic. Determinations were made for the amplitude of the B wave and the l
