Measuring the orientation tuning width requires either substantial sampling of responses to different angles, or performing a tuning curve fit, which we will turn to later. Owing to the mathematical simplicity of the OI , most studies over the years have employed the OI to assess orientation selectivity.

The tuning curves for orientation of cortical cells maintain, to a first approximation, the same shape at the various levels of mean luminance. The results are discussed, comparing the electrophysiological with psychophysical data. Orientation-tuning curves for each neuron at each temporal frequency were fit by Gaussian functions to determine the orientation tuning half-widths at half-maximum response (Fig. 2A; see methods). At the preferred temporal frequency for each neuron, orientation tuning half-width was, on average, 24.9 ± 1.8° (Fig.

Note, that our orientation tuning curves typically had two peaks, one for each direction over 360 deg (see Fig. 2A–L). 2016-10-24 · The reconstructed two-dimensional tuning curve of this example cell (Fig. 3b; see also Supplementary Fig. 8) formed a hill of activity, with the firing rate peaking at a preferred orientation and Tuning curve sharpening for orientation selectivity: coding efficiency and the impact of correlations Peggy Seriès1,Peter E Latham 1 & Alexandre Pouget 2 Right, Orientation tuning curves at various SFs, color coded according to the arrows shown next to the predicted tuning matrix.

to the optimal orientation is visible in neurons (b)and(e). Mexican-hat tuning curves are present in the neurons (c), (d), and (e). This time evolution of the tuning curve shape is believed to be a result of the dynamic competition between cortical excitation and inhibition (Nelson and Frost 1978; Sillito et al. 1980; Shapley

However, other aspects of simple cell responses show a Intracellular measurement of orientation tuning of the membrane potential of a simple cell in cat Vl in warm and cooled conditions. The shapes of the two tuning curves are similar, although their amplitudes are different. (Note the different right and left vertical scales.) Redrawn from [9”].

The variability in estimation of preferred orientation is dependent upon both biological and methodological sources. This study covers methodology variability. Three different procedures for calculating the central tendency of tuning curves were evaluated on the same data sets.
