This study covers methodology variability. Three different procedures for calculating the central tendency of tuning curves were evaluated on the same data sets. (Each data set consisted of a collection of points derived from a mathematically defined orientation function for a model cell with, in many cases, an added perturbation. Orientation tuning curves are established quantitatively by use of the first harmonic response to gratings at optimal spatial frequencies and a drift rate of 2 Hz. To do this, gratings are presented monocularly at seven or more orientations in 10° to 15° increments on both sides of the preferred orientation. ing orientation selectivity3, attention4–6,perceptual learning7–9 and auditory processing10.For example, behavioral improvements in the ability of monkeys to discriminate small changes in orientation have been related to sharpening of orientation tuning curves in V1 (ref. 7).

Orientation tuning curve

Some neuronal responses have been hypothesized to be optimally tuned to specific patterns through experience. Neuronal tuning can be strong and sharp, as observed in primary visual cortex (area V1) (but see Carandini 2013-05-23 2016-10-24 2016-09-01 2002-02-05 First, we examine is the effect of the tuning curve width on the tilt illusion.

The results show¨ that the best fitting model function for single-unit orientation tuning curves is a von Mises circular function with a vari-able degree of skewness.

cell’s orientation tuning curve is invariant to changes in stim-ulus contrast (Sclar and Freeman 1982; Skottun et al. 1987): a change in contrast scales all responses by a constant, rather than changing the form of the response tuning curve. 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”]. Downloadable! In frontalized mammals it has been demonstrated that adaptation produces shift of the peak of the orientation tuning curve of neuron following frequent or lengthier presentation of a non-preferred stimulus.
