Owing to the mathematical simplicity of the OI , most studies over the years have employed the OI to assess orientation selectivity. 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 … Orientation tuning curve: a function relating the firing rate of a neuron to the orientation of the stimulus.

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. Tuning curves widths vary widely in vivo [3].

Orientation tuning curve: a function relating the firing rate of a neuron to the orientation of the stimulus. Complex cells: a neuron in the visual cortex that responds best to moving bars with a particular orientation. End-stopped cells: a cortical neuron that responds best to lines of a specific length that are moving in a particular direction. Start studying Tuning Curves.
