Simulated tuning curves of disparity-selective cells.

<p>The cell tuning curves in V1 [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0129377#pone.0129377.ref028" target="_blank">28</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0129377#pone.0129377.ref030" target="_blank">30</a>] are simulated by subtracting Gaussians. Each curve corresponds to the response of a single cell and exhibits a similar response pattern as <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0129377#pone.0129377.g009" target="_blank">Fig 9</a> in Gonzalez and Perez [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0129377#pone.0129377.ref030" target="_blank">30</a>]. For example, the red dashed line resembles the TE cell’s response, which gives maximal responses at zero disparity; the blue open-circle line resembles the TN cell’s response, which has similar disparity tuning function as TE cells but peaks at negative disparity; the green star line resembles the FA cell’s response, which activates over a wide range of positive disparities. TF and NE cells are simulated but not marked in the figure. TI cells are not included in the simulation, since their responses could be simulated by assigning negative output weights to the TE cells.
