Summary of experimental results in the object-localization task [37].
Abstract
<p><b>(a)</b> Top, schematic illustrates measurement of whisker position (azimuthal angle <i>θ</i>), instances of touch and an example trace of whisker position. Protraction corresponds to positive changes in <i>θ</i>. <b>(b)</b> Schematics of the thalamocortical circuit and relevant cell-types. <b>(c)</b> Spike rate aligned to transitions from non-whisking to whisking (adapted from panel 5e in [<a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1005576#pcbi.1005576.ref037" target="_blank">37</a>]). <b>(d)</b> Average spike rate as a function of whisking amplitude. <b>(e)</b> Average population response aligned to touch (adapted from panel 5c in [<a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1005576#pcbi.1005576.ref037" target="_blank">37</a>]). Data and figures corresponding to previously reported datasets [<a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1005576#pcbi.1005576.ref036" target="_blank">36</a>, <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1005576#pcbi.1005576.ref037" target="_blank">37</a>].</p- Image
