Responses of a Weakly Direction-Selective STMD Neuron That Responds to the Visual Clutter Stimulus

<div><p>(A) Length tuning to discrete bar stimuli (see<a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.0040054#pbio-0040054-g002" target="_blank">Figure 2</a>) is typical of STMD neurons, with clear tuning to small features.</p> <p>(B) Raw responses to a target drifted in alternating directions show a vigorous, sustained response as the target crosses the receptive field.</p> <p>(C) The clutter stimulus (<a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.0040054#pbio-0040054-g003" target="_blank">Figure 3</a>A) produces an erratic and weaker response.</p>
