Neural responses were tested for statistical significance during sensory and motor periods in comparison to the baseline period.

<p>The time periods in relation to the events of the task are illustrated in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0085017#pone-0085017-g002" target="_blank">Figure 2</a>. Neurons were included for subsequent analyses on the basis of these screening tests.
