Brain sites observed with near infrared spectroscopy.

<p>The oxyhemoglobin concentrations in the left and right regions (channels 1 and 2, respectively) over the lower dorsolateral prefrontal to orbitofrontal areas were measured. These regions are labelled in the standard brain space <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0059324#pone.0059324-Tsuzuki1" target="_blank">[38]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0059324#pone.0059324-TzourioMazoyer1" target="_blank">[39]</a>.
