cortical connectivity profile and functions (Behrens et al., 2003). OCD‐related enlargement of the overall thalamus may therefore be driven by one or a few subnuclei. Which subnuclei drive this effect is currently unknown, although shape analysis has revealed increased surface area in anterior and pulvinar nuclei in adult OCD patients (Shaw et al., 2015). In future studies, we will employ the recently developed and validated algorithm from Iglesias et al. (2018) to segment the subnuclei of the thalamus and study which nuclei drive the effect.
