Leveraging a meta-analytical approach, we aggregated across previously published maps of the locus coeruleus (Betts et al., 2017; Dahl et al., 2019; Keren et al., 2009; Liu et al., 2019; Tona et al., 2017; Ye et al., 2020) to derive a biologically plausible volume of interest (meta mask) that shows high agreement across investigations. We freely share the locus coeruleus meta mask with the scientific community
