Whilst our findings are consistent with a glial localization of SRR, the greater white than grey matter staining in DPFC (and hippocampus) is at odds with Wolosker et al. (1999a), who suggest that SRR is enriched in grey matter astrocytes, as is d-serine (Nagata et al., 1994; Schell et al., 1995, 1997).
