claimStudies on functional changes in the striatum during meditation report conflicting results: Lou et al. (1999, 2005) report decreased activity in the caudate, while Lazar et al. (2000), Tang et al. (2009), and Baerentsen et al. (2010) report increases in the caudate-putamen, and Kjaer et al. (2002) report increases in the ventral striatum.
