LSAMP and Anxiety: Lamprecht et al. (2009) established that fear conditioning caused changes in the Lsamp transcript expression in the amygdala of rats. Altogether, rodent studies indicate that increased level of the Lsamp transcript in several brain areas is related with increased trait anxiety (Nelovkov et al., 2003,2006; Alttoa et al., 2010), acute fear reaction (Kõks et al., 2004), and fear conditioning (Lamprecht et al., 2009).
