Furthermore, MI modulated risk-taking behavior in the DLB both genotype- and MI size-dependently since 5-HTT+/− mice with small (<30%) infarcts spent considerably more time in the light than their MI > 30% counterparts and compared to the other two 5-Htt genotypes within the MI < 30% group (p < 0.05; Figure 6F; Supplementary Table S7). The gene discussed is HTT; the disease is Lewy body dementia.
