At 2months-old, the total variety of STN neurons (WT: 10,373 [9,3414,414]; n = 7; BACHD: ten,638 [10,5133,877]; n = 7; p = 0.7104; Figure 11C), the volume of the STN (WT: 0.098 [0.090.125] mm3; n = 7; BACHD: 0.085 [0.080.111] mm3; n = 7; p = 0.1649; Figure 11C) and STN neuronal density (106,880 [98,10015,985] neurons/mm3; n = 7; BACHD: 124,844 [115,47945,711] neurons/mm3; n = 7; p = 0.1282; Figure 11C) were not diverse in WT and BACHD mice. With each other, these data demonstrate that amongst the ages of two months and 12 months BACHD mice drop around 1 third of their STN neurons in comparison to WT littermates.Atherton et al. eLife 2016;5:e21616.

Break down of H2O2 by catalase includes a fairly minimal effect on autonomous firing in WT STN neurons when compared with BACHD neurons.

Break down of H2O2 elevated autonomous firing in BACHD STN neurons only. The boxplot confirms that the elevation of firing due to catalase application was higher in BACHD mice.
