NTRK2 and Stroke: Aged stroke animals treated with IgG-Fc or TrkB-Fc showed no asymmetry between left and right hemispheres following a PFC stroke (IgG-Fc—left: 0.632 ± 0.139 mm3, right: 0.640 ± 0.205 mm3; TrkB-Fc—left: 0.621 ± 0.170 mm3, right: 0.665 ± 0.221 mm3; p = 0.9247, F(1, 30) = 0.0090; Figure 2(b)) and presented with average stroke volumes similar to aged and young stroke animals (IgG-Fc—1.28 ± 0.259 mm3; TrkB-Fc, 1.29 ± 0.186 mm3; p = 0.9739, F(1, 30) = 0.0011).
