Comparison between ABA neuronal tracer and diffusion tractography projection. (A) The ABA neuronal projections (colored in red) from the injection site were registered to ABA mouse brain template. ABA brain template (along with the neuronal projections) was registered to our native MR mouse image, where probabilistic fiber data (colored in green) were compared with ABA neuronal tracer projections. (B) Probabilistic tractography (green) and ABA neuronal projections of STN-GPi in control and 6-OHDA mouse model.
