Imaging appetite by fDWI in the hypothalamic nuclei of the mouse brain. (A) Axial MRI section containing the hypothalamus in a representative mouse brain and in a brain atlas (inset) showing the localization of the main periventricular hypothalamic nuclei: Dorsomedial Nucleus (DMN, red), Ventromedial Nucleus (VMN, yellow), and Arcuate Nucleus (Arc, blue). (B,D,F,H) Hypothalamic color maps of diffusion parameters from fed or fasted mice, superimposed to T_2w images in different hypothalamic nuclei. The hypothalamic region is depicted enlarged in the corresponding lower panels. (C,E,G,I) D_slow bar graphs of parameter values corresponding to the (B,D,F,H) panels, respectively. ^*p < 0.05, ^***p < 0.001. Reproduced from Lizarbe et al. (2013) with permission of the publisher.
