3D fUS imaging of brain structures responding to visual stimuli. A. General View of the activated areas, left and right visual cortices (V1/V2), Superior Colliculus (SC) and LGN, which were manually superimposed to a Calabrese rat brain model. B. Sagittal cut at Bregma showing the activated SC. C. Sagittal cut at Bregma +3.7 mm showing both LGN and V1/V2. D. Top view of the brain surface showing V1/V2 activation. E. Transversal cut at 3 mm depth showing the activated SC. F. Transversal cut at 5.4 mm depth showing the activated LGN. Scale bars=2 mm. Brain mini-maps made using (Bakker et al., 2015, Kjonigsen et al., 2015, Papp et al., 2014, Sergejeva et al., 2015) brain atlas.
