The schematic summary of results in VBM piled upon the visual stream. The schema of results piled upon the visual stream and the retinotectal pathway in the sagittal sections of the rat brain atlas68. The information from the retina projects to the lateral geniculate nucleus of the thalamus (LGN) and the superior coliculus (SC). The retinotectal pathway: the projection from the superior colliculus to the amygdala (AMY) via the posterior lateral nucleus of the thalamus (PL)32 and the cortical-cortical long-range fasciculi in the ventral stream to the limbic areas55 including the amygdala play key roles in fast visual fear response. Our obtained result shows atrophy in the visual cortex (V1 and V2), and in the ventral lateral area in the thalamus (VL). Because of the atrophy in the visual cortex, the contribution of the retinotectal pathway to visual processing might have relatively increased.
