Dosimetric analysis of Specific Absorption Rates (SARs) in the rat brain during exposure to 1800 MHz LTE. The heterogeneous model of phantom rat and loop antenna previously described62 was used to evaluate the local SAR in the brain with a 0.5 mm3 cubic mesh. (a) Global view of the rat phantom in the exposure setup with the loop antenna above its head and the metal-free heat pad (yellow) under the body. (b) Distribution of SAR values in the adult brain at 0.5 mm3 spatial resolution. The areas delimited by black contours in sagittal sections correspond to the primary auditory cortex in which microglia and neuronal activity were analyzed. The color-coded scale of SAR values applies to all numerical simulations shown in the figure.
