Behavioral tests and MRI preliminary analysis suggest that novel treatment with microglial regeneration could restore spatial memory, enhance cued fear memory and reverse some neuropathological deficits induced by chronic high-altitude exposure.
Representative T2-weighted high resolution image overlayed with manually drawn ROIs, T2 map, T1 map, FA, TR and the template MR image.
The T2, T1, FA, and TR ROIs values in four brain regions are shown on the panel. The analysis of the derived results showing elevated trace values in all selected regions in HA conditioned mice which was reversed by PLX treatment.
