In the present study we provide longitudinal insight into the pathological effects of the T. gondii infection on the mouse brain microstructure. We explore the use of DT-MRI and fiber tracking to investigate the impact of the T. gondii infection on the whole brain connectivity pattern, in the living mouse. MR images illustrate the presence of lesions in key brain structures leading to impaired structural connectivity between important areas of the somatosensory and limbic systems. These modifications might explain the sensorimotor deficits observed in the infected mice.
