Which of the following area of the nervous system where Negri bodies are commonly found?

Rabies is distinguished by the presence of cytoplasmic eosinophilic inclusions, the Negri bodies. They are most prominent in pyramidal cells of the hippocampus and Purkinje cells but have been seen in nerve cells throughout the brain and spinal cord. In addition there is widespread perivascular cuffing and meningeal infiltration with lymphocytes and mononuclear cells and small foci of inflammatory necrosis, such as those seen in other viral infections. The inflammatory reaction is most intense in the brainstem. The focal collections of microglia in this disease are referred to as Babes nodules.
