Above the hippocampal CA1 region: the corpus callosum runs from LtoR along the bottom. Concentrated positivity is seen in hypothalamus but, as seen here there is scattered small fibre punctate-positivity in many other areas.
CA3 region of hippocampus. A punctate cytoplasmic positivity is seen in neurones. This extends into what looks to me to be axon hillocks. Rbcs are also positive.
