Description: Frontal (transverse) paraffin sections through a telencephalic hemisphere of a European hedgehog stained by the Nissl method. The section shows the overall cytoarchitecture of a hemisphere and all major regions of the cortex and some structures of the subcortex. This photograph is of special interest because the insectivores are one of the most ancient orders of the placental mammals. This group shows the initial steps in the evolution of the main cortical regions (archicortex, paleocortex and neocortex). This group is also important because the insectivores are the ancestors of the primates.

Organs: сentral nervous system, cerebral brain or its part
