pyramidal cells

py·ram·i·dal cells

neurons of the cerebral cortex that, in sections perpendicular to the cortical surface, exhibit a triangular shape with a long apical dendrite directed toward the surface of the cortex; there are also lateral dendrites, and a basal axon that descends to deeper layers.

Based on the initial observations of Raymond Cajal, who noted that the CBs are striking nuclear components of the rat brain and, more specifically, the pyramidal cells of the human cerebral cortex [1, 25], we analyzed the nuclear distribution patterns and formation of the CBs in the hippocampus and olfactory bulbs (OBs) of adult mouse brains.
