    Study Notes

    Cerebral Cortex Structure

    • Pyramidal cells in the cerebral cortex have a long axis vertical to the surface.

    Cerebral Cortex Characteristics

    • The thickness of the cerebral cortex is approximately 2-3 mm.

    Cell Types in Cerebral Cortex

    • Polygonal cells with multiple branching dendrites are also found in the cerebral cortex.

    Location of Horizontal Cells

    • Horizontal cells of Cajal are located in the molecular layer of the cortex.

    Function of Fusiform Cells

    • Fusiform cells in the cerebral cortex function as interneurons, providing lateral inhibition and regulating the activity of surrounding pyramidal cells.
