Nerve Cells (image) University of Zurich Caption This image shows nerve cells in the primary somatosensory area (S1) of the mouse's cerebral cortex. Cells dyed violet project to the secondary somatosensory area (S2), cells dyed blue to the motor cortex (M1). The strength of the schematic representation of the communication between the areas depends on the tasks to be performed: Left, sandpaper differentiation; right, localization problem.
