The central visual pathways and their functional significance in the mole(Talpa europaea)



Anatomical studies on the visual system of the mole (Talpa europaea) using degeneration techniques, show that the distribution of optic fibres is reduced compared with hedgehog and other mammals. In five of the six moles studied, degeneration after eye removal was found in only the pretectal region and the ventral lateral geniculate body. A behavioural study shows that moles can respond to some visual stimuli and learn a light-dark discrimination.
