Anatomy and Synaptology of the Optic Tectum

摘要: After decussation in the chiasma optic fibres become segregated to form accessory tract and main or marginal tract. The anterior part of is supposed connect retina with subthalamic dorsal hypothalamic nuclei [45]. While a few recent observations seem corroborate this early assumption [18, 47–49, 65, 71], bulk opposing data denies existence these connexions [1, 5, 9, 11, 12, 14, 27–29, 34–36, 46, 55, 57, 67, 76]. posterior terminates mesencephalic basis tegmentum (for details see Marg’s Chapter 15, volume). carrying nearly all fibres, different diencephalic tectum. It now known that portion only partially decussates also sub mammalian vertebrates [5, 6, 47, 55]. aim present survey give detailed account tectum its connexions.
