1. The thalamic-pretectal region initiates avoidance behavior in the toad. 2. Most of these fibers synapse in the lateral geniculate nucleus or the pretectal nucleus. 3. The pretectal area is seven unique nuclei. 4. Pretectal lesions impaired the prey-selectivity.5. Pretectal nuclei, in particular the NOT, are involved in coordinating eye movements during smooth pursuit.6. Lesioning experiments led to the discovery of pathways extending between the tectum and the thalamic-pretectal region. 7. Some important structures directly impacted by the light-sleep relationship are the superior colliculus-pretectal area and the. 8. A pineal tumour can compress the superior colliculi and pretectal area of the dorsal midbrain, producing Parinaud's syndrome. 9. When the thalamic-pretectal region was removed, avoidance behavior was entirely absent while orienting behavior was enhanced even to predator stimuli. 10. Anterior, posterior and medial pretectal nuclei inhibit pain ( indirectly ), aid in REM, and aid the accommodation reflex, respectively.
