non-mammalian vertebrates, the homologous structure is known as the optic tectum or optic lobe. The adjective form tectal is commonly used for both structures...

vertebrates including fish and amphibians, is called the optic tectum; in those animals, the optic tectum integrates sensory information from the eyes and certain...

the contralateral optic tectum. In boas and pythons, information from the labial pit is sent directly to the contralateral optic tectum via the lateral...

does not retrieve a branch from the optic tract but only from the contralateral optic tectum, so that the optic path decussates twice, and the forebrain...

in the optic tectum include widefield arousal neurons, binocular neurons, and approach-sensitive neurons. As explained above, the optic tectum is responsible...

looping occurs, for example, in the optic tract between the optic chiasm and the optic tectum. Another example is the optic radiation which rotates the retinal...

Beyond the optic chiasm, with crossed and uncrossed fibers, the optic nerves are called optic tracts. The optic tract inserts on the optic tectum (in mammals...

central nervous system that lie behind the twist. The optic nerve inserts on the optic tectum of the midbrain. In tetrapods and bony fish it also branches...

not limited to the retina, the dorsal lateral geniculate nucleus, the optic tectum, the primary visual cortex (V1), and higher visual areas (V2-V4). Retinotopic...

Optic lobe refers to brain structures involved in vision: The superior colliculus of mammals or the analogous optic tectum of other vertebrates, structures...

and the locus coeruleus. The LGN also receives some inputs from the optic tectum (known as the superior colliculus in mammals). These non-retinal inputs...

toad's visual field, information is sent to the optic tectum in the toad's midbrain. The optic tectum exists as an ordered localization system, in the...

vertebrates, this saliency map is more likely in the superior colliculus (optic tectum). Certain automatic responses that influence attention, like orienting...

if the owl’s optic tectum was inactivated, then the owl’s brain would have changes in the auditory orienting behavior. As the optic tectum is involved...

recordings were made from the optic tectum. Consistent with the previous findings regarding the organization of the optic tectum in terms of elevation and...

due to social deprivation, the formation of dendritic branches in the optic tectum was arrested as was the experience-based shortening of dendritic spine...
