| Midbrain, also called mesencephalon, region of the developing vertebrate brain that is composed of the tectum and tegmentum. |
| However, expression appeared to be greater in the cerebellum, ectostriatum, paleostriatum, and layers of the optic tectum, suggesting regional differences in regulation. |
| In posterior sections the cartilage assumes a dorsolateral position, ventral and slightly lateral to the tectum nasi. |
| Two non-sensory control regions were examined, the optic tectum and the mesencephalic tegmentum. |
| Infrared and visual organization of the tectum of boid snakes. |
| Fiber connections of the torus longitudinalis and optic tectum in holocentrid teleosts. |
