optic tectum
A region of the midbrain in which input from the optic nerve is processed. Because the retinally derived neurons of the optic nerve "map" onto the optic tectum in a defined way, the question of how this specificity is determined has been a long-standing problem in cell biology. Although there is some evidence for adhesion gradients and for some adhesion specificity, the problem is unresolved.
