| tectal nucleus | The most medial of the cerebellar nuclei, lying medial to the interpositus nucleus, near the midline, in the white matter underneath the vermis of the cerebellar cortex. It receives the axons of Purkinje cells from all parts of the vermis. Its major projection is to the vestibular nuclei and medullary reticular formation. Synonym: nucleus fastigii, fastigatum, nucleus tecti, roof nucleus, tectal nucleus. (05 Mar 2000) |
| tectal stria | A thin longitudinal band of nerve fibres accompanied by gray matter, near each outer edge of the upper surface of the corpus callosum under cover of the cingulate gyru. Synonym: stria longitudinalis lateralis, stria tecta, tectal stria. (05 Mar 2000) |
| retino tectal connection | A problem that has exercised developmental biologists is the way in which nerve fibres from the developing retina are mapped on to the tectum of the brain. There seems to be a good positioning system in operation and a variety of mechanisms probably operate, including control of the fasciculation of fibres in the optic nerve and some specific recognition of the correct target area by the nerve growth cone.
