Visual recovery in goldfish following unilateral optic tectum ablation : Evidence of competition between optic axons for tectal targets [PDF]

open access: yes, 1984
Anatomical studies suggest that regenerating optic axons which invade the ipsilateral lobe of the optic tectum following ablation of the contralateral lobe compete with resident optic axons for synaptic sites on tectal neurons.

Supplementary Material for: Allometric Scaling of the Optic Tectum in Cartilaginous Fishes

open access: yes, 2017
In cartilaginous fishes (Chondrichthyes; sharks, skates and rays (batoids), and holocephalans), the midbrain or mesencephalon can be divided into two parts, the dorsal tectum mesencephali or optic tectum (analogous to the superior colliculus of mammals ...

The developing chick isthmo-optic nucleus forms a transient efferent projection to the optic tectum

open access: yes, 1990
The present work describes the formation of a transient efferent axonal projection from the isthmo-optic nucleus (ION) to the ipsilateral optic tectum of the chick embryo. Local application of either the carbocyanine dye DiI or rhodamine-B-isothiocyanate

Characterization of CRF immunoreactive neurons in the anuran optic tectum

open access: yes, 2008
In amphibians, it has been determined that CRF has an affect on subcortical visual pathways that regulate prey capturing ability. The pathways targeted by CRF effects on visually guided feeding are unknown, but CRF-ir fibers have been reported in the ...

Operant Discriminative Learning and Evidence of Subtelencephalic Plastic Changes After Long-Term Detelencephalation in Pigeons

open access: yesNeural Plasticity, 2003
We analyzed operant discrimination in detelencephalated pigeons and neuroanatomical substrates after long-term detelencephalation. In Experiment I, experimental pigeons with massive telencephalic ablation and control pigeons were conditioned to key peck ...

Wulst efferents in the little owl Athene noctua: An investigation on the projections upon the optic tectum

open access: yes, 1992
The efferent projections from the Wulst were studied in the little owl, Athene noctua, using anterograde migration of wheat-germ-agglutinin conjugated horseradish peroxidase (WGA-HRP). Wulst projections were distributed to telencephalic, diencephalic and
