A contribution to the study of the afferents to the pigeon optic tectum [PDF]
The origins of several afferent pathways to the pigeon's tectum were studied using the horseradish peroxidase tracing technique. The results confirm the presence of several previously described afferents, and add further data on intertectal and hyperstriatofugal projections.

ELECTROPHYSIOLOGICAL INVESTIGATIONS ON THE PIGEON'S OPTIC TECTUM [PDF]
Electrical responses of the cells at different depths of the pigeon's optic tectum to different visual stimuli were recorded.Point to point representation of the upper visual field on the dorsal surface of the tectum was obtained as a projection on a horizontal stereotaxic plane.Different units in the stratum griseum et fibrosum superficiale of the ...

Effect of retinal ablation on the expression of calbindin D28k and GABA in the chick optic tectum
The effect of retinal ablation on qualitative and quantitative changes of calbindin D28k and GABA expression in the contralateral optic tectum was studied in young chicks.

Proteomic Analyses of Zebra Finch Optic Tectum and Comparative Histochemistry
Proteomic analyses of zebra finch (Taeniopygia guttata) optic tectum resulted in identification of 176 proteins. In the Swissprot database, only 52 proteins were identified as bird homologs and only 71 proteins were identified in songbird transcriptome ...

HISTOLOGICAL STUDY ON OPTIC TECTUM IN IRAQI WATER SNAKE TESSELATA TESSELATA
The ceiling of the midbrain has a couple of optic lobes which are prominent and used as an optic center that reflex what it receives from eye retina fibers.

Neurogenesis of retinal ganglion cells is not essential to visual functional recovery after optic nerve injury in adult zebrafish. [PDF]
Zebrafish central nervous system (CNS) possesses a strong neural regeneration ability to restore visual function completely after optic nerve injury (ONI).

Summary: The brain is spontaneously active, even in the absence of sensory stimulation. The functionally mature zebrafish optic tectum shows spontaneous activity patterns reflecting a functional connectivity adapted for the circuit’s functional role and ...
