Connections of the corpus cerebelli in the green sunfish and the common goldfish [PDF]

open access: yes, 1988
Examination of the connections of the corpus cerebelli in one perciform (Lepomis cyanellus) and one cypriniform teleost (Carassius auratus) reveal that ipsilateral afferent connections in both species arise from an anterior group of nuclei in the ...

A simple non-invasive method for measuring gross brain size in small live fish with semi-transparent heads [PDF]

open access: yesPeerJ, 2014
This paper describes a non-invasive method for estimating gross brain size in small fish with semi-transparent heads, using system camera equipment. Macro-photographs were taken from above on backlit free-swimming fish undergoing light anaesthesia.

The avian tectobulbar tract: development, explant culture, and effects of antibodies on the pattern of neurite outgrowth [PDF]

open access: yes, 1990
The tectobulbar tract is the first long-distance projecting fiber pathway to appear during the development of the avian optic tectum (dorsal half of the mesencephalon).

ELECTROPHYSIOLOGICAL INVESTIGATIONS ON THE PIGEON'S OPTIC TECTUM [PDF]

open access: yesQuarterly Journal of Experimental Physiology and Cognate Medical Sciences, 1971
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 ...

Optic nerve regeneration in larval zebrafish exhibits spontaneous capacity for retinotopic but not tectum specific axon targeting.

open access: yesPLoS ONE, 2019
In contrast to mammals, retinal ganglion cells (RGC) axons of the optic nerve even in mature zebrafish exhibit a remarkable capacity for spontaneous regeneration.

Mapping neurogenesis onset in the optic tectum of Xenopus laevis. [PDF]

open access: yesDev Neurobiol, 2016
Neural progenitor cells have a central role in the development and evolution of the vertebrate brain. During early brain development, neural progenitors first expand their numbers through repeated proliferative divisions and then begin to exhibit ...

FGF2 delays tectal neurogenesis, increases tectal cell numbers, and alters tectal lamination in embryonic chicks. [PDF]

open access: yesPLoS ONE, 2013
Intraventricular injections of the fibroblast growth factor 2 (FGF2) are known to increase the size of the optic tectum in embryonic chicks. Here we show that this increase in tectum size is due to a delay in tectal neurogenesis, which by definition ...

A contribution to the study of the afferents to the pigeon optic tectum [PDF]

open access: yesAnatomy and Embryology, 1982
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.

Midbrain morphogenesis in beluga sturgeon (Huso huso) larvae [PDF]

open access: yesBulgarian Journal of Veterinary Medicine, 2018
The subject of this study was the development of midbrain in beluga sturgeon (Huso huso) larvae. To this end, 36 larvae (6 larvae of each age) were fixed in 10% buffered formalin, dehydrated in an etha-nol series, cleared in xylene and embedded in ...
