Visual wulst influences on flash evoked responses in the ectostriatum of the zebra finch [PDF]

open access: yes, 1994
Engelage J, Bischof H-J. Visual wulst influences on flash evoked responses in the ectostriatum of the zebra finch. Brain Research. 1994;652(1):17-27.Anatomical data suggest that visual information from the thalamofugal pathway contributes to visual ...

THE REPRESENTATION OF THE RETINA ON THE OPTIC TECTUM OF THE PIGEON [PDF]

open access: yesQuarterly Journal of Experimental Physiology and Cognate Medical Sciences, 1954
1. There is point to point representation of the retina on the optic tectum in the pigeon. The upper visual field is represented on the dorsal surface.2. A response obtained from the first three layers of the optic tectum may have a latency as short as 25 msec., and show little fatigue when the stimulus is repeated at rates of not more than 5 per sec.3.

Visual and Electrosensory Circuits of the Diencephalon in Mormyrids [PDF]

open access: yes, 1990
Mormyrids are one of two groups of teleost fishes known to have evolved electroreception, and the concomitant neuroanatomical changes have confounded the interpretation of many of their brain areas in a comparative context, e.g., the diencephalon, where ...

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.

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 ...

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.

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 ...

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 ...
