Hypothalamic control of the pars intermedia in Xenopus laevis tadpoles.
TLDR
It was concluded that the initial aggregation of the melanophores may be the result of a reduced extrusion of MSH from the pars intermedia, caused by an increased output of a MIF by the bio-amine producing nuclei.Abstract:
In Xenopus laevis tadpoles the relation between a paired nucleus of bio-amine producing neurons in the caudal hypothalamus and the pars intermedia of the hypophysis was studied.read more

TL;DR: Experimental data indicate that the aminergic fibres in the pars intermedia exert an inhibitory influence on MSH-release.

The Role of the Carbohydrate in the Stabilization, Processing, and Packaging of the Glycosylated Adrenocorticotropin-Endorphin Common Precursor in Toad Pituitaries
Peng Y. Loh,Harold Gainer +1 more
TL;DR: The data indicate that glycosylation of the ACTH-endorphin precursor may not be involved in the processes of intracellular transport, packaging, and secretion per se but, rather, may provide specific conformational stability to the precursor as a signal for directed limited proteolysis.

Monoaminergic tracts of the diencephalon and innervation of the pars intermedia in Rana temporaria. A fluorescence and microspectrofluorimetric study.
P. D. Prasada Rao,H. G. Hartwig +1 more
TL;DR: In this paper, two monoaminergic tracts having independent nuclear sources, and extending towards the hypophysis, were identified in the diencephalon of Rana temporaria.

Background adaptation by Xenopus laevis: A model for studying neuronal information processing in the pituitary pars intermedia
TL;DR: The structural and functional aspects of the various neural and endocrine steps in the regulation of skin colour adaptation by Xenopus reveal a high degree of plasticity, enabling the animal to respond optimally to the external demands for physiological adaptation.

Ependyma of the third ventricle in relation to pituitary function.
TL;DR: This chapter presents observations that describe the ependymal wall of the ventral hypothalamus and point to its possible involvement in neuroendocrine control.

Lancelot Hogben,David Slome +1 more
TL;DR: It is now clearly established that the pituitary gland is an essential agency in determining Amphibian colour change, and it is still possible to entertain the hypothesis that the gland is merely a condition of the response of the melanophores to nervous impulse in efferent fibres supplying the skin.

TL;DR: There is support for the hypothesis that these adrenergic fibers mediate the inhibitory control by the brain of the pars intermedia of the frog, Rana temporaria L.

Catecholamine im Hypothalamus vom Goldfisch (Carassius auratus)
H. G. Baumgarten,Heiko Braak +1 more
TL;DR: The hypothalamus of Carassius auratus was investigated by means of the method for fluorescence-microscopical detection of catechol- and tryptamines and it is assumed that the fluorescent substance in the hypothalamus is noradrenaline.
