Cerebellar afferents in the frogs, Rana esculenta and Rana temporaria

Cell and Tissue Research, 1984
Afferents to the cerebellum in frogs (Rana esculenta, Rana temporaria) were studied by use of retrograde transport of horseradish peroxidase. Following injections restricted to the molecular layer of the cerebellum cell labelling was found in the contralateral inferior olive and the ventral portion of the caudal medullary raphe.

Retinoscopic and neurophysiological refractometry in rana temporaria

Pfl�gers Archiv European Journal of Physiology, 1972
If frogs are measured by objective refractometry one finds a hyperopia of 6 D to 9 D. Therefore we investigated the neurophysiological state of refraction of the immobilized rana temporaria using the technique of extracellular recording. In the superficial neuropil the neural activity of 32 recorded neurons showed no dependence on the state of ...

Toxicity of tetrachlorwinfos to Rana temporaria l.

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1993
1. Changes in the erythrocyte system of frogs poisoned with tetrachlorwinfos depend on the sex of the animals and the dose of pesticide applied. They are a result of the pathomorphological changes due to translocation of fluids from the tissues to the circulation and swelling of the blood cells. 2. Changes in the leucocyte system of frogs are caused by

Temperature and immobility reaction in Rana temporaria

Behavioural Processes, 1982
Experiments were conducted on two groups of Rana temporaria acclimatized to 7°C and to 14°C. Two hours prior to the experiments the animals were divided into six groups of 40 subjects each and placed in containers at temperatures of 5°, 10°, 15°, 20°, 25° and 30°C.

Albinism inRana temporaria

Journal of Genetics, 1949
White frog spawn gave rise to black-eyed white tadpoles, which later darkened, and developed into normal frogs. The latter produced normal tadpoles, some of which developed into albino adults. The facts can be explained if albinism is recessive, but the dominant allelomorphic gene found in normal frogs produces enough pigment in the eggs of ...

Action of Insulin on the Frog (Rana temporaria)

Nature, 1953
EARLIER investigations of the action of insulin on cold-blooded vertebrates have shown that, although large doses usually lead to the appearance of typical convulsions, there is often a long latent period (1–2 days at room temperature) during which there are no visible symptoms1–3. In experiments performed in March and May 1952 the action of insulin on
