Methylene blue supravital staining: an evaluation of its applicability to the mammalian brain and pineal gland.

Methylene blue supravital staining of mammalian brain reveals typical staining patterns in different brain regions and indicates a certain vulnerability to hypoxia; the intracellular dye-uptake might be interpreted as an early sign of metabolic disturbance.

A correlative study of the physiology and morphology of the retinotectal pathway of the perch

The anatomy and physiology of the retinotectal pathway of the perch was investigated using physiological and histological techniques, and effects of electrical stimulation or cautery of the tectum on the flash-evoked response of fiber bundles, via the efferents were marginal.



Experiments on Vital Staining with Methylene Blue

Determinations of the solubility of leucomethylene blue and experiments on vital staining with it and with the oxidized dye at different pH values are consistent with the hypothesis that the dye penetrates cell membranes and tissues mainly as the leucobase, but may pass along nerve (and muscle) fibres in the oxidization form.

The fine structure of autonomic nerves after vital staining with methylene blue

Experiments with M B thiocyanate and M B chloride in phosphate‐citrate or succinate‐HCl buffer indicated that purity of dyestuff was less important than pH control, and methods for electron‐microscopical demonstration of acetylcholinesterase are more useful for distinguishing cholinergic axons.


The reflecting cells on the scales of sprat and herring contain ordered arrays of guanine crystals which determine the wave bands of the light which they reflect, hence volume changes in the reflecting cells can be observed as color changes directly.

Muscle Receptor Organs in the Abdomen of Homarus vulgaris and Palinurus vulgaris

The hypothesis is put forward that they might come into action during vigorous movements of the abdomen in the escape reaction of the animal, and may perhaps convey inhibitory impulsesto the elements causing the rapid contractions of the flexor muscles.
