  • The theory of the reaction was now established and it agreed absolutely with the theory of both Breuer and Mach which had recognized the movements of the endolymph, the fluid contained in the semi-circular canals, as being the cause of stimulation in them.

  • The decisive factor was the temperature of the syringing fluid and it was soon also clear that the phenomenon, the so-called caloric reaction, proceeded from the semi-circular canals, in which the endolymph increases in specific gravity with cooling, showing a tendency to sink, whereas with warming the specific gravity decreases and the fluid shows a tendency to rise.

  • He established an unquestionable connection between specifically directed head and eye movements of the animal with specifically directed movements of the endolymph in the semi-circular canals.

    Robert Bárány - Nobel Lecture

  • Flourens's experiments with pigeons with improved technique and came directly to the conviction that movement of the fluid in the semi-circular canals, the endolymph, gave rise to the Flourens phenomena.

    Robert Bárány - Nobel Lecture

  • The flux, or tendency to flux, which then appears in the endolymph of the semi-circular canals produces the reaction.

  • He then set himself the task of establishing the site of the central mechanism governing the movements of the eyes, the nystagmus already referred to, which is set in motion by the movement of the endolymph.

    Robert Bárány - Nobel Lecture

  • The membranous bag itself contains a similar fluid, the _endolymph_.

    A Practical Physiology

  • When, therefore, the perilymph is shaken it communicates the impulse to the fluid (endolymph) contained in the inner membranous bag.

    A Practical Physiology

  • The inner portion, called the _membranous labyrinth_, consists essentially of a closed membranous sac, which is filled with the endolymph.

  • The endolymph and the tiny grains of ear-sand now perform their part in this marvelous and complex mechanism.
