Josef Breuer - Other Work

Other Work

Breuer, working under Ewald Hering at the military medical school in Vienna, was the first to demonstrate the role of the vagus nerve in the reflex nature of respiration. This was a departure from previous physiological understanding, and changed the way scientists viewed the relationship of the lungs to the nervous system. The mechanism is now known as the Hering–Breuer reflex.

Independent of each other in 1873, Breuer and the physicist and mathematician Ernst Mach discovered how the sense of balance (i.e., the perception of the head’s imbalance) functions: that it is managed by information the brain receives from the movement of a fluid in the semicircular canals of the inner ear. That the sense of balance depends on the three semicircular canals was discovered in 1870 by the physiologist Friedrich Goltz, but Goltz did not discover how the balance-sensing apparatus functions.

In 1894, Breuer was elected a Corresponding Member of the Vienna Academy of Science.

Famous quotes containing the word work:

    The gold-digger is the enemy of the honest laborer, whatever checks and compensations there may be. It is not enough to tell me that you worked hard to get your gold. So does the Devil work hard. The way of transgressors may be hard in many respects.
    Henry David Thoreau (1817–1862)

    The best work of artists in any age is the work of innocence liberated by technical knowledge. The laboratory experiments that led to the theory of pure color equipped the impressionists to paint nature as if it had only just been created.
    Nancy Hale (b. 1908)
