Joseph Hippolyte Cloquet (1787–1840)—Physiology of smell

While the physiology, histology and stem cell biology of smell are active fields of contemporary research, smell is probably the sense that physicians knew the least about prior to the 20th century. Joseph-Hippolyte Cloquet (1787–1840) was an anatomist who, in 1815, defended a singular doctoral thesis—On odours, the sense of olfaction and the olfactory organs—then went on to publish, in 1821, t...

Recent concepts about sense of smell, odorant receptors and physiology of olfaction- an insight

The sense of olfaction reached its zenith in development much earlier than other special senses. Olfaction is much more acute than the other senses, exhibits both high sensitivity for odours and high discrimination between them. This plays a very important role even in the social and behavioral aspects of human beings. Recent studies using molecular genetics, electrophysiology and behavioral an...

Postage stamps of ophthalmological interest.

POSTAGE stamps of ophthalmological interest include portrait figures of two practising ophthalmologists, Ferdinand Ritter von Arlt (1812-87) and Franz Cornelius Donders (1818-89). Four further portrait figures of scientists who have directly or indirectly contributed greatly to ophthalmology are shown in the stamps commemorating Johannes Evangelista Purkinje (1787-1869), Hermann von Helmholtz (...

Reminiscing about Jan Evangelista Purkinje: a pioneer of modern experimental physiology.

This article reminisces about the life and key scientific achievements of Jan Evangelista Purkinje (1787-1869), a versatile 19th century Czech pioneer of modern experimental physiology. In 1804, after completing senior high school, Purkinje joined the Piarist monk order, but, after a 3-yr novitiate, he gave up the religious calling "to deal more freely with science." In 1818, he earned a Medica...
