Otfrid Foerster is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Otfrid Foerster rather than just read about it. In short: Otfrid Foerster (German: [ˈfœʁstɐ]; 9 November 1873 – 15 June 1941) was a German neurologist and neurosurgeon, who made innovative contributions to neurology and neurosurgery, such as rhizotomy for the treatment of spasticity, anterolateral cordotomy for pain, the hyperventilation test for epilepsy, Foerster's syndrome, the first electrocorticogram of a brain tumor, and the first surgeries for epilepsy. He also made…

Key takeaways

  • Otfrid Foerster belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Otfrid Foerster to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Otfrid Foerster from memory before moving on to harder problems.

Reference excerpt

Otfrid Foerster (German: [ˈfœʁstɐ]; 9 November 1873 – 15 June 1941) was a German neurologist and neurosurgeon, who made innovative contributions to neurology and neurosurgery, such as rhizotomy for the treatment of spasticity, anterolateral cordotomy for pain, the hyperventilation test for epilepsy, Foerster's syndrome, the first electrocorticogram of a brain tumor, and the first surgeries for epilepsy. He also made influential contributions in advancing knowledge of dermatomes (an area of skin that is supplied by a single pair of dorsal nerve roots), building upon previous work of Herringham, Thorburn, Sherrington, and others. He also helped map the motor cortex of the cerebrum.

Life

Foerster was born in Breslau (now Wrocław) to Richard Foerster, and studied in the Maria Magdalenen Gymnasium, graduating 1892. From 1892 to 1896 he studied medicine in Freiburg, Kiel and Breslau, obtaining his licensure by state examination in 1897 and his doctorate in the same year. Upon completion of the doctoral studies, he spent two years studying abroad, following a suggestion by Karl Wernicke (1848-1905): in the summer he went to Paris, studying with Joseph Jules Dejerine and attending classes by Pierre Marie and Joseph Babinski (1857-1932); and in the summer with Heinrich Frenkel in Switzerland, in order to study physical therapy of neurological patients there.

Foerster's student years occurred in a time when neurology was starting to develop independently from internal medicine and psychiatry under the influence of, among others, Jean-Martin Charcot (1825-1893), Wilhelm Heinrich Erb, William Richard Gowers (1845-1912) and particularly Karl Wernicke, who became well known by his direction toward functional localization approaches. By cooperating with Wernike, Foerster's great interest on the anatomy of the central nervous system was excited. The two researchers published together in 1903 an anatomical atlas of the brain (Atlas des Gehirns). At the time, the several schools of neurology were focused essentially on to diagnosis; because achieving an effective therapy was hardly possible. It was Foerster who took forward the idea of using physical therapy as a new way of treating patients with neurological disturbances. From this work arose his theoretical interest on the disturbances of motor coordination in the execution of movements: this resulted in the topic of his dissertation in 1902, a work which attained a great actuality in connection with the systematic introduction of rehabilitation medicine into neurology. The involvement of spinal reflexes in the genesis of muscular spasticity suggested its possible treatment by surgical interruption of the sensory branch of the thoracic and lumbar nerves (rhizotomy), and Foerster developed in 1908 an operation to cut the posterior sensory root in order to alleviate spasticity. In 1915 Foerster first reported on his innovative results concerning the surgical treatment of nerve damage by shot wounds, as well as other kinds of spinal cord and brain damage. From 1922 to 1924 Foerster went to Russia as he attended Lenin after his stroke. When his most famous patient died, he was asked to suggest a scientist who could examine Lenin’s brain after the autopsy. He recommended Oskar Vogt. As the most important of all the foreign consultants, his signature appeared on all the documents about the treatment and the death of Lenin. Even if he has not cooperated with the National Socialists, his finances were restricted and his professional activities curtailed. He was put under surveillance by the german authorities. This was due to : his past connections to Lenin; the fact that his wife was partly Jewish; and the 1932's Rockefeller Foundation grant, urged by Foerster’s American friends, who funded the modern laboratory building of the Institute of Neurology. In 1934, the same year the building was built, he was deprived of his extraordinary professorship and in 1938 was relieved of the function of university professor. In the time between the two world wars (1925 to 1935) Breslau became a place of attraction for training neurologists and neurosurgeons, particularly those coming from the United States. One of his early students coming from that part of the world was Wilder Penfield (1891-1976), who continued Foerster's work on the analysis of the cerebral cortex's command of movement and the study of epilepsy. Other students were Percival Bailey, who developed a new classification of brain tumors, and Paul Bucy, discoverer of the famous Klüver-Bucy syndrome, who made fundamental work on the organization of motor cortex, and Robert Wartenberg (1897-1956, discoverer of the Wartenberg's syndrome). Other eminent visitors were Alfred Adson, Max Peet, Edgar Kahn, John Fulton and Margaret Kennard. One of Foerster's important methods was to use local anaesthesia to keep brain surgery patients awake. While they lay there, Foerster would poke at their brain with an electronic needle, and use the subsequent motor reactions (hand movement, finger movement, etc.) to learn about the brain's motor cortex. He received the Hughlings Jackson Memorial Medal, which he cherished the most of all his academic honors during the second International Neurological Congress in London in 1935. But he received no single German honor between 1933 and his death. Foerster died in 1941 in Breslau, at age 67.

Worked examples

Example 1 — a first encounter with Otfrid Foerster

Start with the simplest possible case. Write down what Otfrid Foerster claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Otfrid Foerster before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Otfrid Foerster ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Otfrid Foerster

In research
Otfrid Foerster appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Otfrid Foerster in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Otfrid Foerster is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1873 births, 1941 deaths, German neurologists, so understanding it makes those chapters shorter.
In everyday life
Look for Otfrid Foerster outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
