S. T. Narasimhan

S. T. Narasimhan 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 S. T. Narasimhan rather than just read about it. In short: S. T.

Key takeaways

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

Reference excerpt

S. T. Narasimhan (1913 – 1959) was an Indian electrophysiologist. He started the first Electroencephalography (EEG) laboratory in India at Madras (now Chennai) in 1950. He was best known for collaborative works with neurologists Jacob Chandy, Balasubramaniam Ramamurthi and Baldev Singh and together they have been credited to be pioneers in development of epilepsy surgery in India. They also helped in establishing the Neurological Society of India in 1951 at Madras.

Life Not much is known about the life of Narasimhan; but Balasubramaniam Ramamurthi's biography Uphill All The Way gives some details. Narasimhan was born in 1913, and around 1945 he sold his medical practice in India so he could go to the United States of America to further his studies. He was a General Surgeon and at the Neurological Institute of New York he trained in neurology and neurosurgery. He returned to India in 1948 and started his private practice setting up a neurosurgical nursing home and EEG laboratory and stayed in the residential areas of Kilpauk, Chennai. Dr. Balasubramaniam had set up the Department of Neurosurgery at the Government General Hospital, Chennai in 1950 and Narasimhan joined him as an honorary assistant surgeon. During the pioneering days, X-rays and EEG were used in diagnosis as angiography was not yet available in India. During the neurosurgical procedures that Balasubramaniam under took, Narasimhan assisted him in EEG service and in later patient care. Narasimhan earned around ₹30 (equivalent to about ₹3,170 in 2023) for each procedure from the then Government of Madras. In 1951, Singh, Chandy, Ramamurthi and Narasimhan established the Neurological Society of India and together find credit as pioneers of epilepsy surgery in India. In 1959, Narasimhan became the Honorary Professor of Electroencephalography. The same year, he died at an early age of 46 at Bangalore of unknown reasons.

Worked examples

Example 1 — a first encounter with S. T. Narasimhan

Start with the simplest possible case. Write down what S. T. Narasimhan 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 S. T. Narasimhan 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 S. T. Narasimhan 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 S. T. Narasimhan

In research: S. T. Narasimhan 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 S. T. Narasimhan 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: S. T. Narasimhan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1913 births, 1959 deaths, 20th-century Indian medical doctors, so understanding it makes those chapters shorter.
In everyday life: Look for S. T. Narasimhan 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.
