Key takeaways

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

Reference excerpt

George K. Aghajanian (April 14, 1932 – July 4, 2023) was an American psychiatrist who was Emeritus Foundations Fund Professor at the Yale School of Medicine, New Haven, Connecticut, in the Department of Psychiatry. He was a pioneer in the area of neuropharmacology. He also served as a member of the NARSAD Scientific Advisory Board.

Early life and education George Aghajanian was of Armenian descent and was born on April 14, 1932, in Beirut, Lebanon. He received his B.A. from Cornell University, followed by his Doctor of Medicine at Yale University.

Career Aghajanian was a medical officer in the United States Army in the starting days of his career. He served different positions at the Yale School of Medicine, including assistant professor of psychiatry, professor of psychiatry and pharmacology, and Foundations Fund professor of research in psychiatry. George Aghajanian died on July 4, 2023, at the age of 91.

Research Aghajanian investigated the actions of LSD by which it produces hallucinations in the brain, and uncovered the therapeutic mechanism of atypical antipsychotic drugs. He also found that application of serotonin (5-HT) produces an increase in the frequency and amplitude of spontaneous excitatory postsynaptic potentials in layer V pyramidal cells of the neocortex and transitional cortex by whole-cell recording in rat brain slices. He did further research on the structure and mechanism of psychotropic drugs and neurotransmitters.

Awards and honors Aghajanian received the CINP Pioneer Award from the International College of Neuropsychopharmacology. He also received the Lieber Prize for research on schizophrenia. Additional awards include the Daniel H. Efron Research Award and the Julius Axelrod Mentorship Award from the American College of Neuropsychopharmacology, the Scheele Award from the Swedish Academy of Pharmacy, the Heffter Award from the Heffter Research Institute, and election to the National Academy of Medicine.

Worked examples

Example 1 — a first encounter with George Aghajanian

Start with the simplest possible case. Write down what George Aghajanian 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 George Aghajanian 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 George Aghajanian 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 George Aghajanian

In research: George Aghajanian 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 George Aghajanian 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: George Aghajanian is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1932 births, 2023 deaths, American medical researchers, so understanding it makes those chapters shorter.
In everyday life: Look for George Aghajanian 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.
