Peter Milner

Peter Milner 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 Peter Milner rather than just read about it. In short: Peter Milner (13 June 1919 – 2 June 2018) was a British-Canadian neuroscientist and former electrical engineer. He spent most of his career in the Department of Psychology at McGill University in Montreal, where, together with James Olds, he helped establish the study of electrical self-stimulation of the brain and the neural basis of reward.

Key takeaways

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

Reference excerpt

Peter Milner (13 June 1919 – 2 June 2018) was a British-Canadian neuroscientist and former electrical engineer. He spent most of his career in the Department of Psychology at McGill University in Montreal, where, together with James Olds, he helped establish the study of electrical self-stimulation of the brain and the neural basis of reward.

Biography Milner was born in Silkstone Common and grew up in Barnsley, South Yorkshire, England. His father was David William Milner, a research chemist, and his mother was Edith Anne Marshall, an ex-schoolteacher. After graduating in electrical engineering from the University of Leeds in 1941, he joined the United Kingdom's Air Defence Research and Development Establishment, where he worked on radar display systems during the Second World War. In 1944 he moved to Canada to work on nuclear energy research at the Chalk River Laboratories in Ontario. He was an electrical engineer, but became interested in neuroscience while his wife Brenda Milner was studying the subject at McGill University; he became a graduate student with the same supervisor as her, and later taught at McGill himself. In collaboration with James Olds, he is credited with the discovery of the pleasure centre and the pain centre in the brains of rats. In his 1974 article "A Model For Visual Shape Recognition" Milner mentions a popular hypothesis suggesting that the features of individual objects are segregated and bound by means of synchronization of the activity of different neurons in the cortex. The theory, termed binding-by-synchrony (BBS), is hypothesized to occur through the transient mutual synchronization of neurons located in different regions of the brain when the stimulus is presented. Milner received the Gold Medal for Distinguished Lifetime Contributions to Canadian Psychology from the Canadian Psychological Association in 2005. Milner died on 2 June 2018 at Centre hospitalier de l'Université de Montréal in Montréal.

Worked examples

Example 1 — a first encounter with Peter Milner

Start with the simplest possible case. Write down what Peter Milner 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 Peter Milner 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 Peter Milner 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 Peter Milner

In research: Peter Milner 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 Peter Milner 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: Peter Milner is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1919 births, 2018 deaths, British emigrants to Canada, so understanding it makes those chapters shorter.
In everyday life: Look for Peter Milner 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.
