Key takeaways

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

Reference excerpt

Vivien Alice Casagrande (June 7, 1942 – January 21, 2017) was a professor in the Department of Cell and Developmental Biology at the Vanderbilt University Medical Center.

Life Casagrande was born in Belmont, Massachusetts to Erna and Arthur Casagrande in 1942. She received her B.S. in psychology from University of Colorado Boulder in 1964 and then obtained her PhD from Duke University in 1973 in physiological psychology under the direction of Irving T. Diamond.

Career Casagrande did her postdoctoral study at the University of Wisconsin–Madison prior to becoming an assistant professor at Vanderbilt University School of Medicine in 1975. In 1982, Prof. Casagrande became an investigator into the vernal keratoconjunctivitis and held leading positions at VKC. In 1986, Dr. Casagrande became full professor and investigator at the Vanderbilt Brain Institute and at the Vanderbilt Kennedy Center. As an investigator, she had worked as an associate director under guidance from Elisabeth Dykens and interim director, Steve Warren, at the Biomedical Research from 1988 to 1991. From 1989 to 1991 she was also a director of the Neuroscience Core and the Neuroscience Research Cluster, which she left in 1992. From 1997 to 2001, Professor Casagrande had served on the Communications and Chapters Committee of the Society for Neuroscience. In 2006, she served as a chairperson for the National Eye Institute's CDA Review Panel and was on Andrew G. White's thesis committee at the University of Sydney.

Research Casagrande's research focused on understanding how the visual thalamus and cortex interact to construct our perceptual world. She did this through three different projects. Her first project was to analyze the notion that the primary sensor information received by the visual cortex from the visual thalamus is not purely visual, but rather visual information. The second project was to test whether all thalamic nuclei contain some cell groups that act as drivers and some that act as modulators for multiple cortical areas. The third project was to study communication between cells in separate areas of the visual cortex and how visual messages are coded and transmitted from lower to higher visual areas and what the role of feedback is.

Editorial work Casagrande had served on many editorial boards, including for the Cerebral Cortex, Journal of Comparative Neurology and Visual Neuroscience. She also was an assistant editor for the American Journal on Mental Retardation, Journal of Experimental and Integrative Medicine, and Visual Neuroscience.

Awards Casagrande was awarded the Charles Judson Herrick Award (1981) from the American Association of Anatomists and was elected fellow of the American Association for the Advancement of Science (2006) and the American Association of Anatomists (2011). Posthumously, she was inducted into the Patricia Goldman-Rakic Hall of Honor, by the Society for Neuroscience.

Worked examples

Example 1 — a first encounter with Vivien Casagrande

Start with the simplest possible case. Write down what Vivien Casagrande 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 Vivien Casagrande 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 Vivien Casagrande 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 Vivien Casagrande

In research
Vivien Casagrande 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 Vivien Casagrande 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
Vivien Casagrande is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1942 births, 2017 deaths, American neuroscientists, so understanding it makes those chapters shorter.
In everyday life
Look for Vivien Casagrande 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.
