Cultural Division of the Sciences and Humanities
We live in a culture where facility with science, facts and numbers are considered left brain activities and creative endeavors like fiction, painting and music are considered right brain activities. Individuals are supposedly trapped into primarily using one half their brain or the other. Further emphasizing this division, college tracks are separated into the humanities or science & technology, with only a smattering of courses allowed on the other side of the aisle. In 1959, C.P Snow—a chemist and novelist—called on the British to stop separating the two cultures and to allow greater crossover. He called the humanists in his country “pessimistic Luddites” and saw the bright future of prosperity and cold war superiority in science—but a humanized science. His short book on the topic became hot in the US as we ramped up our own science and technology for the space age. 1
Left Brain- Right Brain Theories and Handedness
In the 1980s, left brain- right brain theory was popularized and remains so to this day. You can take quizzes online to find out your brain dominance and personality. These theories started with the over-interpretation of a case study involving an epilepsy patient whose corpus callosum was surgically severed to control his seizures. The corpus callosum, Latin for tough body, is a fiber network joining the right and left hemispheres. This surgery helped the patient’s seizures, but messed up his ability to process information and move in a side-specific manner. 2
This myth of right- and left brained people is perpetuated by many factors, including our observations of right- and left-handed people. Lefties comprise only ~10% of the population (and have been since prehistoric days) and are expected to be more creative. Based on that, you would guess that a room full of scientists would all be right-handed and if they were all sitting at tables taking notes, no one would have to worry about bumping elbows. It was after an elbow bump during a meeting tightly packed around a table that I first realized at least half my molecular biology, pharmacology and chemistry colleagues were left-handed. I felt a little left out as a rightie, as if maybe I had a creativity disadvantage. But scientific study does not support this common stereotype 3, and instead some hypothesize left-handedness remains in the gene pool due to an association with competitiveness. 4

Myths and Truths on Left-Right Brain Use
Scientific inquiry over the last 20 years has enabled us to measure the size and activity of different brain regions in living humans and even dogs. Imaging can be done in people who are doing nothing in particular (the default brain network) and while they are engaged in specific tasks. These types of studies have verified that righties have most of their motor functions controlled by the left motor cortex, while lefties have more controlled by the right motor cortex, but with not as much of a preference as righties. That makes it easier for lefties to become ambidextrous and cope with a broken left arm. 5
There are many functions that tend to be more predominant on one side of the brain verses the other (lateralization) and it’s an expanding area of research. More of the functions associated with language are found on the left, while attention and non-verbal communication is more focused in the right brain. But imaging has allowed us to see that for individuals, we are not predominantly using only one side of our brains verses the other outside of our motor functions. 6
The Gorgeous Corpus Callosum
I want to put in a plug here for the beautiful brain and the amazing corpus callosum. It is the largest white matter tract in the brain and allows for exquisite coordination of left and right hemispheres. It’s only found in placental mammals and the complex lateralization and interplay between hemispheres in humans is not found in mouse brains, the species I most studied. The corpus callosum and its complexity are part of what makes us human.
So now that we’ve got the handedness and left-right brain story a little bit explained, what about a scientist becoming a successful novelist? Most people would think the link with science fiction was pretty reasonable. Andy Weir, author of The Martian, is a computer programmer who we can put into the analytical scientist bucket. But many would be surprised at the inclusion of Vladimir Nabokov and Lewis Carroll on the list. Contemporary biologist/authors of other types of fiction include:
- Diana Gabaldon- the Outlander series
- Barbara Kingsolver- The Poisonwood Bible, The Bean Trees, The Lacuna
- Delia Owens- Where the Crawdads Sing
- Lisa Genova- Still Alice, Inside the O’Briens, Love Anthony
- Brandon Taylor- Real Life
Many physicians and psychologists are also successful authors and there’s even a website at NYU that helps you find not only medically oriented authors but also good literature including science. https://medhum.med.nyu.edu/ Think about Anton Checkov, William Carlos Williams, W. Somerset Maugham, Abe Kobo and Percy Walker in an earlier era. More modern physician/authors include:
- Kaled Hosseini- The Kite Runner, A Thousand Splendid Suns
- Abraham Verghese- Cutting for Stone
- Chris Cleve– Little Bee, Everyone Brave is Forgiven, Incendiary
- Irvin Yalom- Lying on the Couch, When Nietzsche Wept, The Spinoza Problem
- Carol Cassella- Oxygen, Healer, Gemini
- Perri Klass- The Mercy Rule, The Mystery of Breathing
- Melissa Yuan-Innes/ Melissa Yi- Code Blues, Life Support, Terminally Ill
- Tess Gerritsen- Girl Missing, The Apprentice, The Bone Garden
The works of these authors span genres and although many include significant components of their scientific/medical expertise, many do not. You’ll find little bits in my novels, and I hope to join the ranks of these distinguished published authors soon.

Your story is an inspiration for so many young women including my daughters. Thank you for allowing us be part of this new journey!
Thanks Gilda. I think we’re even because both you and your daughters inspire me!
