Where Does Creativity Come From?
Dr. Eric Kandel is University Professor and Fred Kavli Professor and Director of the Kavli Institute for Brain Science at the Columbia University College of Physicians and Surgeons. His most recent book is The Age of Insight: The Quest to Understand the Unconscious in Art, Mind, and Brain, from Vienna 1900 to the Present.
By probing the synaptic connections between nerve cells in the humble sea slug, Eric Kandel has uncovered some of the basic molecular mechanisms underlying learning and memory in animals ranging from snails to flies to mice and even in humans. His groundbreaking studies have demonstrated the fundamental ways that nerve cells alter their response to chemical signals to produce coordinated changes in behavior. This work is central to understanding not only normal memory but also dementia and other mental illnesses that affect memory.
Kandel's research has shown that learning produces changes in behavior by modifying the strength of connections between nerve cells, rather than by altering the brain's basic circuitry. He went on to determine the biochemical changes that accompany memory formation, showing that short-term memory involves a functional modulation of the synapses while long-term memory requires the activation of genes and the synthesis of proteins to grow new synaptic connections. For this work, the Austrian-born Kandel was awarded the 2000 Nobel Prize in Physiology or Medicine.
The traumatic events of Kandel's childhood likely influenced his later interest in the biological mechanisms of memory. He was only eight when, in 1938, Nazi Germany annexed his homeland, but the humiliation and discrimination that Kandel, his family, and other Jews suffered under this oppressive regime were forever seared into his memory. In 1939, on the eve of World War II, his family fled Austria for the United States.
As a college student at Harvard, Kandel majored in history and literature, but he was drawn to psychoanalysis after befriending a native Austrian student whose parents were prominent psychoanalysts in Sigmund Freud's circle. Kandel went to medical school at New York University with the goal of studying psychiatry and becoming a psychoanalyst himself. But thinking that he should know more about how the brain works, he took a neurophysiology course that shifted his interest toward research into the biology of memory. "The cell and molecular mechanisms of learning and memory struck me as a wonderful problem to study … It was clear to me even then that learning and memory were central to behavior, and thus to psychopathology and to psychotherapy," Kandel recalled.
Initially, he focused on recording the activity of nerve cells in the hippocampus, a region of the brain vital to memory formation. The mammalian hippocampus, however, with its seemingly infinite number of neurons and synaptic connections, made it difficult to study learning and memory at the cellular level. Kandel soon realized he needed a simpler system and chose the invertebrate sea slug Aplysia, much to the dismay of his colleagues who thought that no self-respecting neurophysiologist would abandon the study of learning in mammals to work on an invertebrate.
This bold decision paid off, though, and Kandel now works to instill in his students a sense that risk-taking is important to good science. "I try to convey to students my love of science and my conviction that exploring the biology of the brain is an unmatched scientific adventure," he explained. "I also encourage them to think boldly and to work carefully; to take gambles on their ideas and to try new approaches. I also tell them never to be embarrassed in exposing their ignorance … We are all here to learn, and the learning never ends."
More recently, Kandel has expanded his studies of simple learning and memory in Aplysia to include more complex forms of memory storage in genetically modified mice. These studies have focused on explicit memory (the conscious recall of information about places and objects), revealing the importance of a balance of activation and inhibition in memory storage so that animals as well as humans do not store information in their memories that is not important to recall.
Eric Kandel: Leonardo, for one, spent a fair amount of time dissecting human cadavers because he wanted to know how the various bones related to one each other and how the muscles related to the bones. So he wanted to have a realistic understanding of the human anatomy because he was depicting real live people sitting, gesturing, walking, and he wanted to get this as absolutely correct as possible.
In order to understand how the body functions, we need to know something about the anatomy of the body, it’s sort of obvious.The more we want to depict the mind, the more it helps to understand the mind, and one way to understand the mind is to understanding the brain. So it is conceivable that as we get deeper and deeper insights into the mind, artists will get ideas about how combinations of stimuli affect, for example, emotional states that will allow them to depict those emotional states better.
But in addition, we’re beginning to get in very, very primitive terms, some insights into the nature of creativity. Hughling Jackson, the great neurologist in the 19th century, thought that the left hemisphere is involved in language. We know this is true. And the left hemisphere is primarily involved in logical processes, calculation, mathematics, rational thinking. The right hemisphere, he thought, is more involved with musicality, which is true. The sing-song in my language comes from the right hemisphere, the grammar and the articulation comes from my left hemisphere. Okay? So he thought that the right hemisphere is more involved in musicality in, you know, synthesis, putting things together and an aspect of creativity. And he felt that the two hemispheres inhibit one another. So if you have lesions of the left hemisphere, that removes the inhibitory constraint on the right hemisphere and frees up certain processes. And he found that certain kids that develop later in life, let’s say, later in their teens, aphasia, a language difficulty; it freed up in them a musicality which they didn’t have before.
People have returned to that more recently in the analysis of a dementia called Frontotemporal Dementia. Frontotemporal Dementia is a dementia somewhat similar to Alzheimer’s disease, it actually begins earlier, that primarily affects the temporal lobe of the brain and the front lobe of the brain. If it’s only expressed on the left side, people with Frontotemporal Dementia begin to show creativity that they’ve never shown before. So if you were painting before, you might start, if you develop Frontotemporal Dementia on the left side, to use colors that you’ve never used before to try forms that you’ve never used before. If you never painted before, you might take up painting for the first time. So this is really quite unusual.
There are also a group of people who have studied aspects of creativity. I can give you a problem that can be solved in one of two ways, systematically working your way through it or putting it together, take a guess, an Aha Phenomenon. And they found that when people do it in a sort of creative way, the Aha Phenomenon, there is a particular area in the right side of the brain that lights up. And they show this not only with imaging, but also with electrophysiological recording.
So this is really quite interesting. You have a number of sort of indirect, not the most compelling evidence in the world, the Aha Phenomenon is well-documented, but it’s only a component of creativity. Number of suggestions, there are aspects of the right hemisphere that might be involved in creativity. But look, as we have been saying all along, we are at a very early stage in understanding higher mental processes, so it’s amazing we know anything about creativity, but this is certainly – we are heading into an era in which one can really get very, very good insights into it and the kinds of situations that lead to increased creativity... you know, is group think productive? Does it lead to great – greater creativity or does it inhibit individual creativity? Lots of these questions are being explored, both from a social psychological and from a biological point of view.

- Push Past Negative Self-Talk: Give Yourself the Proper Fuel to Attack the World, with David Goggins, Former NAVY SealIf you've ever spent 5 minutes trying to meditate, you know something most people don't realize: that our minds are filled, much of the time, with negative nonsense. Messaging from TV, from the news, from advertising, and from difficult daily interactions pulls us mentally in every direction, insisting that we focus on or worry about this or that. To start from a place of strength and stability, you need to quiet your mind and gain control. For former NAVY Seal David Goggins, this begins with recognizing all the negative self-messaging and committing to quieting the mind. It continues with replacing the negative thoughts with positive ones.
Is this proof of a dramatic shift?

Dramatic and misleading

The situation today: CNN pushed back to the edges of the country.
Over the course of no more than a decade, America has radically switched favorites when it comes to cable news networks. As this sequence of maps showing TMAs (Television Market Areas) suggests, CNN is out, Fox News is in.
The maps are certainly dramatic, but also a bit misleading. They nevertheless provide some insight into the state of journalism and the public's attitudes toward the press in the US.
Let's zoom in:
- It's 2008, on the eve of the Obama Era. CNN (blue) dominates the cable news landscape across America. Fox News (red) is an upstart (°1996) with a few regional bastions in the South.
- By 2010, Fox News has broken out of its southern heartland, colonizing markets in the Midwest and the Northwest — and even northern Maine and southern Alaska.
- Two years later, Fox News has lost those two outliers, but has filled up in the middle: it now boasts two large, contiguous blocks in the southeast and northwest, almost touching.
- In 2014, Fox News seems past its prime. The northwestern block has shrunk, the southeastern one has fragmented.
- Energised by Trump's 2016 presidential campaign, Fox News is back with a vengeance. Not only have Maine and Alaska gone from entirely blue to entirely red, so has most of the rest of the U.S. Fox News has plugged the Nebraska Gap: it's no longer possible to walk from coast to coast across CNN territory.
- By 2018, the fortunes from a decade earlier have almost reversed. Fox News rules the roost. CNN clings on to the Pacific Coast, New Mexico, Minnesota and parts of the Northeast — plus a smattering of metropolitan areas in the South and Midwest.

This sequence of maps, showing America turning from blue to red, elicited strong reactions on the Reddit forum where it was published last week. For some, the takeover by Fox News illustrates the demise of all that's good and fair about news journalism. Among the comments?
- "The end is near."
- "The idiocracy grows."
- "(It's) like a spreading disease."
- "One of the more frightening maps I've seen."
- "LOL that's what happens when you're fake news!"
- "CNN went down the toilet on quality."
- "A Minecraft YouTuber could beat CNN's numbers."
- "CNN has become more like a high-school production of a news show."
Not a few find fault with both channels, even if not always to the same degree:
- "That anybody considers either of those networks good news sources is troubling."
- "Both leave you understanding less rather than more."
- "This is what happens when you spout bullsh-- for two years straight. People find an alternative — even if it's just different bullsh--."
- "CNN is sh-- but it's nowhere close to the outright bullsh-- and baseless propaganda Fox News spews."
"Old people learning to Google"

CNN vs. Fox News search terms (200!-2018)
But what do the maps actually show? Created by SICResearch, they do show a huge evolution, but not of both cable news networks' audience size (i.e. Nielsen ratings). The dramatic shift is one in Google search trends. In other words, it shows how often people type in "CNN" or "Fox News" when surfing the web. And that does not necessarily reflect the relative popularity of both networks. As some commenters suggest:
- "I can't remember the last time that I've searched for a news channel on Google. Is it really that difficult for people to type 'cnn.com'?"
- "More than anything else, these maps show smart phone proliferation (among older people) more than anything else."
- "This is a map of how old people and rural areas have learned to use Google in the last decade."
- "This is basically a map of people who don't understand how the internet works, and it's no surprise that it leans conservative."
A visual image as strong as this map sequence looks designed to elicit a vehement response — and its lack of context offers viewers little new information to challenge their preconceptions. Like the news itself, cartography pretends to be objective, but always has an agenda of its own, even if just by the selection of its topics.
The trick is not to despair of maps (or news) but to get a good sense of the parameters that are in play. And, as is often the case (with both maps and news), what's left out is at least as significant as what's actually shown.
One important point: while Fox News is the sole major purveyor of news and opinion with a conservative/right-wing slant, CNN has more competition in the center/left part of the spectrum, notably from MSNBC.
Another: the average age of cable news viewers — whether they watch CNN or Fox News — is in the mid-60s. As a result of a shift in generational habits, TV viewing is down across the board. Younger people are more comfortable with a "cafeteria" approach to their news menu, selecting alternative and online sources for their information.
It should also be noted, however, that Fox News, according to Harvard's Nieman Lab, dominates Facebook when it comes to engagement among news outlets.
CNN, Fox and MSNBC

For the record, here are the Nielsen ratings for average daily viewer total for the three main cable news networks, for 2018 (compared to 2017):
- Fox News: 1,425,000 (-5%)
- MSNBC: 994,000 (+12%)
- CNN: 706,000 (-9%)
And according to this recent overview, the top 50 of the most popular websites in the U.S. includes cnn.com in 28th place, and foxnews.com in... 27th place.The top 5, in descending order, consists of google.com, youtube.com, facebook.com, amazon.com and yahoo.com — the latter being the highest-placed website in the News and Media category.
