Summary: A new study reveals a diverse array of genetic changes that occur in the brain following sensory experiences.
“Nature and nurture is a convenient jingle of words, for it separates under two distinct heads the innumerable elements of which personality is composed. Nature is all that a man brings with himself into the world; nurture is every influence from without that affects him after his birth.” – Francis Galton, cousin of Charles Darwin, 1874.
Is it nature or nurture that ultimately shapes a human? Are actions and behaviors a result of genes or environment? Variations of these questions have been explored by countless philosophers and scientists across millennia. Yet, as biologists continue to better understand the mechanisms that underlie brain function, it is increasingly apparent that this long-debated dichotomy may be no dichotomy at all.
In a study published in Nature Neuroscience on Jan. 21, neuroscientists and systems biologists from Harvard Medical School reveal just how inexorably interwoven nature and nurture are in the mouse brain. Using novel technologies developed at HMS, the team looked at how a single sensory experience affects gene expression in the brain by analyzing more than 114,000 individual cells in the mouse visual cortex before and after exposure to light.
Their findings revealed a dramatic and diverse landscape of gene expression changes across all cell types, involving 611 different genes, many linked to neural connectivity and the brain’s ability to rewire itself to learn and adapt.
The results offer insights into how bursts of neuronal activity that last only milliseconds trigger lasting changes in the brain, and open new fields of exploration for efforts to understand how the brain works.
“What we found is, in a sense, amazing. In response to visual stimulation, virtually every cell in the visual cortex is responding in a different way,” said co-senior author Michael Greenberg, the Nathan Marsh Pusey Professor of Neurobiology and chair of the Department of Neurobiology at HMS.
“This in essence addresses the long-asked question about nature and nurture: Is it genes or environment? It’s both, and this is how they come together,” he said.
One out of many
Neuroscientists have known that stimuli–sensory experiences such as touch or sound, metabolic changes, injury and other environmental experiences–can trigger the activation of genetic programs within the brain.
Composed of a vast array of different cells, the brain depends on a complex orchestra of cellular functions to carry out its tasks. Scientists have long sought to understand how individual cells respond to various stimuli. However, due to technological limitations, previous genetic studies largely focused on mixed populations of cells, obscuring critical nuances in cellular behavior.
To build a more comprehensive picture, Greenberg teamed with co-corresponding author Bernardo Sabatini, the Alice and Rodman W. Moorhead III Professor of Neurobiology at HMS, and Allon Klein, assistant professor of systems biology at HMS.
Spearheaded by co-lead authors Sinisa Hrvatin, a postdoctoral fellow in the Greenberg lab, Daniel Hochbaum, a postdoctoral fellow in the Sabatini lab and M. Aurel Nagy, an MD-PhD student in the Greenberg lab, the researchers first housed mice in complete darkness to quiet the visual cortex, the area of the brain that controls vision.
They then exposed the mice to light and studied how it affected genes within the brain. Using technology developed by the Klein lab known as inDrops, they tracked which genes got turned on or off in tens of thousands of individual cells before and after light exposure.
The team found significant changes in gene expression after light exposure in all cell types in the visual cortex–both neurons and, unexpectedly, nonneuronal cells such as astrocytes, macrophages and muscle cells that line blood vessels in the brain.
Roughly 50 to 70 percent of excitatory neurons, for example, exhibited changes regardless of their location or function. Remarkably, the authors said, a large proportion of non-neuronal cells–almost half of all astrocytes, for example–also exhibited changes.
The team identified thousands of genes with altered expression patterns after light exposure, and 611 genes that had at least two-fold increases or decreases.
Many of these genes have been previously linked to structural remodeling in the brain, suggesting that virtually the entire visual cortex, including the vasculature and muscle cell types, may undergo genetically controlled rewiring in response to a sensory experience.
There has been some controversy among neuroscientists over whether gene expression could functionally control plasticity or connectivity between neurons.
“I think our study strongly suggests that this is the case, and that each cell has a unique genetic program that’s tailored to the function of a given cell within a neural circuit,” Greenberg said.
These findings open a wide range of avenues for further study, the authors said. For example, how genetic programs affect the function of specific cell types, how they vary early or later in life and how dysfunction in these programs might contribute to disease, all of which could help scientists learn more about the fundamental workings of the brain.
“Experience and environmental stimuli appear to almost constantly affect gene expression and function throughout the brain. This may help us to understand how processes such as learning and memory formation, which require long-term changes in the brain, arise from the short bursts of electrical activity through which neurons signal to each other,” Greenberg said.
One especially interesting area of inquiry, according to Greenberg, includes the regulatory elements that control the expression of genes in response to sensory experience. In a paper published earlier this year in Molecular Cell, he and his team explored the activity of the FOS/JUN protein complex, which is expressed across many different cell types in the brain but appears to regulate unique programs in each different cell type.
Identifying the regulatory elements that control gene expression is critical because they may account for differences in brain function from one human to another, and may also underlie disorders such as autism, schizophrenia and bipolar disease, the researchers said.
“We’re sitting on a goldmine of questions that can help us better understand how the brain works,” Greenberg said. “And there is a whole field of exploration waiting to be tapped.”

Single-cell analysis of experience-dependent transcriptomic states in the mouse visual cortex
Activity-dependent transcriptional responses shape cortical function. However, a comprehensive understanding of the diversity of these responses across the full range of cortical cell types, and how these changes contribute to neuronal plasticity and disease, is lacking. To investigate the breadth of transcriptional changes that occur across cell types in the mouse visual cortex after exposure to light, we applied high-throughput single-cell RNA sequencing. We identified significant and divergent transcriptional responses to stimulation in each of the 30 cell types characterized, thus revealing 611 stimulus-responsive genes. Excitatory pyramidal neurons exhibited inter- and intralaminar heterogeneity in the induction of stimulus-responsive genes. Non-neuronal cells showed clear transcriptional responses that may regulate experience-dependent changes in neurovascular coupling and myelination. Together, these results reveal the dynamic landscape of the stimulus-dependent transcriptional changes occurring across cell types in the visual cortex; these changes are probably critical for cortical function and may be sites of deregulation in developmental brain disorders.

Biologist Janine Benyus likes to tell stories about using nature to solve our problems. For instance, a company called Arnold Glas was concerned about all the birds killed when they fly into windows. The company’s scientists asked, How has nature solved this kind of problem? The answer, Benyus says, is spiders. “Spiders build webs for bugs,” she explains. “But birds obviously would destroy the webs, so spiders weave in strands of silk that reflect UV light. Birds can see it, but bugs and humans can’t.” So the company includes UV-reflective material in its Ornilux glass. “Now it sells bird-safe windows,” says Benyus.
With that, she illustrates the big idea behind “biomimicry” (the term she coined in 1997): that humans can borrow the best ideas from the natural world. Her consulting firm, Biomimicry 3.8, works with major corporations, like Nike, GE, and Boeing, as they look to the earth to create smarter products and services.
You’ve said, “If something can’t be found in nature, there’s probably a good reason for its absence.” Can you explain this?
Ninety-nine percent of all species that existed on earth are extinct. The 1 percent here are the ones that work best. Think of our planet as a research-and-development lab in which the best ideas have moved forward, and the ones that used too much energy or materials or were toxic were dropped. What you wind up with are organisms that are efficient.
Do those organisms include humans?
No. Humans have been around for only 200,000 years, as opposed to the 3.8 billion years that life has existed on earth. I see us as toddlers with matches. We’re experimental; we try a lot of things because we can. But at this point, we have to ask ourselves as a species: Do we want to be here 1,000 generations from now? If so, we need to choose things that are good for life. I think we can invent things that don’t have negative consequences. Other people are more pessimistic than I am; I’m optimistic by choice because I believe that pessimism doesn’t do a whole heck of a lot of good. I work with large companies, and they’re all trying to figure out how to do what they do and make profits without penalties and harmful consequences.
What’s an example of how businesses are using biomimicry?
Continental Tires uses a tread that enables drivers to stop on a dime. It comes from cat paws.
The company uses actual cat paws to make them?!
No, but good question. In biomimicry, we borrow the blueprints and ideas rather than use nature itself. One cool example is a new paint that helps a building clean itself with rainwater. The product is called Lotusan, as in lotus leaves. Even though lotuses grow in the mud, they stay pristine. Scientists found that microscopic bumps on the leaves cause rain to form balls like beads of mercury. As these balls of water roll off the leaves, they pick up the dirt. GE is making bottles based on the leaves so that if you have ketchup or mustard in them, you can pour out every single drop.
What one plant or animal do you consider the star, the one that we can learn from the most?
Mycorrhizal fungus. It’s everywhere, and without it, we couldn’t exist. If you look at the roots of plants and trees, you’ll often see this white cobwebby stuff. This fungus works in partnership with plants and trees. It can’t get sunlight, since it’s underground, but trees can, and they use the sun to produce sugars, which they send down to the fungi. Trees can’t get phosphorous, but the fungi can, so they give it to the trees. In forests, this fungus creates an interconnected network—the Wood Wide Web, it’s been called—and trees and plants can share nutrients, sugars, and water with others a half acre away.
How would an ordinary person use biomimicry?
I’ll give you an example. I wanted to plant willow trees around my pond in Montana, and I wondered, How far back from the water’s edge should they go? I went online for the answer, and then I realized, I’m surrounded by ponds. Why don’t I look at where the willows are doing well and see where I should plant mine?
I would’ve Googled it too.
But isn’t that crazy? The thing with biomimicry is to think functionally. When I built my house, I looked at how the ground squirrels on my property ventilated their dens. They build these long underground chambers. There’s a mound with an entrance on one end and a taller mound with an entrance at the other end. The wind zips through the taller mound, creating a vacuum that pulls air through the chambers, ventilating them. I told our architect I wanted to do this, and he put a cupola with windows at the top of the house. When I open the doors, the breezes go through the cupola and suck the air through the house, ventilating it.
What’s your holy grail?
I’d like us to become a species that not only fits in but contributes. Forests clean the water for cities, but whom do cities clean the water for? Nobody. No species gets to live here for long without figuring out how to create conditions conducive to the life of the whole ecosystem. And it’s doable. The Bank of America building in New York has a filtration system that leaves the air cleaner than when it enters. Cities could build permeable sidewalks so rainwater would seep into the pavement and into the soil, cleaning it. It’s about mimicking the wild land next door. The cool thing about nature’s technologies is that they don’t come from outer space. They’re here because they work well on earth.
Is there one ability you’d personally like to borrow from the natural world?
I’d love to run off the mountains, spread my wings, and fly. And you know what else I wish I could do? Swim deep underwater without a tank and just take air out of the water like a fish. I’d love that: to fly in the air and to fly in the water!
What would you say to a skeptic who asks, “What’s so great about nature anyway?”
Ask your payroll if you can split your income to W2 (base) and 1099 (extra) to allow your 1099 income into a C corp for max savings and min income taxes.
Working for a hospital allowing you to do a 1099 can save you more in income taxes and increase your savings.
With VA doctors, payroll will not let you split your income but do ask them anyway.
Combination of W2 and 1099, allows you to have more healthcare deductible benefits.
Use your corporation to write off more of your expenses.
We can work with your payroll dept and CPA to allow you to save more and min income taxes. Contact Connie Dello Buono, financial planner for doctors , 408-854-1883 email@example.com
