Who’s afraid of the amygdala?


The amygdala is a little clump of cells in your brain that’s often passed off as the place where your deepest fears are born.

But, in reality, the amygdala has less to do with things that go bump in the night, and more to do with your ability to pay attention to the world around you and learn what’s safe and what’s not.

Here’s a really fascinating excerpt from my BoingBoing interview with neuroscientist Paul Whalen, all about what happens to people who don’t have a working amygdala.

MKB: So, the amygdala is actually about how we pay attention to anything — not just stuff that makes us anxious or afraid — but anything?

PW: At the end of the day, it’s an attentional area of the brain. It tells us to be more vigilant, to be more aware of our surroundings right now. With that signal from the amygdala, your visual system or auditory system might see something or hear something that it would have missed otherwise. The amygdala sends the initial signal that tells the other parts of the brain to be better at what they do.

Here’s a human example. S.M. is a patient with bilateral amygdala lesions. She can be afraid. But she’s bad at learning about the things that cause fear. We show people these very exaggerated pictures of faces, some fearful, some not, and people give us a number for how afraid they should be. S.M, she’ll say something is a “2” on faces that other people say is a “5”. If I were to show you a fearful face, you’d look straight at the eyes. That’s where we get a lot of our information. But S.M. doesn’t. She stays focused on the middle of the face, or even goes to the mouth and chin. Her attention doesn’t go to the place where she should know you learn best. Now, if you tell her to look at the eyes, her ratings are normal. The amygdala wasn’t her source of the ability to be afraid. It was the source of her ability to know where to look to learn whether she should be afraid. The amygdala just facilitates that. It makes you better at learning what signals to pay attention to.

Eureka: The intersection between science and culture

Last weekend, I started a new job, writing a monthly column on science and culture for The New York Times Magazine. The column is called Eureka. In the first edition, I look at “flip-flopping” politicians and examine what factors actually make people likely to change their minds on deeply held beliefs.

Hint: It’s not data and evidence.

Scientists have been studying attitudes and preferences for more than a century; those topics are bound to the origins of social psychology itself. Some of the earliest research, like William Thomas and Florian Znaniecki’s five-volume set, “The Polish Peasant in Europe and America,” published in 1918, revolved around the attitudes of immigrants: how they lived, what their neighbors thought of them, how they changed as they became Americans.

In the last decade, psychologists have focused increasing attention on moral attitudes. Jonathan Haidt, professor of psychology at the Stern School of Business at New York University and author of “The Righteous Mind,” told me that researchers have been especially interested in the way emotions and attitudes interact. Moral attitudes are especially difficult to change, Haidt said, because the emotions attached to those preferences largely define who we are. “Certain beliefs are so important for a society or group that they become part of how you prove your identity,” he said. “It’s as though we circle around these ideas. It’s how we become one.”

Upcoming events in Kansas City and Lawrence

I’m going to be speaking in Lawrence, Kansas, and Kansas City in about a week.

Both events are centered on Before the Lights Go Out, my book about electricity, infrastructure, and the future of energy.  Before the Lights Go Out is about some of the big-picture nuance that gets left out of the day-to-day chatter about energy. What are the big trends that will shape what we can and can’t do over the next 40 years? How does our electricity infrastructure work, and why is that infrastructure a lot more interesting (and a lot more complicated) than most laypeople realize? There’s a lot of storytelling, and some fun and funny history of how our current infrastructure came to be. There’s critical analysis explaining both why we have to solve our energy problem, and why solving it is going to be harder than many climate hawks want to believe. In general, the book is meant to make a confusing subject accessible and offer a more nuanced perspective on a topic that tends to be very ideology driven.

Thursday, August 30, 7:00 pm — The Raven bookstore in Lawrence

I’ll be back in my college town to talk about the weird, messy history of electricity, and the ways that writing online can help build a better book. Join me at 6 East 7th Street, Lawrence, Kansas.

Friday, August 31, 7:00 pm — Prospero’s Books in Kansas City

My event at Prospero’s will cover a lot of the same ground as The Raven event, but will get more in-depth on the engineering of how our electric grid works and why this flawed system affects what we can and can’t do to solve our energy problems. RSVP for the Prospero’s event (and get address info) on Facebook!

Blackouts in India: What’s it mean for us?

I’m currently putting together a BoingBoing post about the problems with the American grid and efforts to solve them. Two things you should know about the India blackouts, though.

1) You can’t really make a 1-to-1 comparison between grid problems in India and grid problems in the U.S. We both have problems, but also have different grids and different issues affecting those grids. My understanding from researching Before the Lights Go Out, my book about electricity infrastructure in the U.S., is that we aren’t currently in danger of imminent massive-scale blackouts like what they’re experiencing in India. That said, if we don’t make updates, we could have big problems in the future.

2) Extreme weather and increasing electric demand will stress and break any grid, anywhere. It happens all the time in the United States. We just have pretty good systems for dealing with it.

More to come! But if you want to know more about how grids work and why they fail, this would be a pretty good time to read Before the Lights Go Out!

Three upcoming events in New York City

I’m going to be in New York May 26 through May 30th and I’ve got three big public events set up during that time.

May 28, 3:00 pm: Join Dean Putney, BoingBoing’s intrepid tech guru, and me for an informal Memorial Day picnic in Prospect Park, Brooklyn. We’ll be meeting out front of the Brooklyn Museum and we’ll be bringing bubbles. You bring your food and any cool projects you’d like to show off to other Happy Mutants.

May 29, 6:00 pm: I’ll be talking to the Science Writers of New York about my book, Before the Lights Go Out, the process of book writing, and the benefits of working online. The talk will be at the CUNY Graduate School of Journalism, 219 West 40th Street, in room 330. It’s free and open to the public, but you do need to RSVP. If you want to buy a copy of Before the Lights Go Out, I’ll have some on hand to sell and sign. They’re $24 and I can accept cash or check.

May 30, 6:30 pm: I’ll be leading a panel on decentralized/distributed electricity generation. From DIY home power projects, to the benefits (and problems) of fitting smaller scale power into the grid, this panel will look at what happens when we start making electricity on a smaller scale. Joining me are Chris Hackett—host of the Science Channel’s Stuck with Hackett—and Susan Covino of PJM Interconnect, one of the independent organizations that controls movement of electricity around the grid. Again, this is something you should RSVP for.  It’ll be at 199 Lafayette Street, Third Floor, in Manhattan. If you want to buy a copy of Before the Lights Go Out, I’ll have some on hand to sell and sign. They’re $24 and I can accept cash or check.

Hope to see you at these events!

Book launch party for Before the Lights Go Out – April 19th in Minneapolis

Please join me April 19th, 6:30 pm, at the Bakken Museum to     celebrate the publication of Before the Lights Go Out, my new book about the future of energy in the United States.

I’ll be giving a talk about our energy past, present, and future. There will also be a book signing, snacks, and an opportunity to experience electricity first-hand with the help of the Bakken’s shocking Leyden jar.  If you’re not familiar with the Bakken, it’s a whole museum dedicated to the history and science of electricity. The perfect place to celebrate a book about the electric grid. 

The party is hosted by the Bakken Museum, the Minnesota chapter of the US Green Building Council and the AIA Minnesota Committee on the Environment. The evening is sponsored by the Weidt Group.

The event is free and open to the public. Seating is limited to 70.

Putting the Fun Back in Infrastructure

Electricity just happens. Flip a switch, and the lights turn on. The system is reliable enough and invisible enough that it’s easy to spend your entire life not knowing how it works, even though you use it every day. But in an age of limited resources and environmental change, ignoring our electric infrastructure is a luxury we can no longer afford. The good news: Infrastructure is fascinating. Maggie Koerth-Baker explains how our flawed and surprisingly precarious electric system evolved, how it controls what we can and can’t do to solve our energy crisis today, and what we can learn about the future of energy by studying its past.
