But exactly _why_ we scream has remained a mystery. Now, new [research](http://dx.doi.org/10.1016/j.cub.2015.06.043) published in the journal _Current Biology_ suggests that hearing a scream may activate the brain’s fear circuitry, acting as a cautionary signal. Scream science is a new area of study, so David Poeppel, a professor of psychology and neural science at New York University, and his co-authors collected an array of screams from YouTube, films and 19 volunteer screamers who screamed in a lab sound booth. (This last collection method, by the way, was a highlight for Poeppel, who said he found listening to and judging screams an amusing break from the monotony of lab work.) The researchers first measured the sound properties of screams versus normal conversation. They measured the scream’s volume and looked at how volunteers responded behaviorally to screams. They then looked at brain images of people listening to screams and saw something they found fascinating—screams weren’t being interpreted by the brain the way normal sounds were. Normally, your brain takes a sound you hear and delivers it to a section of your brain dedicated to making sense of these sounds: What is the gender of the speaker? Their age? Their tone? Screams, however, don’t seem to follow that route. Instead, the team discovered that screams are sent from the ear to the amygdala, the brain’s fear processing warehouse, says Poeppel. “In brain imaging parts of the experiment, screams activate the fear circuitry of the brain,” he says. “The amygdala is a nucleus in the brain especially sensitive to information about fear.” That means screams are inherently considered not just sound but a trigger for heightened awareness. From these screams, Poeppel and his team mapped “roughness,” an acoustic description for how fast a sound changes in loudness. While normal speech modulates between 4 and 5 Hz in sound variation, screams spike between 30 and 150 Hz. The higher the sound variation, the more terrifying the scream is perceived. Poeppel and his team had volunteers listen to different alarm sounds and found people responded to alarms with similar variations: The more the alarms varied at higher rates, the more terrifying they were judged to be. That huge variation in scream roughness is a clue to how our brains process danger sounds, Poeppel says. Screaming serves not only to convey danger but also to induce fear in the listener and heighten awareness for both screamer and listener to respond to their environment. ## Transcript [00:05] [ MUSIC ] $ 1, 000 can really put you on the road to [00:07] good health, or at least to better health. A lot of [00:11] workers say that they're really stressed, unless [00:13] productive. But half of workers say that stress makes [00:17] them less productive at work. And there are a lot of [00:20] studies that show that people who are more stressed [00:23] have higher medical bills. And that makes sense. If you [00:26] are stressed you may miss more work. You may go, go [00:28] to doctor more often. So if you can invest $ 1000, you [00:31] can really improve your health and lower your own [00:34] costs. Yoga is a great way to reduce stress. It helps [00:37] you with deep breathing, relaxation exercises. And a [00:40] mindfulness that can really reduce your tension. Yoga [00:44] classes cost about $ 15 to $ 20 each, at, that would [00:47] get you doing downward dog about twice a week for [00:50] six months. Acupuncture is another great way to [00:53] reduce stress. It may be covered by your health [00:55] insurance, so check that first. If not, acupuncture [00:58] sessions cost about $ 16 to $ 120. Modern exercise [01:03] has been proven as a great way to reduce stress. To [01:06] incorporate it on a regular basis in your busy life, [01:10] consider riding your bike to and from work. Or, taking [01:14] a bike ride when you get home from work in the [01:15] evening. Now, a good bike can cost you $ 1000. But [01:19] think of it as a long- term investment, a good bike will [01:22] last you many. If you have 10 thousand dollars, there's [01:25] a lot you can do to invest in your health. A personal [01:28] trainer, may give you the motivation you need to [01:31] exercise, that you might not be able to do on your [01:33] own. That costs you about 50 dollars a session, which [01:37] could give you about 100 sessions, that you could [01:40] spread out over two years. Another great way to. T [01:43] find someone to motivate you is to consult a [01:45] nutritionist. A first- time session with a nutitionist will [01:47] cost about $ 150. But, if you wanna do follow- up [01:51] sessions, to create say a health plan to see how you're [01:54] doing, that'll cost you about $ 100. See if your health [01:57] insurance may cover that, as well.
