Ways Your Brain and Feelings Influence Each Other

This learning path has been created for you.
Playlist Description

The human brain is a remarkable bit of hardware. It helps us to interpret the world around us, regulates our bodies, keeps track of our memories, maintains and makes sense of our senses, and much more. One of its most important responsibilities is to drive our emotions, creating and leading a lot of the hormonal and electrical impulses that make us think and feel certain ways.

When you’re upset about something and your mother tells you to snap out of it because it’s all in your head, she’s half right. A lot of your emotions certainly start in your head, but the interaction between our brains and our feelings is a great deal more complex than simple cause and effect. In some ways, they’re partners in crime, working together to make us feel like we’re capable of anything. In other instances, their relationship can potentially be problematic. Check out this playlist to discover how your brain and your feelings deeply influence one another.

  • About This Video
Your brain gets information from two different sources: Your senses tell you what's going on in the outside world, while your emotions exist inside your body to tell you what these events and circumstances mean to you. Just as hunger motivates you to find food, emotions motivate you to take care of other needs—like safety and companionship—that ultimately promote survival and reproduction. The exhibition, Brain: The Inside Story, which is on view at the American Museum of Natural History from Saturday, November 20, until August 14, 2011, brings visitors up to date on the latest in neuroscience, highlighting the brain's surprising ability to rewire itself in response to experience, disability, or trauma, and showcases new technologies that researchers use to study the brain and treat conditions such as Alzheimer's and Parkinson's.

Oxytocin (aka the Love Hormone) is supposed to make you feel all warm and cuddly. But according to new research, it's also to blame for much deeper and darker feelings. Laci explains this two-faced beast. Read More: The Love Hormone is Two-Faced http://www.northwestern.edu/newscenter/stories/2013/07/the-love-hormone-is-two-faced.html "It turns out the love hormone oxytocin is two-faced. Oxytocin has long been known as the warm, fuzzy hormone that promotes feelings of love, social bonding and well-being. It's even being tested as an anti-anxiety drug. But new Northwestern Medicine® research shows oxytocin also can cause emotional pain, an entirely new, darker identity for the hormone."

Pain is.. a pain. Too much of it, and it can really make life hard. But imagine none of it. That can be bad too, as you'd never know if you're hurt. That's the reality for a select few who carry a rare genetic mutation. Trace explains how our body's pain system works, and how these people could help those suffering from chronic pain in the future. Read More: How Pain Works http://science.howstuffworks.com/life/inside-the-mind/human-brain/pain.htm "What happens when you're cutting a bagel and slice your hand with the knife? Besides all the blood, you'll probably feel an immediate sharp pain, followed by a longer-lasting dull ache." Scorpion-Eating Mice Feel No Sting http://news.discovery.com/animals/scorpion-eating-mice-feel-no-sting-131024.htm "The sting of the Arizona bark scorpion is so fierce that humans say the pain is like being hit by a hammer. But the tiny grasshopper mouse shakes off the sting like it's nothing." Rodent immune to scorpion venom http://www.nature.com/news/rodent-immune-to-scorpion-venom-1.14014 "When the grasshopper mouse attacks a bark scorpion, it barely notices the arachnid's intensely painful sting. Now researchers know why: the rodents have a mutation in the cellular pathway that controls their pain response, making them resistant to scorpion venom." Black mamba venom is 'better painkiller' than morphine http://www.bbc.co.uk/news/health-19812064 "A painkiller as powerful as morphine, but without most of the side-effects, has been found in the deadly venom of the black mamba, say French scientists."
