Stress And The Brain: JaimeTartar at TEDxNSU

Jaime Tartar tells us about how the brain interprets what is stressful, how it determines our behavioral and physiological response to stressors, and how it can be damaged by stress. She will discuss how the body’s reaction to acute stress has protective and adaptive effects in the short run while chronic stress can lead to poor health consequences such as decreased memory performance and depression. Tartar is an Associate Professor of Psychology at Nova Southeastern University.In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

Does stress affect your memory? – Elizabeth Cox

Explore the stages of how your memory stores information and how short-term stress impacts this process.—You spend weeks studying for an important test. On the big day, you wait nervously as your teacher hands it out. You’re working your way through, when you’re asked to define “ataraxia.” You know you’ve seen the word before, but your mind goes blank. What just happened? Elizabeth Cox details the complex relationship between stress and memory.Lesson by Elizabeth Cox, directed by Artrake Studio.Sign up for our newsletter: http://bit.ly/TEDEdNewsletter Support us on Patreon: http://bit.ly/TEDEdPatreon Follow us on Facebook: http://bit.ly/TEDEdFacebook Find us on Twitter: http://bit.ly/TEDEdTwitter Peep us on Instagram: http://bit.ly/TEDEdInstagram View full lesson: https://ed.ted.com/lessons/the-surprising-link-between-stress-and-memory-elizabeth-coxThank you so much to our patrons for your support!

Conquering Exam Stress: Lessons From Our Bodies

We all know how stressful exam time can be. When we let our stress levels get too intense for long periods of time, it can have negative effects on our physical and mental well-being. But stress itself isn’t all bad. If we understand the science of what’s happening in our bodies when we feel stressed, we can learn to keep those feelings balanced and make them work for us. So how do we do that? Watch this video for scientific tips on how to tame your stress and let it do its job – preparing you for the challenge ahead!Credits: Produced by Orinoco Communications Animation: Rosie Holtom Illustration: Alex Scarfe Narration: Ellie Lees Focus group: Olga Markoulides and her students at Newham Sixth Form College Scientific advisors: Sarah Hall, Hans Reul, Francesca Spiga, Phil Rhodes Director: Peter Barker

The Science of Stress: From Psychology to Physiology

What goes on in our bodies and minds to cause stress? Watch the Q&A here: https://youtu.be/UYUiX7SqWn0 Subscribe for regular science videos: http://bit.ly/RiSubscRibeStress is our natural reaction to physical or emotional pressure, encompassing everything from too much work to being tortured. But how does stress affect our memory, mood and thinking? And what effect does stress have on our overall health? Vincent Walsh and a panel of experts investigate.Vincent Walsh is a neuroscientist at University College London interested in finding out how the brain works. He is particularly fascinated by the the things we take for granted, like dealing with stressful situations.Joe Herbert is interested in the role of the brain in adaptive responses, with particular reference to the reciprocal interaction between hormones and the brain. He is a Professor at the Department of Clinical Neurosciences at the University of Cambridge.Shane O’Mara is Professor of Experimental Brain Research in Trinity College Dublin. His research focuses on the relations between cognition, synaptic plasticity and behaviour, in the context of brain aging and depression.Julie Turner-Cobb is Professor of Psychology at Bournemouth University. She researches the effects of psychosocial factors, particularly stress, coping and social support, on endocrine functioning across a range of acute and chronic health conditions in adults and children.The Ri is on Twitter: http://twitter.com/ri_science and Facebook: http://www.facebook.com/royalinstitution and Tumblr: http://ri-science.tumblr.com/ Our editorial policy: http://www.rigb.org/home/editorial-policy Subscribe for the latest science videos: http://bit.ly/RiNewsletter
