Episode 1: Neuroscience of Anxiety

Whether it's meeting your ex at a party or your upcoming presentation at work, we have all felt the sinking feeling of anxiety. Come and find out a little bit about what's happening upstairs in this bite-sized look at the brain regions, connections, and neurotransmitters involved in anxiety processing and regulation.
