KEY POINTS

We all know that feeling of fear, but what causes it in the brain? A new study looks at how stress can morph into persistent fear responses. Researchers discovered a switch in brain chemicals (neurotransmitters) in mice, which may explain why stressful experiences can sometimes lead to ongoing anxiety. Guest, MHTN Chief Medical Officer Dr. Dan Bober, joins Patricia Wu and Jessica Reyes to discuss this research and what it might mean for treating disorders like PTSD.

The Brain’s Fear Center

Dr. Bober explains the role of the amygdala, the brain’s ‘fear center’, in our survival instincts. He highlights how the fear response sometimes gets stuck in the ‘on’ position, particularly after trauma.

The Science Behind Fear

The study on mice suggests that stressful experiences can cause a shift in neurotransmitters, leading to heightened and lasting fear responses.

Hope for Better Treatments

While research on animals doesn’t always translate directly to humans, this work points to potential targets for new treatments that could help people with PTSD and other anxiety disorders.
