The Neuroscience of Fear Conditioning
Fear conditioning is a psychological experiment that teaches the brain to fear a certain stimulus and physical environment. The neuroscience of fear conditioning helps explain how our brains learn to fear particular things and experiences. In the brain, it mainly involves the hippocampus, frontal lobes, and amygdala. This understanding is leading neuroscientists to discover new therapeutic approaches for anxiety disorders.
This video explores fear conditioning (and a related process called “fear extinction”), including how it works, the neural circuits responsible, and how this understanding is helping psychiatrists to treat anxiety.

Fear Extinction.... my new mission TY🙏
This is very useful information, thanks for sharing
The weather triggers me to have debilitating pain/fatigue symptoms and I believe it’s a conditioned response but I don’t know how to extinguish it. I’m not consciously afraid of any weather and love rain.
Well done. Thank you

Love this video! are you on audea? Most of my audio is consumed there and would appreciate the audio version of your content on that platform.

I’m not yet, but thank you for the suggestion! I’ll certainly look into it and see what I can do. We are on all major podcast platforms though!
So informative! There's a lot of unconscious processes with fear. It would be cool if you did a video of the neuroscience of EMDR or clinical hypnosis treatment, but I'm biased 🤓

Thank you so much Liz! Those both sound super interesting! I'll have to read up 📖

That's exactly what I was thinking! Because those procedures seem to somehow dissociate stimuli from their emotional significance and that's not clearly understood

Sir, How do i avoid or reduce fear renewal ? Suppose i learned to process th fear extinction but what about this fear renewal
How can this be applied regarding how fear, abuse, etc triggers the Vegus nerve whereby starting a negative or positive chain reaction of organ response activation?
@senseofmindshow

Thanks for your question! Any thought or experience that triggers the fight or flight response (which is what I assume you mean by "chain reaction of organ response activation") will do so by activating the amygdala. Some of the therapeutic approaches I mentioned at the end of the video might be helpful for reducing that amygdala response, but that is something you should discuss with a mental health professional before trying it. Also, I have a video on the amygdala that might be of interest to you on this topic: kzread.info/dash/bejne/mIypvNKGmbateM4.html
