Neuroscientist Morten Kringelbach discusses radical new brain imaging technology, and army doctor Alexander Wieck Fjaeldstad describes how smells trigger memories to reveal what is going on inside the brains of people affected by psychological trauma, head injury and PTSD.

Morten Kringelbach’s research goal is to reverse-engineer the human brain and in particular to elucidate the heuristics that allow us to survive and thrive. His focus is on elucidating hedonia (pleasure) and eudaimonia (the life well-lived), and how they are affected in health and disease; in particular, seeking to elucidate their breakdown in anhedonia (the lack of pleasure) in neuropsychiatric disorders.

Alexander Wieck Fjaeldstad is an MD-PhD who served as a Captain in the Danish army. After deployment in Iraq, he became aware of how certain smells can be potent triggers of memories from the battlefield. This link provides a unique window for examining how the brain processes these memories in veterans with and without PTSD. His research focuses on understanding olfaction in the brain and how this can be used clinically.

The fictional character River Tam from Firefly suffers from mental trauma.

Shannon says:

Very good video, thank you!

Long Nguyen says:

so touching for an excellent video

Dwn ramadhana says:

the sound is not good I am quite disappointed

ExiledGypsy says:

Nothing has changed. You are still looked upon as weak. Even psychiatrists tell you some are strong enough to take it but you are not. So, psychologists reveal in talking about it. C-PSDT is the worst.
You end up hoping for neuclear holocaust.

Kassy Wilson says:

I wonder if Dr.s Fjaeldstad and Kringlebach are aware of the research of Drs. Rosenthal and Wilson, on PTSD and why some are afflicted and others are not?

Chris Kokolios says:

I don’t want to talk about my problems the feelings of tremendous anxiety depression and anger that I feel because in the country I live there is a huge stigma on this i would be an outcast of society .I find it inhumane that in some regions there is no empathy for people suffering

Owls eye see it says:

The smell is a very important factor in ptsd.

Ten Minute Tokyo 2 says:

Or working 85 hours a week in Silicon Valley for 30 years only to be run out of your industry + state, and home by invading armies of India Inc staffers.

Dana Shannon says:

Very triggering. Jesus

Dana Shannon says:

They focus so much on soilders.

Dana Shannon says:

PTSD is no joke. Extrenemy challenging beyond words.

BenGun 67 says:

I wrote down the most extreme experiences I personally had to deal with
and how I went through it, the older I get
the more I work on how to handle this on my own ( expecting self-efficacy ).
So far I counted 9 extremely unpleasant emotional situations, – my conclusion is:
The more you take your optimism for granted the easier you get yourself out of the slumb.

Simon Jessop says:

I was involved in a hit n run accident and still healing myself from ptsd and smashing my hip, ribs and I see the car hit me , this was 5 months ago , I've had no help , only told I've got ptsd or concussion after the scan 2 months after the accident. During these hard times of viruses , I'm training my brain myself, I'm trying , but it's real hard , feels like I'm not important not wanted , but my mind in so open to everything ,, I don't know what to do , my emotions are still everywhere x x

Greg Zeng says:

PTSD. It can be minimized. Give the words that might be used to describe the possible experience.
Brain electrolytes are forcibly changed in open heart surgery. Autonomic sensors of many types are sending wrong data to conscious and unconscious parts of the brain. Timings of the brain automata are desynchronized.
The video wrongly describes overclocking the CPU. In my case, desynchronized GPU, GPS and optical illusions (patterns) were regularly & very predictably incurred.
Locked in syndrome (no verbiage to try to understand the experience, plus inability to understand the experience) … led to hyper arousal.
Intensive Care Unit (hospital), with hourly bloody tests, catheters, alarms, lights, no sleep, electrolyte imbalance, … .
Then conscious and unconscious PTSD that this uncontrollable brain trauma can happen again, so unpredictability, do uncontrollably!!
CBT and virtualization (3d visual goggles, with user selected controls, including audio) … might work.
Post surgery needs to protect the traumatized person from nasty visual and aural hallucinations. Eye darkness or nice visuals, and-or ear bud sounds?

Greg Zeng says:

10 months after open heart surgery I experienced anhedonia. Pre existing was 35 years of moderate traumatic brain injury (motor vehicle accident, 1985, Sydney, Australia).
Anhedonia is watching poor quality monochrome tv, compared to full color, full sound 3d tv.
Anhedonia in my case: low dose anti depressants, with cognitive behavioral therapy.

Kristine says:

I had a TBI when I was 16 and now have PTSD, I am on disability and struggle each day. I appreciate you’re video and helping others by talking about the affects of daily life.

Walter Green says:

Lot of wasted time in introduction. Simple statement of purpose of lectures and speakers is all that is necessary.

Anna Lecroix says:

Okay first speaker, r u talking about ptsd or are you talking about your self.

MtnTow says:

You'd be amazed at the levels of PTSD that comes from ghetto life.

Arnon Tillmann says:

In countries where the military is underdeveloped (lacks scientific background), basic military training the main goal is to simulate combat stress. Isn't it enough, if done in a careless way, potentially traumatizing aswell?
