Tremoring in the wild
The following video shows an impala, which has gone into the freeze response. Before it went into freeze, the impala was running for its life, its system flooded with adrenaline, cortisol, and glucose, which empowered it to flee. Luckily for the impala, a hyena distracted the leopard, and then two baboons chased the leopard away.
Thanks to a patient (amateur) videographer, we get to witness the impala coming out of freeze into a natural tremoring response, which releases the fight/flight energy that was aborted by the freeze. In spite of its harrowing experience, the impala bounds off, never to suffer PTSD or other trauma- or stress-related diseases, thanks to the fact that it “shook off” the traumatic experience immediately after it took place.
A short animated explanation of the Impala's experience
This video also explains the freeze mode, which the impala in the video above goes into.
Savannah’s first deer hunt
We show an edited version of this video during our trainings, but if you don’t eat meat, you might want to skip this one. The reason 9-year-old Savannah shakes in this video is because of a phenomenon called “buck fever.” In Savannah’s case, it came after she shot her first buck. What we love is her inquisitive fearlessness about the shaking itself and the fact that her good-natured dad gave her the time to shake until she was done.
Dr. David Berceli on different kinds of tremoring
Dr. Berceli, creator of TRE, addresses how the fields of psychology, neurology, and physiology view different kinds of tremors.
The Neurobiological theory of Tremors
Here is a short explanation of how the tremors work in the body's muscle and nervous systems.
This well-produced eight-minute introduction to TRE was created in New Zealand.
TRE for foster children
DJ (who was adopted as a child) and Lyle Fuller opened their home to foster children and began adopting them in 2007. Because the children had grown up in harsh family environments and the foster system, DJ taught them TRE, which has helped them heal.
The cat and the cucumber
This is the video we use in our trainings to show how lightening-quick our survival instincts are. In seven seconds, it shows all three parts of the stress response cycle: safety, a (perceived) threat, and response.
