“Especially in stress, our reptile brain is active, so those affected are not optimally able to reflect” – says an HR manager in an interview with me about stress.

The reptile brain is our oldest part of the brain.

This is where the norepinephrine is formed.

During stress, the hormone norepinephrine is released and ensures the rapid ramp-up of our stress system.

Do you know that the reptile brain connects us to the crocodile: The development of the crocodile brain is a decisive advance in our human evolution, and we humans still benefit from it today.

We inherited “important grey cells” from the crocodiles that still form part of our brainstem today.
