Understanding how bi-lateral stimulation can reduce distress, shift stuck memories and aid in prevention of PTSD ✨
How does EMDR work?
When we experience something overwhelming, there is reduced control of the pre-frontal cortex over the activated amygdala and hippocampus (these both become overstimulated). In other words, when you are triggered, the rational thinking part of your brain can’t control the emotional part of the brain.
Some memories get ‘stuck’ in the amygdala-hippocampal cortex and when triggered, they seem to occur in the present. ‘Stuck’ memories are thought to be unprocessed memories.
Neuroscientists propose that what happens during REM (dream) sleep happens during EMDR.
During MyEMDR, we move your eyes from side to side whilst getting you to focus on a fragmented memory/experience or emotion. Much like when your eyes move side to side when you dream.
This side-to-side motion (also referred to as bilateral stimulation) elicits a synchronisation of all cortical activity at a frequency in the delta range like slow-wave sleep. EMDR temporarily slows your over-stimulated amygdala down and synchronises your brain waves helping you to process the memory/ experience and reduce activation along with level of distress.
