It's difficult for therapists to help these patients, Radulovic said, because the patients themselves can't remember their traumatic experiences that are the root cause of their symptoms.
The best way to access the memories in this system is to return the brain to the same state of consciousness as when the memory was encoded, the study showed.
"The brain functions in different states, much like a radio operates at AM and FM frequency bands," Radulovic said. "It's as if the brain is normally tuned to FM stations to access memories, but needs to be tuned to AM stations to access subconscious memories. If a traumatic event occurs when these extra-synaptic GABA receptors are activated, the memory of this event cannot be accessed unless these receptors are activated once again, essentially tuning the brain into the AM stations."
