Music and memory recall
https://youtu.be/z4PKzz81m5c I found a recent article on research conducted in 2013 which focused on the impact of music and Traumatic Brain Injuries. The research examined music evoking memories that had otherwise been forgotten.
This study had participants who had suffered severe TBIs listening to number-one songs from their lifetimes to see what memories were evoked (Baird & Sampson, 2013).
"The memories brought back were mostly of people or a period of their lives and were broadly similar to those evoked by control participants who did not have a TBI. Compared to using a standardized interview–the Autobiographical Memory Interview–playing number-one hits to people who had suffered Traumatic Brain Injuries was more effective in eliciting memories."
