When we listen to music, our moods and minds are influenced in ways we might not notice. Listening to music activates different parts of our brain, which has been shown to positively affect brain development, learning, and functioning (Areas, 2005). Some of these functions include “attention, listening, speech production, emotions, motor skills, memory, coordination, and decision making” (Areas, 2005).
I noticed that I gravitate towards certain music depending on my mood or the time of day. And for the longest time, I struggled with finding the perfect genre of music to listen to when I study or get academic work done.
I found I couldn’t listen to my favorite songs or music because my brain quickly developed a negative association between my favorite songs and whatever I’m doing. For example, I thought listening to my favorite songs could help me get through the work, but when I go back and listen to the songs again weeks or months later, I would be reminded of the time I was stressed and anxious from studying or completing a major project.
So, I experimented with different genres: piano, lofi, classical, meditation, music with nature sounds, video game music, movie/show soundtracks, but they never stuck. One day, I came across hour-long videos on YouTube of binaural beats and ‘bilateral stimulation music’. It turns out this ‘bilateral stimulation music” is used for a therapy method called EMDR (eye-movement desensitization and reprocessing).
Brief Overview of EMDR
EMDR is a therapeutic approach based on the adaptive information processing (AIP) model (Oren & Solomon, 2012). Sometimes thought of as a variant of cognitive-behavioral therapy, EMDR involves an eight-phase approach that helps a person perceptual information (memories) that have been ‘maladaptively stored’ (Shapiro, 2002). Research has found EMDR therapy to be an effective treatment of trauma (Oren & Solomon, 2012). With EMDR therapy, we can process disturbing events, especially ones that we aren’t aware of. Other goals of EMDR includes “facilitates resolution of memories, …, desensitize stimuli that trigger present distress as a result of second-order conditioning, and incorporate adaptive attitudes, skills, and behaviors for enhanced functioning within larger social systems” (Shapiro, 2002).
When we listen to bilateral stimulation, the brain can process negative or traumatic experiences which leads to memory reconsolidation (Oren & Solomon, 2012). Some other methods of EMDR besides bilateral stimulation music (alternating auditory tones) includes side-to-side eye movements and alternating hand taps (Oren & Solomon, 2012).
However, van den Hout and Engelhard (2012) argue that these bilateral stimulation techniques may not be essential for the therapeutic effect. Instead, they suggest that what makes EMDR effective is the taxing of working memory during trauma recall. In other words, van den Hout and Engelhard claim that EMDR works best when we make our brain do two things at once.
What is bilateral stimulation music?
For bilateral music to be effective, listeners should hear the music using headphones. The music alternates between the right and left ear stereo channels. This bilateral music helps a person process stressful or traumatic memories without triggering severe stress (“Bilateral Music fo Anxiety, Stress and Trauma”).
Listening to this music engages both hemispheres of our brain, which then activates the parasympathetic nervous system. The parasympathetic nervous system is responsible for our “rest-and-digest” response, which helps our mind transition from a state of anxiety to a state of calmness (“How Bilateral Stimulation Works to Reduce Anxiety“). The superior colliculus and the mediodorsal thalamus tune in, resulting in the recollection of happy memories.
This screenshot is of the video from YouTube that I’ve been listening to regularly for the past few months. When I listen to this kind of music, it feels like the auditory stimulation scratches an itch in my brain.
As someone who becomes anxious often, listening to bilateral stimulation music has been extremely beneficial for me!
