Asymmetry in Brain Function and Depression

Previous research has suggested that depression is due to decreased activity in the frontal cortex.  Some research has suggested that a decrease in activity of the left frontal cortex is most likely to produce a depressed mood.  A study published in Neuroscience showed that depressed patients had half the vestibular function of the right side compared to the left, and the controls did not show significant asymmetries.

So what does this mean?  The right vestibular system (inner ear and the brain circuits associated with it) is the major driver of left frontal brain activity.  If one does not have enough right vestibular activity then it will lead to a decline in left brain activity.  This is called diaschiasis, and may be at the root of depression in some individuals. The good news is, the brain is plastic.  This means the brain is able to adapt, change, rewire and improve its function with the correct stimulation (mode, frequency, intensity, and duration).  This is the basis of functional neurology.  Check out the video on functional neurology at the link below.
