In recent years,
a plethora of studies have been conducted in the field of neuroscience using
frequency magnetic resonance imaging (fmri) to study the effects of acupuncture
on the brain. One area of focus is the
Default Mode Network (DMN), which was first introduced to neuroscience in 2001
and identifies a network of brain regions involved in a resting state. Characteristics of DMN activation include
resting, daydreaming, allowing the mind to drift freely, and introspective
awareness. This is in contrast to the
Task Positive Network (TPN) where the brain is actively involved in a
task. This includes working, problem
solving, thinking of future events, and extrospective awareness. In a healthy individual, these two networks
can toggle freely as needed, and are anti-correlated, meaning when one is
active the other is inhibited and vice versa.
Ample time spent in each mode is necessary for optimal brain
functioning. When enough time is spent
in the DMN phase, the brain recharges itself resulting in better performance,
decision making, and clear thinking while performing tasks. Studies show that in various mental disorders
such as anxiety and depression, there is a lack of cohesive communication
within the DMN.
As this topic is being studied scientifically,
most mental disorders are being shown to involve a disruption in the DMN such
as depression, ADHD, anxiety, schizophrenia, autism, Alzheimer’s and many
more. Acupuncture is being shown to
activate the DMN, restoring healthy communication among its involved brain
regions, giving rise to improved mental states. These results have positive implications on
acupuncture’s ability to treat a variety of mental disorders. As more studies are done, and eastern
medicine and western medicine collaborate, perhaps a more holistic approach to
treating illnesses will make its way into mainstream medicine, and the value of
balancing work with rest will become a staple in maintaining good health.
