My Mom died last September due to Parkinson’s Disease. Because of that, I keep my out for articles about PD or dopamine.
In case you don’t know about PD, here is the Wiki entry:
Parkinson’s disease (also known as Parkinson disease or PD) is a degenerative disorder of the central nervous system that often impairs the sufferer’s motor skills and speech, as well as other functions.[1]
Parkinson’s disease belongs to a group of conditions called movement disorders. It is characterized by muscle rigidity, tremor, a slowing of physical movement (bradykinesia) and, in extreme cases, a loss of physical movement (akinesia). The primary symptoms are the results of decreased stimulation of the motor cortex by the basal ganglia, normally caused by the insufficient formation and action of dopamine, which is produced in the dopaminergic neurons of the brain. Secondary symptoms may include high level cognitive dysfunction and subtle language problems. PD is both chronic and progressive.
PD is the most common cause of chronic progressive parkinsonism, a term which refers to the syndrome of tremor, rigidity, bradykinesia and postural instability. PD is also called “primary parkinsonism” or “idiopathic PD” (classically meaning having no known cause although this term is not strictly true in light of the plethora of newly discovered genetic mutations). While many forms of parkinsonism are “idiopathic”, “secondary” cases may result from toxicity most notably of drugs, head trauma, or other medical disorders. The disease is named after English physician James Parkinson; who made a detailed description of the disease in his essay: “An Essay on the Shaking Palsy” (1817).
I added the bold to explain why I look for articles about dopamine. Today I came across this one:
After they ran a small current into the wire, so that the nucleus accumbens [a dopamine center of the brain] was continually excited, the scientists noticed that the rodents lost interest in everything else. They stopped eating and drinking. All courtship behavior ceased. The rats would just cower in the corner of their cage, transfixed by their bliss. Within days all of the animals had perished. They had died of thirst.
Suddenly, I had a bit of an epiphany.
“Fake it till you make it”
“Become the change you want to be”
“Just do it”
Dopamine production is kicked off by sex and drugs and rock & roll. Or any other exciting activity.
I am sure there are dozens of similar cliches, but what clicked in my head after reading that article is your lifestyle becomes reinforcing on a neurological, chemical level.
So, if you want to get in shape, force yourself to do it for a while. Your brain will become addicted to running/swimming/biking.
If you want to be a painter, keep painting, etc.
There have been times when I thought about this concept in a vague way, but never really understood the biology behind it.
Now it makes much more sense to me. “Stuck in a rut” is more than just a phrase, your body becomes addicted to the things that make it happy. If that is World of Warcraft, riding a motorcycle, going to church, or blogging, then your body starts to become addicted to that activity.
So, plan what you want to be and just do it.
Now, I need to go for a ride.
