A little long so my apologies in advance. Musings from a pleasant climate.
Some people have asked me what is this ‘thing’, this ‘word’ people go on about called neuroplasticity in relation to seizures. And what does it mean when people talk about ‘unlearning’ the learnt and learning new pathways. Sometimes people use these phrases interchangeably without giving any practical examples.
What follows below is one of my ‘clumsy’ analogies. I am not a medic, just someone who has functional seizures and who is learning to manage them more positively as every day passes.
Every day I learn more and understand my own unique experiences with greater clarity. Everyone’s experiences will be different. I make no claim as to the generality as to how my experiences and explanations reflect people’s individual experiences.
As we are complex adaptive creatures, every day is a new learning experience, and I embrace this innate strength which lies at the very core of that which we call being human and being alive. The emphasis is most definitely on being alive. It is a truism that if you are not in an experience of enjoying that fickle creature, which we call nature, then you are by definition not alive.
Imagine you are driving your car. A mechanical piece of engineering based on creating repetitive explosions and then using the power unleashed. Focusing the energy generated, or more correctly transferred as energy cannot be lost just transformed, onto a set of wheels that moves you forward. Yes, you are sitting in a bomb.
But that is not the point I wish to convey.
The first time you got into this functional energy translation machine, someone would have explained a couple of things. There is a spinning wheel which needs to be engaged via gears to harness the energy. You engage this by using a pedal called a clutch to go up and down the gears. There is another pedal which makes the spinning wheel go faster as you increase your momentum and achieve a velocity which is greater than the frictional resistance of the ground allowing you to move in the direction you choose by turning another wheel.
More likely, someone would have said. There a three pedals. A gear stick and a steering wheel. You put your feet on the pedals. One to go. One to stop and one to change gears. Use your left hand to change gears. Turn the steering wheel so that the wheels point in the direction you want to go. When you are ready depress the clutch, change into low gear and then depress the go faster pedal. When you want to stop. Depress the brake pedal. One last instruction. Avoid objects such as trees and walls and especially people. Now off you go, you have learned how to drive and it’s your bomb to fly.
After a number of lessons, of trial and error, you learn all of this, assimilate it, get a feel for how the functional aspects of the car work and you are comfortable. So comfortable in fact, that after a reasonably short period of time, you can do all of this involuntarily. It becomes second nature. An interesting phrase if you think about the word second. You can allow this to become a safe learned action and after a while you just jump in the car. Turn on the ignition, and thats all you think about. The experience, the complex set of instructions have all become a learned experience.
Now over time, someone’s says to you. There is an easier way. We have a different way of doing all of the above. Just by using two pedals and a steering wheel. An automatic. Ha ha, tremendous you say. Let’s give it a go. You jump in. You put your feet by the two pedals and immediately have a blind panic. There are two pedals not three. I only have to use one foot. Which one. You put your left arm where the gear stick is and it has three positions. Parked. Go forwards. Go backwards. That’s novel.
Anyway, as you have the confidence of being able to drive a manual car and have the learned experience. You put the lever into go forward, depress the go faster pedal and off you go. Again avoiding objects such as trees, walls and especially people.
On your journey you find you left arm forever trying to change gears but it is not required. You also find your left foot wants to do something but it is not required. You struggle as you have to unlearn the previous learned experience. After a while you master this and you say to yourself, well this is easy and a lot less hassle than driving a manual car. You are content. You unlearn the old way and learn a new way.
The functional experience and the way that you do things has now become by default the way to drive an automatic car. It used to be how to drive a manual car.
One day though, you have occasion to get back into your manual car. You climb in and settle down for the journey. This may be the result of the automatic car having a functional day off. As a thought experiment do cars have functional seizures.
As an aside, for film buffs, the original Bladeruuner film (okay I am showing my age) was based upon a thought experiment of ‘Do Androids dream of electric sheep”. Ridley interpreted this dysfunctional alternative brilliantly, although Isaac Asimov may have railed against it, as the Laws of Robotics, as outlined in his trilogy of novels called Foundation, were clearly not followed. But I digress.
Back to my analogy.
You say to yourself, simple really, driven one of these for many years before I had an automatic. No problem after all it is just functionally the same as an automatic.
But suddenly you find that the car is stalling, you depress the wrong pedal and suddenly the car is functionally not behaving as you remember. In fact it is not doing the things it is meant to do automatically. Strange sounds are coming from the engine as you depress the accelerator pedal without the functional gear being engaged. The car wont move forward and when it does, it is jerky and not smooth. It is also doing things automatically or involuntarily which you really have no control over.
You then think to yourself, so what I need to do, is to switch off the involuntary actions which are the learned response of how to be in a functionally automatic car which ‘knows’ how to do things in the background and which sometimes does things you didn’t voluntarily initiate.
Then having switched off this learned involuntary response, you say to yourself, I now need to really concentrate on performing the voluntary actions of driving a functionally manual car and to re learn new pathways.
After a few bumps in the road, you do so, and you have unlearned the learned and have learnt new neural pathways.
A long winded muse on the chemical powerhouse which we call our brain exhibiting neuroplasticity. Rather than complex hydrocarbons, such as petroleum, which we feed our car, we feed our brain complex carbohydrates and oxygen with the spark plug of cellular activity being based upon a missing electron of the oxygen molecule.
With thanks to my wife Miranda who inspired me to explain this analogy and who had to re-learn how to drive a manual car recently in the dark.
