Nerves must 'shout louder' as we age

If it's on your mind and it has to do with multiple sclerosis in any way, post it here.

Nerves must 'shout louder' as we age

Postby TwistedHelix » Fri Mar 09, 2007 12:39 pm

To understand what has gone wrong with our bodies, it's crucial to understand what constitutes 'normal' nerve-muscle communication and what happens during ageing, as this prof is doing...

Dom,
I like to see that kind of simple, valid, common sense research in which you can almost be certain of the results.

Thanks for leaving me an easy one to think about when entering the weekend!

So with this information, I want to conclude that working on our fast twitch muscles (through polymetric training etc) should make the nerves "distance" that they have to shout a lot shorter. Right? Therefore making them less likely not to "hear" us?

I hope this prof eventually does research of folks of the SAME age (elder)... between those who work on their fast twitch muscles and neuromuscular reeducation and those who do not.

Right after I gained back some feeling and control in my legs, one of my more progressive doctors suggested I get a "balance board" (looks like a flying saucer) in order to help reeducate my neuro pathways. I thought he MUST be a mad man... getting a woman with nearly NO balance on something called a "balance board" seemed like a cruel JOKE.

So... I started by having my husband hold me on there. Then I moved to holding a wall. Then one long stick. Then I could move the stick sideways like a tight-rope walker. Then I could twirl the stick like a baton. And now... despite often falling over just while STANDING... I find the BALANCE BOARD to be simple. (I'm still working on closing my eyes...) (8 months of daily work on it) The neurotransmitters finally found a new path!

Now if I can just get them to do so while I close my eyes standing on even ground in the shower. :)

Hi ClancyP,

I noticed a bit of a contradiction in this article: in one sentence, the researcher talks about reduced firing rate of neurons, and then immediately talks about the muscles not listening. From this, I'm not really clear about whether one or both things are happening.
I would think it's probably more likely, (and more relevant to MS), to be the reduced firing rate of neurons. The strength and speed of a movement is directly related to the strength and speed of the electrical signal firing from the nerve to the muscle. For example, if you were gently holding an egg, and you could hear the pulses in the nerves controlling your finger muscles, you would hear "click...... click...... click", if you decided to squeeze hard and break the egg you would hear "CLICKCLICKCLICKCLICK". so you see, it's not exactly the "distance" that the nerves have to shout, more about how loud and fast they can shout.
Sometimes I think that MS sounds more like accelerated ageing in the brain than anything else.
Sounds to me like your progressive doc is a good one: he's used the phenomenon of "plasticity" to overcome your balance problems. This is where, if the bits of your brain which are used to control something are damaged for any reason, repeatedly trying to do the same movement forces your brain to make new connections and reinforce them with constant use. That's what a baby does -- strengthening the circuits which work, and discarding the ones which don't. All credit to you for sticking at it so successfully. Give it a couple more months and the job in the circus is yours :wink:

Bob,

With the weekend coming up I didn't want to blow your own mental circuits with anything too taxing. Your wife needs you, and you need her to bake you a nice "congratulations on your 1000th post" cake. (Note to all readers: please send your complaints about outdated sexual stereotyping to: Mr R Lyon, somewhere in Michigan).

Hi Dom,
Very observant! I would have missed that 1000 post milestone if you hadn't brought it to my attention!

For some reason I've been getting a lot of complaints this morning regarding my forcing my wife to slave behind a hot oven....you don't know anything about that do you?

May Dom and Bob be sentenced to a week's worth of dinners that are undercooked on the inside and more burnt than the seventh circle of hell on the outside. :wink:

But meanwhile, would someone please tell his wife to get back in the kitchen? Could of sworn I saw her with some shoes on too...

HA!

The moral of this story is that women are either much smarter or men are less smart than they are given credit for.

My wife would kill me for mentioning this but when we first started dating she invited me over for dinner.

At the dinner table she put a plate in front of me which contained black squares and something in aluminum foil. Upon my asking she told me that the black things were fried potatoes. I opened the aluminum foil to find skinless chicken breast, which when eaten had the flavor and consistancy of a warm wet washcloth. As well as I could, I acted as if it were an edible meal but in the 32 years since I've made a point of never letting her step foot in the kitchen again.
