So you heard the news then changed the channel...

States of mind; I need a switch or calibration meter for my brain, something whereby I can flick my lump of grey matter into 'creative' mode or 'idle', there are times when my brain is on the wrong track for what the rest of me is doing in reality.

Or maybe my brain is trying to tell me something; I know I can force, or at least cajole it with small chocolate biscuits and cooing noises into certain states, usually with music but actually getting it to states where I can feel a change, almost like a proverbial switch has been thrown isn't so easy.
Maybe this is part of meditation, but meditation is only for a single type of change, to relax; what if I want my brain to zone out and just concentrate on what is to hand or to go hyper and just a little nuts? Is there meditation for that? Well, discounting sugar and hyperventilation... maybe, certainly you can work on training your body to do certain things, certain things become unconscious and we no longer need to concentrate on them.
As a sort of quasi example, take breathing, it's fairly fundamental to existing, we don't breath, we don't live - well not for very long or as part of some huge bio-metal iron lung machine, and frankly that’s not a kind of life I'd want. Erm, yes, oh yes, breathing - see if you start -thinking- about breathing you sometimes catch yourself having to concentrate on it to keep it going and disengaging your brain from what was previously some mundane background task becomes really difficult, now that your attention has been brought to it.
Not possibly a direct example of what I'm talking about but what I am talking about I'm not sure about, except the fact I want a seven speed gearbox brain with levers I can pull to change aspects, or I could just have a pile of different brains to use; my dance brain, my party brain, my work brain, my gaming brain. This could have problems too of course, I'm sure my work brain is going to resent the fact that it never gets to have any fun while the other brains have nothing more to deal with than possible hangovers and exhaustion, big deal. If I was my work brain I'd lobby for evenings off which means the other brains would then have to fight in an arena of death surrounded by cheering neurons to determine which brain had to go to the work; "Chew his hypothalamus!" "Pull his brainstem!" the crowd would call, cheering masses vying to see every little bit of gore splatter out from the sawdust filled pit of extreme fighting.

Still, I have worked out some stimuli to make my noggin do some things, mostly music really as it seems to have some kind of mystical connection to my psyche (I suspect my ears are involved here, but this investigation is still pending.
Other stimuli include that wonder of nature and elements, sugar. Now a sugar rush for some people is something they experience now and then, and so it used to be for me, but... ahhh, excuse me, I'll explain in a moment, a well trained brain can replicate feelings that you have, so I'm looking back now. Confusing myself slightly here, yes, right. Um, oh yes, sugar. See, the little 'ahh' was a self imposed sugar rush, or at least a feeling that was very much approximate to it. Hey, I did it again, nifty. Sugar rushes on demand... or at least the sensation... sugar rush, what is one? What it is for you, gentle viewer, I have no idea, what it is for me and how I seem to be able to replicate them at the moment is as follows...
Close your eyes, concentrate just behind your eyes and bring your centre of feeling up to around your shoulders and back of your neck, now let it slip, slowly until a warm, tingly fuzzy feeling rolls down the hairs of your arms and down your spine in a shivering little tingle.

Dang it, can't manage a third. I suppose two sugar rushes for free is good though, it's a start at least - so it seems you can train your brain or at least I can, I'm sure you can too, people have been doing it for years. But then this is one of those long meaningless rambles that is uncertified and given a no money get out clause.

You get exactly what you read on the tin.
