Originally posted by kirksey957I'm not sure what it is called, but it is the same region that kicks in when you leave a bar at midnight, laughing with friends and see a cop car in the parking lot. Your head bobs, your tongue falls out of your head, what was your left hand opening the car with a key suddenly becomes a right hand flipping a bottle lid over the top of the cop car... Awful mess.😕 On a more serious note, I believe it's called the Dancius Oblongotus Rythemic Madula Cortex. You either got it or you ain't. Lay persons have been known to abbreviate this to "the Moves".😵
Can someone tell me what part of the brain is fooled when you take your right leg and make circles with it going clockwise and while you are doing that make a 6 with your right arm. If you do this, you will see what I mean. Thanks, Kirk

If you could explain the effect then I might have a stab at trying to explain what happens in the brain 😉

this is the version I've heard - it's very similar:
sit with you legs crossed & rotate your right foot (at the ankle) clockwise (make sure it's clockwise!).
with your right hand draw a number 6 in the air. You should find that your right foot is now going in the opposite direction. I find it takes concentration to stop my foot direction changing, and even then the circles becaome jerky & not smooth due to the forced effort.
Hope that explains the effect, now explain the brain 😉

Yes, that is the way it is supposed to happen. It is impossible to get them going in opposite directions. As for Sir Lose Alot and Cheshire Cat, they aint right in the head. The answer I was looking for was the point of decussation in the brain stem. Good luck in life Sir Lose a Lot and Cheshire Cat.😉 Kirk
this is just totally a guess from someone who knows nothing:
Concider that most movement is controlled by antagonistic muscles, which are muscles (or groups of muscles) in pairs that pull in opposite directions, for example your bicep bends your arm at the elbow, your tricep straightens it again - when you 'flex' your muscles what you are doing is working both of the antagonistic pair at the same time, so they are bulging and working without actually making you move.
Anyway, if simple joint movement (up or down) is only 2 muscles, concider how complicated a sequence of commands it must be to get a joint to do a circle (360 degrees) - you have to get all the muscles that control the joint pulling or relaxing in just the right amount in the right sequence. Like most movement, the actual muscle use is controlled by the subconcious, and to learn something intricate like this I bet there's a specific part of the brain storing the "relax and tense" sequence to allow you to do a circle. But only 1 per half of the brain.
Because your right side of you body is controlled by the left side of the brain, if you start turning your right foot clockwise the part of your brain that has learnt to do circular movement goes into clockwise mode. You then try to draw a 6 with your right hand (which also uses the left half of your brain) in an anticlockwise circle, and without your concious mind knowing it, the "how to do a circle" part of your brain a new command to flip into anticlockwise mode, meaning that you foot changes direction.
This would explain why I am able to keep my foot going clockwise with effort, yet the movement becomes jerky - because I keep my foot going clockwise by using a different part of the brain that hasn't learnt how to do/doesn't control smooth circles, just normal movement. I guess with enough practice second part of the left side of your brain could learn how to do circles, so you could do 2 different directions at once. Or maybe some have this naturally.
That's a load of rubbish from an amateur. Now I'm waiting for someone who knows something to tell me I'm wrong...

Originally posted by belgianfreakOk, I'm not too up on the basic neuroanatomy of the spinal cord and such like, having just done a quick search for Kirk's point of decussation... At a systems level though, the motor strip (an area of the cortex crossing the top of the head and just behind the ears) would most likely issue the commands for both types of movement, in conjunction with the cerebellum ('little brain', a structure at the back of the head underneath the visual cortex). The motor cortex is required to move muscles at a gross level ,projecting directly to the skeletal nerves controlling individual neurons, and the cerebellum is the structure controlling both the learning and storage of fine motor movements, such as catching or dancing. If we performed one type of movement separately after the other, we would have no trouble, since the commands are issued distally in time, but if we try to perform both together we introduce interference in the system. This interference causes the motor command to the foot to get translated into an anti-clockwise motion, as both motions separately are controlled by the same pathway (lateral corticospinal tract). If the commands were issued beneath the point of decussation (point where neurons cross over to controlling the same, and not the other, side of the body), there would be no interference and it would be possible to perform the two maneuvres simultaneously.
