Until recently, I never remembered dreams. Then, one morning I woke up in the middle of one that was so intense I allowed it to enter my consciuosness. I realised that the dream gave a very precise account of my feelings, and spent some time thinking about it.
Later, I\'ve quite often remembered dreams. Somehow, the filter mechanisms that decide what is allowed to reach my brain, have been re-programmed - from "no dreams, thank you!" to "dreams appreciated". I think this suggests that the filters are "programmed" by the brain\'s reaction to what gets through.' tekst3='';systemK='' }} var koden=startH+thStart+tekst1+systemK+thSlutt+ds+tekst2 if (tekst3.length>4) koden=koden+rs+'Use in dance:'+ds+tekst4+rs+'Effects of training:'+ds+tekst3+sluttH parent.tekst.document.open() parent.tekst.document.write(koden) parent.tekst.document.close() } // -->

Effects of dance training:
NERVOUS SYSTEM

Nervous system: A network of cells that transmit signals

How the nervous system "learns"

Keyword: synaptic facilitation.

The effect of training on the nervous system is to establish / reinforce the nerve "pathways" necessary to perform a certain movement.

Movements are initiated by cerebral cortex (part of brain). New movements are controlled by cerebral cortex, and often feel awkvard till the new pathways are established and other parts of nervous system learn to facilitate the movement. (Pyramidal system, alpha and gamma).

Training improves neuro-muscular coordination. 'Repetition reinforces these patterns and improves coordination, speed and skill.' This is why repeating movements makes your body able to do them more efficiently.

Structure of nervous system

This is an attempt to illustrate this simple classification of the nervous system (subdivisions of peripheral only). Please click hotspots to see a brief recapitulation of what the different parts do, how they learn and why dancers need them:
