hai friends,i am very happy to inform you,that glias are playing main role in brain cleaning,in the name of glymphatic.recently investigated by dr.nedergardd.normally glia astroytes-ferry nutritious blood to neurons,back waste from neurons to blood vessels,maintain good ions in synaptic cleft,produce neurotransmitters,atp,glutamate,cleans wastage,improves brain plasticity,functions are myriad.glymphatic system,letting fluid flow rapidly through brain,and controls the flow of cerebra spinal fluid ,-CSF-,a clear liquid surrounding the brain and spinal cord,clears toxins from CSF.dr maiken nedergarrd,md,d.m.sc,co director of the center for translation neuro medicine at the university of rochester medicle centre.
only recently have scientists shown that sleep is important for strong memories.dr.n. and her colleagues unexpectedly found sleep may be also be the period when brain cleans itself of toxic molecules.sleep is essential for forming and consolidating memories and that is plays a central role in the formation of new neuronal connections ,and the pruning of old ones.
accumulation of toxic by products of our body,are cleared by the body's lymphatic system .this system serves as the body's custodian.due to blood-brain barrier-BBB-system lymphatic system had no effect on brain.glymphatic system,depends on glial cells homoeostasis,and its function as a sort of parallel lymphatic system,recycles brain waste,beta-amyloid&tau to an individual cell level.in a sleeping brain,waste was being cleard two times faster.no inflow ofCSF into the brain in awaken stage.when our sleep is disturbed,whatever the cause,our cleeningsystem breaks down.the faster the fluids clear the decks,the more effectively the metabolism functioning.daily use of anaesthetics are too dangerous.
dr.n says,it is suggested that the space between brain cells changed greatly, between conscious and unconscious states.glias control CSF through glymphatic system by shrinking or swelling.the space between brain cells increased by 60% when we asleep or anaesthetised.we need sleep to cleans up the brain.astroglias, are more specifically ,long projections,they extended that envelop ,the brain vasculture.theese end feet densly express the water channels ,which allowed astrocytes to act as intervening,couplers of abulk fluid flow.in the image astrocytes-green-,with expression on astrocyte end field-purple-,a surrounding cerebral vasculature-white-.
main concept of glia gym meditation practises are to stimulate and strengthen the three functions-circles-of glia neurons.1)oligodendrocytes(CREATION),2)astrocytes(ADMINISTRATION),3)micro(DISTRUCTION).helps as an alternative system,supportive to main.enzoy glia gym&expand your brain plasticity.rewrite this topic,to fix it in your long memory circle.
