SRINU-KRIYA-DYNAMIC-DECISION-MAKING-(soul)

DYNAMIC-DECISION-MAKING-(soul)
 Hai friends,imagination or thought,in our brain triggers some of the same physicial mechanisims involved in actual sight-eyes are the compact bundle of neurons-.When you switch of the lamp and your pupils will widen to take more light.If you stepout into the sun,and your pupils will narrow.Pupils works parlley between imagination(thought) and perception.Imagination also widen&narrow your pupils.Nural process is similar.Scientists are conducting methods to study consciousnes by providing visual stimulation.Visual stimulation,mental imagery,thoght,also improves brains conscious works.Follow the sketch,visulise,thought,improve
your DDM like a sky rocket-follow our previous blogs for clarity!!!kapalabhati-rep-100-200-per minit.

SRINU-KRIYA-NANO-SCALE-TO-NEUROSCIENCE.

                                       NANO SCALE.
      HAI friennds this information may useful to the GG practitionars,with curtesy of -scalable neuroscience-thomas dean,google inc.

  • Average number of neurons in the brain=100billion(100^11).
  • Diameter of neuron=4-100um(micron)(granule,motor).
  • Ratio grey to white matter=(1.3,1.1,1.5)by age(20,50,100).
  • Percentage of oxygen consumption by white matter is6%.
  • Percentage of oxygen consumpiton by grey matter is94%.
  • Number of neocortical neurons20billion(10^10).
  • Average loss of neocortical neurons=100,000 per day(10^5).
  • Number of synapses in cortex=0.1quardrillion(10^14).
  • Number of cortical layers=6.
            Thickness ofcerbral cortex=1.5-4.5mm.
  • Total surface area of the cerebral cortex=2,500cm^2.
  • Number of synapses for a typical neuron=1000to10,000.
  • Single sodium pump transport rate=200/100Na/K ions/sec.
  • Number of sodium pumps=1000 per um^2 of membrane.
  • Total number of sodium pumps for a small neuron=1 million.
  • Voltage gated sodium channels at each node=1000 per um^2.
  • Voltage gated sodium channels between nodes=25 per um^2.
  • Sodium channels in unmyelinated axon=100 per um^2.
  • Membrane surface of a typical neuron=250,000 um^2.
Area of 100 billion neurons=25000m^2,Neurotransmitter molecules in one synaptic vessel is 5000,Action potential(1,10,100)m/sec by diameter(0.1,10)um.
