we found that the plane has two different functional state one state as one be

awake and that we have our surroundings and another state is one v asleep the

difference being that when we have weak the plane sensor working they had processing all

the information about our surroundings whereas the during sleep

we work very they had all of a moving all the way step in open

be a week the or sleep about eight hours every t and b or wonder

why do we need to do it even the old greek philosophers wondered why do

we need to sleep

and if you look at animals you'd find that even words and mice sleep for

a long time if we d

so that suggests that sleep has of a basic function and its needed if you

keep and ml a week that would eventually die

some ice would die if you keep them a week for several weeks that would

eventually die and be when you don't know why

so

but until such a perception of

basic biological function and our study i believe people pointed by showing yes sleep there

is absolutely essential for the movement of talk sequential portal from day to pine they

can emphatic system function very much like the garbage removal and then space "'cause" a

function of the emphatic system so that works

a subset you be had in flocks of simple spinal fluid and on the ad

tree getting into the queen that fluid this compared to the brain in between the

plate plane so what eight neutral if you are shows toxic waste product we

the dirty fluid correlate of around the means

and we'll after it is dumps into the no phase and

be delivered to the new of a that is how big we cycle obtained when

a protein likely to "'em" annoyed another toxic which model can be equated and recycled

we infuse the floor rise and the time into the serial bro spinal fluid which

we can see as f so from this technique we can see the cs f

flow through into the bright in the sleeping mice we found that the csi of

flushing to the brain

where e quickly and the properly but in the awake bring the cs f

just the paillier of floating this finding restock implication that the weight bring has more

resistance to the cs f influx

so

this leads to the thinking that probably the pats

of the cs airflow is a smaller in the a weight bright surprisingly we found

that

the spaces between the two cells increase the around the

sixty percent from awake state to the sleep state the radically the bigger space cost

a more influx

which were make the

clear trends more efficiently

so our study suggest that we need to sleep because we have a macroscopic leaning

system that remove many of the toxic waste portal from the plane
