Let
me
start
with
the
brain
and
the
functions
of
learning
and
memory,
Yozib olish va solishtirish
because
what
we've
discovered
over
the
past
10
or
so
years
is
that
you
need
sleep
after
learning
to
essentially
hit
the
save
button
on
those
new
memories
so
that
you
don't
forget.
But
recently,
we
discovered
that
you
also
need
sleep
before
learning
to
actually
prepare
your
brain,
almost
like
a
dry
sponge
ready
to
initially
soak
up
new
information.
And
without
sleep,
the
memory
circuits
of
the
brain
essentially
become
waterlogged,
as
it
were,
and
you
can't
absorb
new
memories.
So
let
me
show
you
the
data.
Here
in
this
study,
we
decided
to
test
the
hypothesis
that
pulling
the
all-nighter
was
a
good
idea.
So
we
took
a
group
of
individuals
and
we
assigned
them
to
one
of
two
experimental
groups:
a
sleep
group
and
a
sleep
deprivation
group.
Now
the
sleep
group,
they're
going
to
get
a
full
eight
hours
of
slumber,
but
the
deprivation
group,
we're
going
to
keep
them
awake
in
the
laboratory,
under
full
supervision.
There's
no
naps
or
caffeine,
by
the
way,
so
it's
miserable
for
everyone
involved.
And
then
the
next
day,
we're
going
to
place
those
participants
inside
an
MRI
scanner
and
we're
going
to
have
them
try
and
learn
a
whole
list
of
new
facts
as
we're
taking
snapshots
of
brain
activity.
And
then
we're
going
to
test
them
to
see
how
effective
that
learning
has
been.
