studying
for
an
important
test.
Yozib olish va solishtirish
On
the
big
day,
you
wait
nervously
as
your
teacher
hands
it
out.
You're
working
your
way
through,
when
you're
asked
to
define
'ataraxia.'
You
know
you've
seen
it
before,
but
your
mind
goes
blank.
What
just
happened?
The
answer
lies
in
the
complex
relationship
between
stress
and
memory.
There
are
many
types
and
degrees
of
stress
and
different
kinds
of
memory,
but
we're
going
to
focus
on
how
short-term
stress
impacts
your
memory
for
facts.
To
start,
it
helps
to
understand
how
this
kind
of
memory
works.
Facts
you
read,
hear,
or
study
become
memories
through
a
process
with
three
main
steps.
First
comes
acquisition:
the
moment
you
encounter
a
new
piece
of
information.
Each
sensory
experience
activates
a
unique
set
of
brain
areas.
In
order
to
become
lasting
memories,
these
sensory
experiences
have
to
be
consolidated
by
the
hippocampus,
influenced
by
the
amygdala,
which
emphasizes
experiences
associated
with
strong
emotions.
The
hippocampus
then
encodes
memories,
probably
by
strengthening
the
synaptic
connections
stimulated
during
the
original
sensory
experience.
Once
a
memory
has
been
encoded,
it
can
be
remembered,
or
retrieved,
later.
Memories
are
stored
all
over
the
brain,
and
it's
likely
the
prefrontal
cortex
that
signals
for
their
retrieval.
So
how
does
stress
affect
each
of
these
stages?
