damage
to
a
specific
area
and
you
cant
talk?
Maybe
that
area
controlled
speech?

4. This
lesson
•
Explain
the
different
roles
of
Broca’s
area
and
Wernicke’s
area
•
Explain
studies
of
aphasia
including
Broca’s
aphasia
and
Wernicke’s
aphasia
•
Explain
the
contribution
of
aphasia
studies
to
our
current
understanding
of
brain
functioning

5. Language
Centres
–
Le6
Hemisphere
Broca’s
Area
–
speech
production
Wernicke’s
Area
–
speech
comprehension

6. Broca’s
Area
 Broca’s
Area
 Located
in
the
frontal
lobe
of
the
LEFT
hemisphere
only
 Production
of
articulate
speech,
clear
and
fluent
 Moves
the
muscles
that
are
required
to
speak
 Involved
in
analysing
the
grammatical
structure
of
sentences,
helps
us
extract
meaning
from
language

7. Broca’s
Aphasia
 Damage
to
broca’s
area
 Broca’s
aphasia
(non
fluent
aphasia)
=
Trouble
with
speech
production,
speech
consists
of
very
short
and
simple
sentences,
mainly
verbs
and
nouns
 Reading
and
writing
not
as
effected
(can
be
in
some
cases
though)
 Deaf
people
can
sometimes
have
difficulty
signing
if
broca’s
effected.
Although
this
depends
on
whether
they
were
deaf
from
birth…..

9. Test
for
Broca’s
Aphasia
‘stool,
is
it
boy,
is
it
that
landing
down,
girl
is
laughing,
and
cookie
jar……….ok
um…..window….curtains
and

the
garden
and

and
um

and
the
two

of
a,
two

of
ah,
two
cups
of
ah,
coffee
or
um….empty
um……..cupboard
and
cupboards
…..um……washing…..flashing
and
um
earth
to
roof’

10. Wernicke’s
Area
 Located
in
the
temporal
lobe
of
the
left
hemisphere
only,
next
to
the
primary
auditory
cortex
 Involved
in
the
Interpretation
of
speech,
referred
to
as
the
language
comprehension
center
 Vital
for
locating
appropriate
words
from
memory
to
express
meaning

11. Wernicke’s
Aphasia
 Damage
to
Wernike’s
area
 Wernicke’s
aphasia
(fluent
aphasia)
=
Trouble
with
speech
comprehension.
Also
cant
produce
meaningful
sentences,
can
string
words
together
but
what
they
say
is
nonsensical.

13. Test
for
Wernicke’s
Aphasia
‘Mother
is
away
here
working
her
work
to
get
her
better,
but
when
she’s
looking
the
two
boys
looking
in
the
other
part.
She’s
working
another
time.’

14. Right
hemisphere
and
language?
 Patients
with
left
hemisphere
damage
can
sometimes
still
use
emotive
words
and
swear!
 Emotion
more
a
right
hemisphere
function
 Also
sometimes
can
sing
what
they
cant
speak!
 Music
more
a
right
hemisphere
function
