Zusammenfassung der Ressource
Localisation of
function in the
brain
- Phineas Gage case study
- rail road accident, helped aid understanding about brain localisation
- Iron pole through
cheek
- caused a personality change (rude and aggressive)
- must be careful about not generalising findings
- Hemispheric lateralisation
- left hemisphere
processes
information from
the right side and
vice versa (contralaterality)
- Brocas area- producing speech
- Wernickes area- understanding speech
- auditory centres-
receives
information from
the cochlea. Left
ear information
goes to the right
auditory cortex etc
- Evaluation
- Equipotentiality
- Ashley could not find
a specific area of rats
brain that were
responsible for
specific memories
- wary about
applying
animal studies
to humans
- plasticity
- intact healthy areas of cortex to
take over cognitive functions of
the brain damaged areas
- degree of
brain
damage is
not
caused by
localisation
of
damage
but
the
extent
of
the
damage
- importance of communication
- brain areas
may be less
isolated than
first thought
- eg Wernicke stressed how brain areas were
interdependent
- damage to brain area connections causes lower cognitive function
- damage between visual and wernickes lowers reading ability
- evaluation
- Brocas area not
solely responsible for
speech
- MRI scans in the late
1800s show damages
to other areas of
brooks areas too
- Aphasia
- inability to
understand or
produce speech
- Individual differences
- Baheveliar
- differences in activation
across the right
temporal lobe and left
frontal, temporal and
occipital lies during a
silent reading task
- reported a greater use of language by women
is reflected in their proportionally larger brooks
and wernickes area
