Affecting the production
of subjects, verbs and
objects.
Wernicke's aphasia.
Troubles processing
linguistic input.
Aphasiology.
Human brain differs
from most other
animals.
It is not equipotential. It
doesn't function
holistically.
It is more suceptible to
injury than animals (along
with the spinal cord.).
The damage could happen by
Blood loss due
to a stroke.
Invasive injury.
(automobile
accident)
Surgical procedures.
It's much more likely to
'go wrong' with adults
than with childrens.
Children's brains are still in
development and can tolerate
surgical changes.
Adult's brains are completely
developed and sensitive to
changes or injuries.
Neuroplasticity is lost
because localization is
complete.
Brain-related
disorders.
There are many, many
ways in which an
individual's language can
deviate dignificantly.
Two main
examples.
Stuttering.
Can happen due to traumatic events in
childhood or by the absence of
unambiguous lateralization of speech.
Autism.
It's not just a language
impairment and there are
several types.
Also has anti-social connotations.
Inherited
disorders.
The genes which carry
the human heritage for
speech are
countermanded by an
inherited defect that is
transported by the
same genetic code.
Aging.
Language usually stays
still even in old people.
The more you have to
remember, the easier it is to
forget.
Linguistic functions gradually disintegrate
together just like emotion, cognition and
personality.
Neurolinguistics.
Investigates how the human
brain creates and processes
speech and language.
It is known that in normal
brains any information in
either heimsphere is
immediately shared with
the other.
Language is
usually
represented in the
left hemisphere.
Though any information is in
both hemispheres, some brain
functions have a specific place in
the itself. (Though hey are not
just in that part of the brain).
Damage to the parallel
areas in the right
hemisphere does not
normally affect
language production or
comprehension.
