neuropsychology Flashcards
what theories and studies are present in this theme
1)Lateralisation of function
2)Damasio et al 1994
3)Sperry hemisphere reconnection 1968
What does the cerebrum do
it contains higher processing in the brain
List all 5 functions(parts) of the brain
-Frontal lobe
-temporal lobe
-occipital lobe
-parietal lobe
-cerebellum
what cortex is present in the parietal lobe?
somatosensory cortex
what does the parietal lobe do
It deals with of perception of things/people and memory
what does the cerebellum do
It deals with coordination, balance and movement
what does the frontal lobe do and its cortex
mention motor cortex
in charge of making decisions and impulse control
what is lateralisation of function
this suggests that the two hemispheres each have a function that is specific to them so them.
Asymmetrical definition:
Each hemisphere cant perform the others tasks/ not equal
features of LEFT hemisphere
*hint women
-logical thinking
-speech
-incharge of right hand
- has right visual field
- understanding of language and what is heard
-Broca’s area
features of RIGHT hemisphere
*hint men
-creativity
-musical skills
-spatial skills
-in charge of left hand
-left visual field
-recognising faces
Broca’s area VS spatial awareness
Broca’s area- in left that controls speech
Spatial- in right that navigates the environment
What is the role of the corpus callosum
mention it being a thick bundle of nerves
it allows messages to be passed from the right hemisphere to the left hemisphere and vice versa
what are the sex differences in brain lateralisation, females VS males
*3 of them
-women have a thicker corpus callosum suggesting that they use both hemispheres while men only use one
-Men are able to do spatial skills
-women are better at language tasks
what is the central nervous system made up of
spinal cord and brain
what does the peripheral nervous system do *the body
makes the body do actions the brain is telling it to do
what are synapses
A gap between 2 neurone that allow passing of neurotransmitters
synaptic transmission- the process
what could happen to our brain if neurological damage occurs
-messages passed around in the brain may be damaged
-have a significant impact on how a person behaves
What is Agnosia
This is a problem in the way the brain processes sensory information
what is Visual agnosia and what part of the brain is it damaged in
mention Parietal lobe
this is when the person can see perfectly fine but cant understand what they are seeing. They find it hard to recognise the object.
symptoms of visual agnosia
-not recognising the colour of the object
-not able to name the object
-not able to recognise familiar places
what is prosopagnosia
*hint faces
The inability to recognise faces/ face-blindness
Propsopagnosia can be caused by damage to a part of the brain near the back of the temporal lobe next to occipital known as ______________________
*FFA
Fusiform Face area
symptoms of prosopagnosia
-seeing all faces as the same
-cannot recognise faces they know very well
How does damage to the brain affect the pre frontal cortex
*3
-makes it difficult to control emotions
-personality may change
-committing of crimes
What were the aims of Damasio et al (1994)
*hint 2 aims
-to discover areas rather than the frontal lobe, that had also been damaged
-to map to the path the iron rod took
how many entry points and exit points were discovered in the study
20 entry points
16 exit points
5 possible paths
