8- Higher Cortical Function Flashcards
How layers is the cerebral cortex made up of?
Six
What are the main functions of the frontal lobe?
Motor control, expression of speech, behavioural regulation, cognition, eye movements and continence
Right sided motor weakness could indicate a lesion in which lobe of the brain?
Left frontal lobe
Which area within the frontal lobe (usually left) is responsible for expression of speech?
Broca’s area
Someone who has a change in behaviour where they become impulsive, inappropriate and aggressive is most likely to have a brain lesion in which lobe?
Frontal lobe
A patient has difficulty performing tasks such as complex problem solving and calculations and is found to have a brain lesion, where is it likely to be?
Prefrontal cortex of the frontal lobe
Damage to which lobe of the brain could lead to urinary incontinence?
Frontal lobe
Which functions are associated with the parietal lobe?
Comprehension of speech, sensory function, body image and attention, calculation and writing
What are the functions associated with the temporal lobes?
Hearing, olfaction, memory, emotion
In 95% of people which hemisphere is dominant?
The left cerebral hemisphere
Which specific area of the brain is responsible for the comprehension of language?
Wernicke’s area
Damage to the sensory cortex would result in contralateral anaesthesia affecting which modalities?
All of them
Damage to which lobe of the brain can lead in the syndrome called ‘neglect’
Right parietal
Auditory hallucinations are most likely associated with a lesion of which lobe of the brain?
Temporal
Which area within the temporal lobe is important for the consolidation of declarative/explicit memories?
Hippocampus
What animal is the hippocampus said to resemble?
A seahorse
How which someone with broca’s aphasia respond to questions?
They have good comprehension of the question but struggle to express their answer
How will someone will wernicke’s aphasia respond to questions?
They struggle to comprehend the question but will respond fluently despite non-sensical
What is the white matter pathway connecting the broca’s and wernicke’s areas called?
Arcuate fasciculus
Declarative memory such as facts learnt for an exam tend to be stored where?
Cerebral cortex
Non-declarative memory like motor skills or emotion tends to be stored where?
Cerebellum and subcortical structures like basal ganglia
What are 3 factors affecting the consolidation of memory?
Emotional context, rehearsal, association
