Q

T/F the one-to-one relationship between structure and function is applicable to all functions?

Q

When does the frontal lobe start degenerating with ageing?

A

Early on: it’s one of the first parts

14
Q

Which hemisphere is more specialised for language?

15
Q

What are some main structures involved in emotions

A

Limbic system (amygdala)

Hippocampus

Cingulate

Hypothalamus

16
Q

Which artery supplies the medial prefrontal cortex?

A

The anterior cerebral artery

17
Q

What are same positive symptoms of executive dysfunction?

A

Social disinhibition

Impulsivity

High distractability

Emotional instability

Perseveration

Hypergraphia

19
Q

Do a greater proportion of left or right handers do use their left brain for language?

A

Right - 95%

Left - 70%

19
Q

What is observed in the orbitofrontal cortex of patients with depression?

A

Smaller volume

20
Q

What is the difference between sensation and perception?

A

Sensation is sensori-neural encoding of incoming physical information while perception is the interpretation of that information

21
Q

What are some negative symptoms of executive dysfunction?

A

Lack of concern

Not finishing tasks

Deficient empathy

Restricted emotion

Lack of initiation

22
When carrying out tasks, highly impulsive people tend to display what pattern of execution?
High speed but high frequency of errors
24
Lesions in the oritofrontal cortex is associated with what?
Lack of the ability to recognise and outwardly express emotions (lesion on the right side have a greater effect)
26
What is the general function of the dorsolateral pre-frontal cortex?
Tradition executive functions ie Working memory Response selection Planning and organisation etc
27
What is the stroop test?
The word and colours test: tests inhibition
28
What is the James Lange theory of cognition and emotion?
We experience emotion relative to physiological state eg happy because we smile
30
What is Kluver-Bucy syndrome?
Lamenes/loss of fear do to bilateral, anterior temporal lobectomy (amygdala is lesioned)
31
Is executive dysfunction and frontal dysfunction the same thing?
No
32
What is the major role of the medial prefrontal cortex?
Emotional - motivational interface
33
What are the 3 unit in Luria's brain behaviour theory?
1. The brainstem and associated areas - arousal and muscular tone 2. The posterior corticol region - reception, integration and analysis of sensory information 3. Frontal and prefrontal region - planning, execution and verifying of behaviour
