1
Q

What is meant by the psychophysiological state?

A

Incorporation of conscious thought into physiological state eg heart rate increases when scared

1
Q

Which artery is the dorsolateral pre-frontal cortex mainly supplied by?

A

Middle cerebral artery

2
Q

What is the Cannon Bard theory of emotion?

A

You can experience emotion without expressing it

2
Q

What is akinetic mutism?

A

People have to ability to do things but lack the motivation

3
Q

What are the general functions of the temporal lobe?

A

Audition, language, memory, music and emotion

4
Q

Which hemisphere is more specialised for visuospatial functioning?

A

The right

4
Q

What is the function of the orbitofrontal cortex?

A

Controls inhibition - emotion, social and cognitive

Impulsivity

Linked with the limbic system

5
Q

Which arteries supply the orbitofrontal cortex?

A

The middle and anterior cerebral artery

6
Q

What are the core emotions?

A

Sadness, fear, anger, disgust, happiness (surprise)

6
Q

A hypocampus of reduced volume is associated with what?

A

Genetic predisposition to depression

7
Q

What is cognitive appraisal?

A

The way to think about a situation will effect how you go onto perceive it

8
Q

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

A

False, while is does work for more simple functions eg smell it doesn’t hold true for more complex traits like the ability to concentrate.

9
Q

What are the general functions of the parietal lobe?

A

Somatic and visuospatial representations

10
Q

What are the general functions of the frontal lobe?

A

Planning, execution and regulation of behaviour

11
Q

What are the general functions of the occipital lobe?

A

Vision

(visuospatial too)

12
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?

A

The left

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
Q

When carrying out tasks, highly impulsive people tend to display what pattern of execution?

A

High speed but high frequency of errors

24
Q

Lesions in the oritofrontal cortex is associated with what?

A

Lack of the ability to recognise and outwardly express emotions (lesion on the right side have a greater effect)

26
Q

What is the general function of the dorsolateral pre-frontal cortex?

A

Tradition executive functions

ie Working memory

Response selection

Planning and organisation etc

27
Q

What is the stroop test?

A

The word and colours test: tests inhibition

28
Q

What is the James Lange theory of cognition and emotion?

A

We experience emotion relative to physiological state eg happy because we smile

30
Q

What is Kluver-Bucy syndrome?

A

Lamenes/loss of fear do to bilateral, anterior temporal lobectomy (amygdala is lesioned)

31
Q

Is executive dysfunction and frontal dysfunction the same thing?

A

No

32
Q

What is the major role of the medial prefrontal cortex?

A

Emotional - motivational interface

33
Q

What are the 3 unit in Luria’s brain behaviour theory?

A
  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
