1
Q

Laterality of Brain Organisation

A

Bilateral anatomic symmetry between the two hemispheres
Contralateral sensorimotor control of the nervous system
Unilateral functional differences

2
Q

Cognitive Functions Mediated by Right Hemisphere

A

Attention, perception, memory, organisation, reasoning, problem solving, planning, self-awareness, orientation

3
Q

Hemispheric Specialisation - Language

A

Left hem dominant for language

neural organisation - close knit, integrated on the left, diffuse on the right

4
Q

Language Processing

A

Left hem - sequential, discrete info
- phonetics, phonology, morphology, syntax, semantics
Right hem - holistic, emotional
-Pragmatics, inferencing, prosody (emotional meaning, intonation, voice recognition)

5
Q

Right Hem Contribution to Language

A

Key role in:

  • discourse level processing and coherence
  • Inference generation
  • Production and comprehension of non-literal language
  • Prosodic and affective processing
  • Self monitoring
6
Q

Specialisation and Lateralisation - Development

A

Failure to develop a dominant hemisphere may cause development language disorders (SLI, dyslexia)

7
Q

Right Hemisphere Language Disorder

A
Begin and end conversations abruptly
Poor at maintaining eye contact 
Talk excessively 
Irrelevant, tangential, inappropriate comments 
Fail to make conversational repairs
8
Q

Pragmatic Deficits

A

Difficulty identifying speaker’s intention
Reduced ability to cooperate during conversation
- impaired turn taking, inappropriate eye contact, difficulty being appropriate in different contexts

9
Q

Emotional/Prosodic Deficits

A

Impaired ability to regulate emotions

Impaired modulation of prosody

10
Q

Discourse Deficits

A
Difficulties with both maco/miicro planning
- macrostructure (flow) of discourse 
- difficulty identifying gist of convo
- impaired coherence 
- disorganised thoughts 
- tangential propositions 
- Overly concrete
- Verbose/circumlocutory 
Impaired perspective taking/assigning prominence
11
Q

Anosognia

A

Denial of illness, no awareness of deficits, poor self-monitoring
Common following RH damage

12
Q

Non-linguistic Deficits - RHD

A

Left side neglect
Attention deficits
Visuo-perceptual deficits

13
Q

Right Cerebral Hemisphere Syndrome

A
Upper motor neurone damage - left sided weakness
Somatosensory loss to left side 
Left visual field loss
Left attentional difficulties
Dysarthria (from involvement of UMN)
Right hemisphere language disorder
