Frontal association cortex

• Intelligence

• Personality

• Behaviour

• Mood

• Cognitive function

Parietal association cortex

• Spatial skills

• 3D recognition
  - Shapes
  - Faces
  - Concepts
  - Abstract perception

Temporal association cortex

• Memory

• Mood

• Aggression

• Intelligence

Non-dominant hemisphere (right)

• Non-verbal language (e.g. body language)

• Emotional expression (tone of language)

• Spatial skills (3D)

• Conceptual understanding

• Artistic/Musical skills

Effects of injury

• Loss of non-verbal language

• Speech - lacks emotion

• Spatial disorientation

• Inability to recognise familiar objects

• Loss of musical appreciation

What does the planning/premotor area contain

Homuncular representation to plan motor movement to send to the motor cortex

What is broca’s area in charge of

activates muscles for smooth vocalisation

What is exener’s area in charge of

planning hand movement for hand writing

shape and func of the primary motor cortex neurons

big and triangular. activate muscle

shape and func of the primary somatosensory neuron cortex neurons

small granule cells. receive signals

What is supra marginal gyrus in charge of

reading the written word

What is angular gyrus in charge of

formulate writing

shape and func of primary auditory cortex

cylinder. divide periphery information to tones and tines

wernickes area function

interpret sentences like a secondary auditory cortex

what is a cortex

where neurones or cell bodies are localised

what is a fasciculus

a bundle of white matter that conduct signals between major brain regions
