Parietal and Occipital Lobes

Week 5: Parietal Lobes (Chap 5) and Occipital Lobes (Chap 6)

Parietal Lobes (Chap 5)

Anatomical items: anterior and posterior regions

1. anterior region - foreward most/anterior border is the posterior central sulcus/gyrus

• primary somatosensory cortex (sensory strip)
  
• secondary somatosensory cortex
• tactile perception
• body sense

2. posterior region - no clear/hard borders

• ALL tertiary cortex
  
• spatial orientation/spatial neglect
• some cases of visual agnosia
• APRAXIA; disorder of practical/purposeful/intentional motor behavior
• cross-modal integration/language (PTO, remember?)
  

Occipital Lobes (Chap 6) - the visual perception lobes

• primary - basic visual functions
• secondary - visual perceptual functions
• tertiary - higher order perception and inter-sensory integration (PTO, remember?)
