Parietal Lobe
-Somatosensory association area -Parietotemporal association area
Parietal Lobe - Primary Somatosensory Cortex
-Surface of the postcentral gyrus = Trunk, UE, face -Surface of the posterior paracentral gyrus = LE
Parietal Lobe - Primary Somatosensory Cortex
-Perception of ____ via the ____ then relays the information to other regions.
Somatosensation
Thalamus
Parietal Lobe - Primary Somatosensory Cortex
Termination of ____
Spinothalamic
Dorsal coumn-medial lemniscus
Ventral trigeminothalamic pathways
Parietal Lobe - Primary Somatosensory Cortex Injury
What happesn with especially tractile and proprioception. Still have a crude awareness if thalamus intact. Sensory-discriminative aspect of pain is also transmitted to the secondary somatosensory cortex and insula, thus localization may still be possible although intensity and quality?
Loss of somatosensory acuity
Parietal Lobe - Secondary Somatosensory Cortex
- Located just inferior to the base of the primary somatosensory cortex and deep inside the lateral sulcus.
- Has representation of ______ along with somatosensory association area with important connections to the insula.
- Area of _______ along with the primary somatosensory cortex
Body image
Pain localization
Primary Somatosensory Cortex
Parietal Lobe - Secondary Somatosensory Cortex Injury
-Associated with _____
Eating disorders
Parietal Lobe - Somatosensory Association Area
-What is putting somatosensory stimuli (tough and proprioception) together to recongize objects?
Stereognosis
Parietal Lobe - Somatosensory Association Area Dysfunction
- Lesion: _____
- ______: altered body image - may be associated with eating disorders
Asterogenosis
Altered activity
Parietal and Temporal Lobe: Parietotemporal Association Cortex
- Integration of visual, auditory and tactile information ______
- Keeps tract of relationship between the body and the environent, while accounting for ____
Multimodal - Where it is, how it is used?
Attention, motivation, relevance of objects
