Study Notes
Parietal Cortex and Associated Syndromes
- Parietal cortex is always affected in left hemispatial neglect syndrome
- Thalamic connections to association cortex come from the Mediodorsal thalamus, Pulvinar, and Ventral anterior nucleus
- Association cortex connectivity is defined by a distinct set of thalamic, cortical, and subcortical connections
- Synesthesia is a perceptual phenomenon where stimulation of one pathway leads to experiences in another
- Lesion studies disrupt function and are messy, lacking fine spatial resolution
- Functional studies provide real-time assessment of function in living patients
- Transcranial Magnetic Stimulation (TMS) is a technique used to stimulate neurons in the brain
- Parietal cortex participates in the construction of spatial representations guiding attention and movement
- Lesions in parietal cortex can result in contralateral neglect syndrome
- Right inferior parietal lobe injury can lead to deficits in attention to the left side of space
- Right hemisphere tends to dominate attention for both sides, while left hemisphere is occupied with language
- Parietal neurons respond more intensely to attended objects than unattended ones
