11. Forward Connections What-Where pathways
Parietal: spatial orientation, attention (where pathway).
Temporal: recognition (what pathway).
Patients with temporal lobe lesions are aware that there's a problem and they develop strategies to compensate for it. Parietal patients often unaware of their deficits.

12. Parietal “Where” System
V3 – perception of shape
MT (V5) – small moving objects, moving edges
MST – rotation, head movements, movement against background
V4 – perception of color, visual attention
Different sets of neurons in V1 project to V2, which in term project to there areas in the visual cortex
High contrast, low spatial resolution, high temporal resolution

13. Parietal Lobe

14. Parietal Lobe
PERCEPTION: Complex aspects of spatial orientation and perception.
TOUCH: Primary somatosensory cortex -- initial cortical processing of tactile information.
LANGUAGE: The inferior parietal lobule of the left hemisphere (w/ temporal lobe) -- comprehension of language.

20. Parietal Lobe
PERCEPTION: Complex aspects of spatial orientation and perception.
TOUCH: Primary somatosensory cortex -- initial cortical processing of tactile information.
LANGUAGE: The inferior parietal lobule of the left hemisphere (w/ temporal lobe) -- comprehension of language.

21. Wernicke’s Area
Rear of the parietal lobe (combined with temporal lobe)
Important for understanding the sensory (auditory and visual) information associated with language.
Damage to this area of the brain produces "sensory aphasia.”
Patients cannot understand language but can still produce sounds
