Occipital Cortex • VISION – Primary visual cortex – initial processing – Visual association cortex -- higher order processing of visual information. Visual Cortex overview

Forward Connections Parietal Temporal Visual overview. pdf

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.

Parietal “Where” System • V 3 – perception of shape • MT (V 5) – small moving objects, moving edges • MST – rotation, head movements, movement against background • V 4 – perception of color, visual attention Detail #1 Detail #2

Parietal Lobe

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.

Motor Pathways

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.

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. ”

Superior Parietal Lobe in Writing • Activation – Left – Superior and inferior parietal cortex – Supplementary motor cortex – Premotor cortex – Sensorimotor cortex • Activation – Right – No Significant sites of activation Surface Rendering

Keep in Mind… • How was brain structure formed – Developmentally – Evolutionarily • How does circuit create the human experience – System level – Neuron level
