Parietal Lobe
PE, PF, PG
From superior to inferior, what is the order of PE, PF, PG?
Parieto-temporal-occipital crossroads
PG is also known as...?
Primary somatosensory cortex (S1)
The anterior parietal lobe is also known as the...?
Association cortex - it integrates visual, auditory, and somatosensory info
The posterior parietal lobe is an example of an...?
PE, M1, premotor, PG, S1 input
What 5 regions does PF receive input from?
Visual, auditory, proprioceptive, somatic, vestibular, oculomotor, cingulate input
What 7 types of input does PG receive?
Postcentral gyrus, superior parietal lobule, inferior parietal lobule (all form parietal operculum)
What are 3 principal areas of the parietal lobe?
Visual control of grasping
What do the parietal reach regions (PRR) process?
Process and integrate somatosensory and visual info
What is the broad function of the parietal lobe?
Somatic sensation and perception
What is the function of the anterior parietal lobe?
Spatial navigation; use spatial info to guide behaviour
What is the function of the posterior parietal lobe?
Central fissure
What landmark marks the anterior border of the parietal lobe?
Remaining areas of the parietal lobe
What makes up the posterior parietal lobe?
Cingulate gyrus
What marks the medial border of the parietal lobe?
Parieto-occipital sulcus
What marks the posterior border of the parietal lobe?
Sylvian fissure
What marks the ventral border of the parietal lobe?
Intraparietal sulcus (cIPS)
What processes saccades and visual control of grasping?
Angular (posterior) and supramarginal gyri (anterior)
What two gyri make up the inferior parietal lobe?
Somatosensory input; M1, SMA, premotor, PF output
What type of input does PE receive and what 4 regions does it project to?
Dorsal visual stream - vision for action
What visual pathway is PG especially important in?
Between superior parietal lobule and inferior parietal lobule
Where is the intraparietal sulcus located?
