Parietal lobe

Question 1

Parietal cortex

Answer 1

Processes and integrates somatosensory and visual information, especially regarding controlling movement.

Question 2

Postcentral gyrus

Answer 2

Responsible for processing touch and bodily sensations

Question 3

Superior parietal lobule

Answer 3

Involved in integrating sensory input, particularly for movement coordination

Question 4

Parietal operculum

Answer 4

Related to somatosensory processing

Question 5

Inferior parietal lobe (supramarginal gyrus and the angular gyrus)

Answer 5

Plays a role in language, spatial processing, and visual-motor coordination

Question 6

Anterior parietal cortex (somatosensory cortex)

Answer 6

Includes the postcentral gyrus and parietal operculum. Projects to the secondary somatosensory cortex (PE), which plays a role in tactile recognition and conduction of limb movements.

Question 7

Posterior parietal cortex

Answer 7

Responsible for higher-order visuospatial processing and motor control. It integrates visual, sensorimotor and auditory information, as well as attentional processes, and action control is the result of this integration. It is crucial for visuomotor guidance, spatial reasoning and mental manipulation, supporting tasks such as reaching, object manipulation, arithmetic, language comprehension and movement organization

Question 8

Secondary somatosensory cortex

Answer 8

Primarily receives input from the somatosensory cortex and projects to motor, premotor and supplementary motor areas. It is involved in somatosensory integration and conduction of limb movements.

Question 9

Angular gyrus

Answer 9

Integrates multimodal inputs, including visual, somatosensory, auditory and vestibular signals.

Question 10

Parietal reaching region (PRR)

Answer 10

Coordinates visually guided reaching and grasping. Neurons in the PRR encode the target of a movement rather than the specific details. The PRR is part of the parieto-mediotemporal pathway in the dorsal stream and supports visually guided movements during navigation

Question 11

Medial parietal region (MPR)

Answer 11

Includes areas ventral to the PRR and the posterior cingular cortex. It is involved in visually guided movements during navigation, route knowledge and control of body movements to specific locations. Neurons in the MPR respond in association with a specific movement at a specific location
