Question 1

Distinguish between frontal lobe neglect and parietal lobe neglect.

Accepted Answer

Frontal lobe damage can result in neglect, though it is less common. The brain region typically involved is area 6 or the premotor cortex. Symptoms tend to be directed only to the region related to grasping space, whereas parietal lobe neglect extends to distance space.

Question 2

How do the results of the Corbetta et al. study shed light on the finding that patients with right - posterior parietotemporal lesions show more pronounced contralateral neglect than do patients with left - hemisphere lesions?

Accepted Answer

The Corbetta study investigated shifts of attention and the regions that could potentially serve this demanding task. It was compared with a fixed attention task. Results from this study highlight the superior role of the right parietal cortex in governing attentional processing, regardless of the visual field presentation (left or right visual field).

Use the following to answer questions:
Based on work by Maurizio Corbetta, match the following processes with the corresponding region of brain activation.
-attention to color

Accepted Answer
