Final answer:
The signals in the parietal cortex and hippocampus are responsible for processing spatial information and memory.
Step-by-step explanation:
The signals in the parietal cortex and hippocampus play an important role in processing spatial information and memory. In the parietal cortex, these signals help determine the location of objects in space and their relation to the body. The hippocampus, on the other hand, is involved in forming and retrieving memories.
For example, if you were in a room and wanted to reach for a book on a shelf, the signals in the parietal cortex would help you determine the location of the book in relation to your body, while the hippocampus would be responsible for remembering where the book is on the shelf.
