Final answer:
A cross section of the brain with generalized atrophy shows significant neurodegeneration, especially in the ventricles and hippocampus. This can be observed in conditions like Alzheimer's disease, where the brain shrinks and loses brain cells.
Step-by-step explanation:
A cross section of the brain with generalized atrophy would show significant neurodegeneration, particularly within the ventricles and hippocampus. In Alzheimer's disease, for example, the brain exhibits dramatic shrinkage and loss of brain cells. This can be seen in brain images where the affected brain appears much smaller and shows reduced metabolic activity compared to a healthy brain.
