What happens in Alzheimer's disease when the hippocampus experiences altered neurogenesis and brain functioning declines?
A) Individuals experience a disruption in messages sent from one neuron to the other, resulting in confusion and disorientation.
B) The generation and development of new neurons is impaired, resulting in no new neurons replacing those that have died.
C) The prefrontal cortex compensates for loss of neuronal activity in the hippocampus, resulting in no loss in problem-solving but a greater decline in memory functioning.
D) Individuals experience interference in muscle movement, resulting in jerky, uncontrollable movements.

Altered neurogenesis in the hippocampus means that the generation and development of new neurons is impaired, which leads to no new neurons replacing those that have died. This results in the decline of brain functioning and is a hallmark feature of Alzheimer's disease.
