As neurons are lost during aging:
A)an equivalent level of functioning is lost
B)new neurons develop to replace them
C)an even greater level of functioning than that represented by the neurons is lost
D)the brain compensates by better using remaining neurons

Question

Quizplus · Accepted Answer

The brain compensates by better using remaining neurons to maintain overall functioning despite the loss of neurons. While new neurons can develop in certain regions of the brain, particularly in the hippocampus, this process decreases with age and is not sufficient to fully replace the loss of neurons in other areas. Additionally, because neurons are specialized cells, the loss of a specific type of neuron can result in a loss of a particular function, but it is not necessarily an even greater level of functioning than that represented by the neurons as a whole.
