Question

Quizplus · Accepted Answer

The CRUNCH model suggests that the older brain uses more of the same processes it used in the past, as well as supplementary processes, to compensate for any decline in function. This means that the brain may rely on additional neural networks or alternative strategies to perform tasks, rather than simply increasing synapses or using memory aids. Brain training exercises and recruiting friends can also be helpful, but they are not the two main mechanisms suggested by the CRUNCH model.
