Chapter 40, Problem 14TYK

Summary Introduction

To review:

The demonstration of altered activity of the genes in the brain of a mouse as a result of aging.

Introduction:

The aging process affects the brain in many ways, like brain shrinkage, due to reduction in its molecular weight, development of dementia, and change in the neuron connections. Old people tend to forget things due to changed brain wirings. These studies are well established in mouse models, in which the gene activity that alters the brain function can be observed easily.
