BRAIN MAP WORKSHEET
Teacher Answer Sheet (cont’d.)
3. A. Map B represents the brain of an elderly person engaged in challenging mental
activity. Mentally active people develop more dendrite branchings, and, thus make
more interconnections to serve as pathways for messages.
B. MAP A represents the brain of an elderly person who is not involved in as much
mental activity. There are less dendrite branchings to make connections. Less roads
represent less pathways for messsages
4. Examples of mental activity will vary. As students age, they should respond with
examples of mental activity throughout their life.
5. Examples of physical activity will vary. As students age, they should indicate exercise
is still important at any age. Intensity and type of exercise may depend on many factors
such as other health problems or mobility.
6. A brain map similar to map B may indicate an elderly person who may have alternate
ways of solving a problem since there are several routes to arrive at the same
point. This map has many roads or dendrite connections. Map A shows less roads or
alternate pathways to arrive at the same point. Brain map A could represent an
elderly person who has less ways to solve a problem.
7. Examples of events which could create blockages in neural pathways could be brain
injury or a dementia such as Alzheimer’s disease. (Dementias are discussed in
lesson 6.)
8. Staying in school provides an opportunity to provide experiences to promote mental
and physical activities to maintain a healthy brain.
