The procedure and results of the experiment are briefly explained in easy words right in the beginning of the article so that readers get maximum information in the first few seconds of reading. The editors have written how the mice that had been bred to be more exercise-loving over generations (high voluntary wheel-running) had a 13% larger volume of the midbrain. A 3D reconstruction of the brain of a mouse is also presented alongside the article to provide the readers with a visual idea of the location and size of the midbrain of a regular mouse.
The author has also incorporated the comments of the professors involved in the research project to make the article more interesting and additional information is also provided to the reader along with the personal opinion of the experts. They have quoted professor Garland saying that it is the first study which has shown a particular mammalian behavior resulting “in a change in the size of a specific brain region” (Science Daily).
As the reader goes further, the author has provided more important details of the experiment such as the selection of the mice which has been going on for 65 generation in the lab (20 years), and the functioning of different parts of the brain. This section of the article answers any questions that might have occurred in the mind of the reader and deals and deals with them one at a time. From the sample selection to the procedure adopted by the researchers to reach conclusions, the briefly explains them all in easy language. Other findings of the research are also mentioned toward the end of the article including how the high voluntary wheel-running mice also had a larger volume of non-cerebellar brain mass.
The article also mentions what the researchers wanted to achieve through these experiments and whether or not they have been successful. In order to provide a concise answer to these questions, they have provided yet another direct quotation of the
