Single areas of the brain don't operate in a vacuum. They connect to others in complicated neural networks, so that you can put different information together. So, don't limit yourself to words.
A quick doodle or diagram can capture connotation in a more visual way or summarize a concept that would take a paragraph to write out. Symbols also can indicate stress or importance, drawing attention to specific ideas. Even leaving a space between data sets can have meaning and keep you organized.
Also consider using a color code. Use a color scheme when noting information. This offers easy visual organization, which lets you find specific information quickly when you need it.
