FAQ 7: Is it acceptable to change disector height among groups or within groups? I am unsure about whether or not to maintain the height of my disector across tissue specimens that vary in thickness?

The parameters must be constant within a subject, and almost always are kept constant within a group. The disector height is one of these parameters. The one parameter that will be allowed to change within an animal/region is section height (section thickness). This should be measured with a frequency to account for variance in the section thickness.
