There are various ways we know what a certain part of the brain does one way is to study what abilities people loose after they have an injury to a part of the brain another is to use fmri scans to see which parts of the brain are most active when a person does a certain task. The frog is among a handful of small animal species that serve as laboratory specimens for hands-on learning the placement and structure of the frog's internal organs are very similar to humans', though of course more simplistic, making them a suitable tool for teaching internal anatomy the frog. The frog could thus be an interesting model in which to examine the mechanisms of dopamine failure in early anoxia, which occurs rapidly in the mammal but over a period of hours in the `slow death' of the anoxic frog brain.
