Os experimentos demonstram um método fácil para que os estudantes ganham experiência em examinar a estrutura muscular, respostas sináptica, os efeitos de gradientes de íons e permeabilidade em potenciais de membrana. Além disso, um sensório-motoras CNS-músculo-circuito é apresentado para mostrar um meio para testar os efeitos de compostos em um circuito neuronal.
