title: Insulin treatment affects the behaviour of Tetrahymena pyriformis and T. malaccensis.
abstract: Populations of Tetrahymena pyriformis and T. malaccensis were treated with insulin, then washed and treated again 24 h later. The ethograms of controls, treated, washed and retreated populations were drawn. Statistical analysis showed that T. pyriformis was affected by insulin more severely than T. malaccensis. In T. pyriformis the effects of the 'memory' of the first treatment seem to be more relevant than those of the first and second treatments themselves. On the contrary in T. malaccensis treatments with insulin per se seem to affect the behaviour more strongly than the memory of the first treatment itself. These results are discussed in detail in the context of previous work.
