Letter to the Editors: in Defense of Visual Inspection

Abstract

Cornelissen and Haus (1) are certainly correct in their assertion that computerized data collection and analysis are useful and important tools in chronobiological research. We also agree that circadian rhythm data should be subjected to multiple complementary analyses whenever possible. In fact, both of our laboratories currently employ on-line collection of behavioural activity data, as well as several different computer-assisted statistical procedures, including analyses similar to those referred to by Cornelissen and Haus in their commentary.
