The Electroretinogram of the Horseshoe Crab, Limulus polyphemus: A Laboratory Exercise in Sensory Physiology

The eye of the horseshoe crab, Limulus polyphemus represents an easily-excised and durable preparation for investigating various parameters of a typical sensory system. One can study the time course of dark adaptation as well as the dependence of response amplitude and latency on stimulus intensity in both the dark-adapted and light-adapted eye. Requirements for specialized, technical equipment are minimal. Suitable for undergraduates in advanced general biology, physiology, and special projects.
