Abstract
Mazes are broadly used to investigate animal decision-making and spatial learning. However, they have been sparsely employed to explore C. elegans behavior and training-improved performance. This protocol describes a highly reproducible, low-cost maze platform, made of the standard, agar-based, nematode culturing material. It can be used to reliably assess C. elegans' maze behavior, and we have recently applied this protocol to establish multisensory learning. Limitations include challenges in locomotion tracking and in distinguishing learning formation versus retrieval. For complete details on the use and execution of this protocol, please refer to Gourgou et al. (2021).
