1. Using a traditional maze set-up we are exploring memory acquisition and consolidation with a focus on behavioral and molecular determinants, multisensory integration (electrosense, vision, lateral line, touch), and development.
2. Environmental factors affecting locomotor behavior and electric organ discharge activity (e.g. endocrine disruptors, electromagnetic radiation)
3. The role of vision in weakly electric fish

Specific Topics:

• Maze learning in Gnathonemus petersii: molecular bases of memory acquisition and consolidation & the role select electric organ discharge patterns play as spatial rehearsal tools
• Can electric organ discharge patterns serve in spatial memory transfer?
• Environmental effects on electric signaling in electric fish
• Development of spatial learning in Mormyrus rume (we breed this species and will test their locomotor and electric behaviors at various developmental stages)
• Development of contrast vision in Mormyrus rume
