Charting space representation in the brain of freely swimming goldfish
Professor Ronen Segev uses Deuteron Technologies’ 16-channel aquatic logger (MS7) to chart space representation in goldfish. Much of our understanding of navigation comes from studying mammals in controlled lab environments. The simpler brain structures of goldfish, however, provide an opportunity to discover the fundamental principles of navigation. Mapping how space is represented in the goldfish brain can help us understand how basic building blocks of spatial coding are ultimately integrated to support navigational abilities.
For Professor Segev’s description of his electrophysiological recording technique using Deuteron Technologies’ aquatic logger combined with a water-compatible implant that allows for adjusting the recording location by microdrive-controlled tetrodes, see this paper:
