Measuring Flow Velocity and Flow Direction by Spatial and Temporal Analysis of Flow Fluctuations [PDF]

open access: yesThe Journal of Neuroscience, 2008
If exposed to bulk water flow, fish lateral line afferents respond only to flow fluctuations (AC) and not to the steady (DC) component of the flow. Consequently, a single lateral line afferent can encode neither bulk flow direction nor velocity. It is possible, however, for a fish to obtain bulk flow information using multiple afferents that respond ...
