Olfactory behavior of swimming C. elegans analyzed by measuring motile responses to temporal variations of odorants.

abstract：:Extraretinal information, such as corollary discharge (CD), is hypothesized to help compensate for saccade-induced visual input disruptions. However, support for this hypothesis is largely for one-dimensional transsaccadic visual changes, with little comprehensive information on the spatial characteristics. Here we sy...
