Symbolic cue-driven activity in superior colliculus neurons in a peripheral visual choice task.

abstract：:Visual input provides vital information for helping us modify our walking pattern. For example, artificial optic flow can drive changes in step length during locomotion and may also be useful for augmenting locomotor training for individuals with gait asymmetries. Here we asked whether optic flow could modify the acqu...
