 **Data description:**
 
-Calcium fluorescence signals of hundreds of simultaneously imaged neurons in mouse retrosplenial cortex during a virtual navigation task (running on a linear treadmill track with head-fixed), from different experimental groups of animals: control mice, mice with unilateral hippocampus lesion (uni), and mice with bilateral hippocampus lesions (bi).
+Calcium fluorescence signals of hundreds of simultaneously imaged neurons in mouse retrosplenial cortex during a locomotion task (running on a linear treadmill track with head-fixed), from different experimental groups of animals: control mice, mice with unilateral hippocampus lesion (uni), and mice with bilateral hippocampus lesions (bi).
 
 Each element in the .mat cell array corresponds to data from one animal with the suffix indicating experimental group (n = 5 mice in each group).
