Behavioral results − gait and NOR (Novel Object Recognition). (A) Paint pattern of paw prints during walking for the animal with a severe TBI at 6 HPI, note that the right back paw in green is dragging. (B) Novel object recognition test design and objects. The retention index indicates how much of the total investigation time was spent with the novel object. In the control and mildly injured animals, at all time-points after injury − the animal spent more than 50% of the time with the novel object. Note that in the severely injured animal at 1 DPI and 3 DPI, more time was spent with the original object (bars are less than 50%), which may indicate a memory impairment. The numbers above each marker indicate the total amount of time spent (s; seconds) investigating either object.
