Fig. 1From: Age exacerbates microglial activation, oxidative stress, inflammatory and NOX2 gene expression, and delays functional recovery in a middle-aged rodent model of spinal cord injuryUninjured aged animals show altered stepping pattern in footprint analysis. a Uninjured 12-month-old rats (n = 10) have significantly wider toe spread than 3-month-old rats (n = 12). b Uninjured 12-month old-rats show a trend toward increased stride length compared to 3-month-old rats, supporting toe spread findings. ***p < 0.001.
