Cognitive rehabilitation has been shown to have beneficial effects on functional recovery following traumatic brain injury. In the present study, the rehabilitative effects of cognitive training in the T-maze on functional recovery of behavior and cortical sparing following a cortical impact injury (CCI) were examined. T-maze alternation has a widespread application in detecting cognitive dysfunction, and alternation in particular utilizes working memory. 47 male Sprague-Dawley rats were divided into six groups (sham trained, sham yoked, sham control, injured trained, injured yoked, injured control). Injured animals received a bilateral frontal craniotomy (1.0 A/P, 0.0 M/L from Bregma). The cortices were depressed at a depth of 2.5 mm at a velocity of 3 m/s. T-maze training began on post surgery day 2 and continued daily through post surgery day 19. Following this rehabilitative T-maze training, cognition was assessed using two different memory tasks in the Morris water maze (MWM).
