The neurological and cognitive function of TBI rats was improved after HBO therapy. (a) mNSS scores were lower after HBO treatment than TBI group at 3, 7, and 10 days. (b) In the locomotor navigation test, the escape latency shortened significantly with HBO treatment on days 3, 7, and 10. (c) In the exploration test, the number of platform crossings was higher after HBO treatment than TBI group on 3, 7, and 10 days. Values are expressed as mean ± SEM (n = 8/group). ^***P < 0.001, ^**P < 0.01, ^*P < 0.05 vs. TBI group. HBO, hyperbaric oxygen; mNSS, modified neurological severity score; TBI, traumatic brain injury.
