Heat acclimation provides sustained improvement in functional recovery and attenuates apoptosis after traumatic brain injury.

Heat acclimation (HA) offers functional neuroprotection in mice after traumatic brain injury (TBI). This study further characterizes endogenous neuroprotection acquired by HA (34+/-1 degrees C, 30 d) after TBI. We establish here the ability of HA to induce sustained functional benefits and to reduce activation of apoptotic pathways.
