This study further investigates the possible connection between postconcussive cognitive impairment and damage to forebrain cholinergic innervation. Moderate parasagittal fluid percussion injury was delivered to adult male rats. Water maze performance and synaptosomal choline uptake was measured at various times following injury. Water maze learning was(More)
Traumatic brain injury is well known to cause deficits in learning and memory, which typically improve with time. Animal studies with fluid percussion or controlled cortical impact injury have identified transient disturbances in forebrain cholinergic innervation which may contribute to such cognitive problems. This study examines the extent to which water(More)
Clinically, elderly patients have a higher cognitive morbidity from head trauma than young patients. We have modeled injury in aged rats in an effort to elucidate the pathophysiology of this enhanced sensitivity and, in particular, to determine if there are susceptibility differences in forebrain cholinergic innervation in young versus aged rats. Aged(More)
