In the present study, we examined cell survival within several BF nuclei in rodents following transient middle cerebral artery occlusion. We tested the hypothesis that a previously established neuroprotective therapy\u2014resveratrol preconditioning\u2014would rescue BF cell loss, deficits in cholinergic-related memory performance, and hippocampal synaptic dysfunction after focal cerebral ischemia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Adult (2\u20133-month old) male Sprague-Dawley rats or wild-type C57Bl\/6J mice were injected intraperitoneally with a single dose of resveratrol or vehicle and subjected to transient middle cerebral artery occlusion using the intraluminal suture method 2 days later.
