Ramachandran and Rogers-RamachandranArticle describe their experience and views of phantom limbs. Perceptual qualia, brain maps, and current concepts of neural pattern coding vs place coding are described to understand how neural activity leads to conscious experience. Our body image may indeed be a purely transitory internal construct.
CliffordArticle provides a concise review of the biological issues related to memory and cognitive loss in patients with human immunodeficiency virus (HIV) infection. Current effective therapy is reviewed and the approach is highly useful for the clinician.
Hart and colleaguesArticle describe a large randomized series of trials to evaluate the preventive effect of aspirin on stroke. They find that people with major risk factors for vascular disease may be intermediate between a substantial decrease in risk for those with manifest vascular disease and a possible small increase for healthy people due to a risk-accentuated intracranial hemorrhage. Choosing aspirin with these parameters in mind to prevent stroke needs to be carefully considered. These and other issues are put into critical perspective in a clear and compelling way in an editorial by Barnett and ElisziwArticle.
