Summary:
Researchers have found a way to pinpoint changes in brain activity that may underlie memory impairment, even before structural damage occurs. Dr. Scott Small and colleagues report in the December issue of Neuron that with a new high-resolution MRI technique, alterations in resting activity in subregions of the hippocampus, a brain circuit important for learning and memory.

Researchers have found a way to pinpoint changes in brain activity that may underlie memory impairment, even before structural damage occurs. Dr. Scott Small and colleagues report in the December issue of Neuron that with a new high-resolution MRI technique, alterations in resting activity in subregions of the hippocampus, a brain circuit important for learning and memory. By enabling researchers to detect activity changes in mice genetically altered to model age-related memory loss, the approach may further understanding of the mechanisms of the disease in humans.
