Virtual treasure hunt shows brain maps time sequence of memories

People have little difficulty remembering the chronology of events, determining how much time passed between two events, and which one occurred first. Apparently, memories of events in the brain are linked when they occur closely together.

What makes memories stronger?

A team of scientists at NeuroElectronics Research Flanders reports that highly demanding and rewarding experiences result in stronger memories. By studying navigation in rats, the researchers traced back the mechanism behind this selective memory enhancement to so-called replay processes in the hippocampus, the memory-processing center of the brain. These important findings provide new insights into one of the most enigmatic […]
