Brown research reveals key insight into memory-making
...meanings. Scientists believe that certain forms of mental
retardation and diseases such as Alzheimer's are linked to nerve cell dysfunction in the hippocampus. The new research provides new targets for drugs or other treatments for these conditions. Esther Penick and Jeffrey Edwards, postdoctoral research f...
