Older Brains Get Too Full for New Information

According to new research, learning becomes more difficult as we get older because our brains get too full for new information. This may be due, in part, to finding that with advanced age we get less sleep during the stage in which we don’t dream. Both studies are reported in the prestigious Nature family of journals.

Cellular Mechanisms of Long Term Memory Storage

Dr. Menahem Segal, head of the Laboratory of Neuronal Plasticity at the Weizmann Institute of Science in Israel, studies the neuronal basis of long term memory in the brain. Of particular interest are conditions that are associated with deterioration of memory systems, such as those occurring in Alzheimer’s disease patients and mentally retarded children.
