How the Brain Remembers Right Place, Right Time

Hippocampal neurons create spatial and temporal “maps” of our world. Brain waves called “theta rhythms” help organize the activity of these neurons. A study by Bradley Lega, M.D., and colleagues determined how a group of neurons known as time cells allow the brain to correctly mark the order of events and assist in memory.

Two studies led by UT Southwestern researchers shed new light on how the brain encodes time and place into memories. The findings, published recently in PNAS and Science, not only add to the body of fundamental research on memory, but could eventually provide the basis for new treatments to combat memory loss from conditions such as traumatic brain injury, TBI, or Alzheimer’s disease.

About a decade ago, a group of neurons kno...
