What memories are made of

Unraveling the differences between various kinds of memories depends on understanding changes that happen in the brain at the molecular level, says a professor at the University of Wisconsin-Milwaukee. To probe the exact role that genes and proteins play in the brain in response to experience, Fred Helmstetter compares fMRI in humans with gene expression in rats.

1. What emotional memories are made of
   10-04-2007 · EurekAlert!
   Both extensive psychological research and personal experiences confirm that events that happen during heightened states of emotion such as fear, anger and joy are far more memorable than less dramatic occurrences. In a report this week in Cell, Johns Hopkins researchers and their collaborators have identified the likely biological basis for this: a hormone released during emotional arousal "primes" nerve cells to remember events by increasing their chemical sensitivity at sites where nerves rewire to form new memory circuits.

   04-29-2007 · EurekAlert!
   Mice whose brains had lost a large number of neurons due to neurodegeneration regained long-term memories and the ability to learn after their surroundings were enriched with toys and other sensory stimuli, new studies have shown. The scientists were able to achieve the same results when they treated the mice with a specific type of drug that encourages neuronal growth. The studies suggest two promising avenues for treatments for neurodegenerative diseases such as Alzheimer's disease.

4. How emotionally charged events leave their mark on memory
   10-04-2007 · EurekAlert!
   Researchers have uncovered new evidence in mice that may explain how emotionally charged situations can leave such a powerful mark on our memories. Surges of the stress hormone norepinephrine (also known as noradrenaline) that often accompany strong emotions spark a series of molecular events that ultimately strengthen the connections between neurons, the team reports in the Oct. 5, 2007, issue of the journal Cell, a publication of Cell Press.

   04-30-2007 · EurekAlert!
   Sizeable literature has shown that as we grow into adulthood, our memory accuracy improves. However, psychologists Charles Brainerd and Valerie Reyna of Cornell University believe that adults may have less acurate memories than children under certain circumstances.

10. Blind people are 'serial memory' whizzes
    06-21-2007 · EurekAlert!
    Compared to people with normal vision, those who were blind at birth tend to have excellent memories. Now, a new study reported online on June 21st in the journal Current Biology, a publication of Cell Press, shows that blind individuals are particular whizzes when it comes to remembering things in the right order.
