Long-term memory mechanism identifiedRSS Feed
Researchers have identified an important element in long-term memory, which could potentially aid the treatment of brain injury, which often affects memory.
A study, published in the Journal of Neuroscience, demonstrated a chemical influx into a set of neurons seen in the fruit fly, which is key to the workings of long-term memory.
Authors said that the increase in calcium influx was also seen in other animal models, making it likely that a similar mechanism occurs in humans.
Study leader Ron Davis said: "We observed an increase in calcium influx into a specific set of brain neurons in normal fruit flies that was absent in 26 different mutants known to impair long-term memory.
"This logical conclusion is that this increase, which we call a memory trace, is a signature component of long-term memory."
