The mysterious protein that shows how we create memories

Remembering exactly changes brain structures. That's because learning and remembering are the result of the ruthless change of synapses in the brain.

The long-term changes involved in this process are encrypted in the so-called RNA that has been created in brain neurons, the basic blocks of the central nervous system.

The RNA is transported from the nucleus of neurons to the certain synapses, where it does its job.

An earlier study showed that the building protein of RNA “Staufen2” plays a key role in the transport of RNAs sent to their destinations. However, the effect this has on learning has been understood recently.

A new study published in “Genome Biology” has shed new light on the matter.

Researchers used rats to test the effects of reduced “levels Standen2” in memory.

After limiting “quantity limit Stiffen2” in the mouse's brain, they submitted to behavioral tests that revealed a visible negative effect on their memory.

The Rats were given a variety of tasks, such as finding their way through a maze they had previously visited.

Mice with “Stiffen2” reduced were much slower, then leaving the control group, showing an effect on their work memory.

“generally, long-term memory continues to work, and rats remain able to learn how to find a food source, for example,” explained one of the researchers Michael Kiebler.

But when mutants are asked to remember what they have learned after longer periods of time, their performance is evidently worse than in wild animals”, he added./Periscopi/
