According to the latest international study, with age learning is getting harder due to reduced ability filter out old memories. In the hippocampus of the head the brain contains a “switch” consisting of NR2A subunits and NR2B – NMDA – a receptor that optimizes memory and learning. NR2B is found in large quantities in children, which allows neurons work a little longer and form stronger bonds or synapses. After puberty, this ratio changes and more NR2A is produced. “When you are young, your brain is capable of consolidate some ties and weaken others to acquire new ones memories, said study co-author Dr. Joe Z. Jian of Georgia Regents University in a press release. – If only yours synapses become more stable, then you never get rid of disturbing or unnecessary information, and this becomes a problem. ” Jiang’s team studied genetically modified mice with the predominance of NR2A and a smaller number of NR2B, i.e., with the same ratio of subunits, as in an adult. Mice still have strong synapses and short-term memories formed, but their the ability to model information was lower; animals were less able to weaken synapses and develop new long-term memories. “Unusual is the ability to weaken existing connections, “said Jian. Such changes in the brain an adult can contribute to the occurrence of phenomena often observed in older people who may get lost in paths, as well as in adults who cannot get rid of their emphasis on learning a new language. “We know we are losing ability to speak excellent foreign language if we we study this language after puberty, – explained Jian. – I can learn English, but from my Chinese emphasis is very difficult to get rid of. The question is why. “Results studies were published in Scientific Reports on January 8th. Casey ryan
