Brain holds secret memory system, study finds

Your brain may possess greater abilities than you realise. The Massachusetts Institute of Technology conducted a study which discovered that adult brains contain millions of silent synapses which stay dormant yet exist to create new memories at appropriate times.

The study discovered that approximately 30% of brain cortex synapses stay dormant yet maintain the ability to activate when required. The research discovery changed scientists' understanding about how humans develop learning abilities and remember information throughout their lives.

Scientists maintained their belief that silent synapses only existed during early development for several decades. The new findings challenge that idea, showing the adult brain keeps a large запас of these connections on standby.

The research shows that the synapses enable the brain to create new memories while maintaining its current memory store. The system establishes an automatic mechanism which enables users to learn new material while maintaining their existing knowledge.

The brain contains trillions of synapses which continuously adapt their structure to store new experiences. The process of changing existing connections creates a danger which may result in the loss of existing memories. The research indicates that the brain prefers to use silent synapses when it needs to avoid changing its established connections.

The synapses need essential receptors for signal transmission because their absence keeps them inactive in normal situations. The system achieves complete functionality after it receives all required components, which allows it to store new information efficiently.

The team made the discovery while studying dendrites using a technique called eMAP, which expands brain tissue for high-resolution analysis.

Neuroscience department MIT Mark Harnett conducted research which showed that scientists discovered multiple filopodia structures which connect to silent synapses throughout the adult human brain. The researchers discovered these structures in greater numbers than they had originally estimated.

Silent synapses, which scientists discovered in the adult brain, provide evidence that silent synapses enable humans to learn new information while retaining their existing memories. The study shows how declining flexible connections with age restricts learning abilities through time.

Researchers believe that studying silent synapse function will create opportunities to develop therapeutic solutions for memory disorders.
