Unlocking the Mystery of Memory

Recommended for you

Synapses are gaps between brain cells that enable chemical and electrical messages to be transmitted. Sections of the brain tissue were engineered to emit light, enabling scientists to see individual synapses in colour. Distinct types of molecules in each synapse were tagged by colour, allowing detection of complex patterns across the brain.

Different groups of synapses were active depending on the behaviours of the mice - such as feeding, running and jumping. Scientists believe the diversity of synapse types may be key to recalling information, helping the brain to quickly locate memories through patterns of its activity. Researchers found this molecular map was altered in mice bred to mirror aspects of autism and schizophrenia, because they did not recall information properly.

This finding could help provide new insight on brain diseases. The study was funded by the European Research Council and Wellcome, and is published in the journal 'Neuron'.

Anyone who has braved the last-minute dash around the shops on Christmas Eve will know that the term 'festive madness' wasn't coined out of thin air. Everyone has an image of how Christmas is supposed to be.

It's drilled into us from movies like White Christmas, to festive holiday cards: Christmas is about fun, family, love and joy! And yet, for many families, it's the opposite. Christmas is about turmoil, If, for whatever reason, they haven't Brain map could unlock the mystery of memories Stock picture.

Due to this bread-lion you run through the door and slam it behind you, but as you look up, you notice a rather large orangutan on the ceiling. Scientists have found that recalling journeys such as these, along with other memory devices, can improve the brain connectivity in those that have never tried it before. In their study, neural connections began to resemble those of a world champion after as little as six weeks training 2. You may not be a world memory champion just yet, but a little practice could go a long way — at least with your weekly shop anyway.
