PHOTOS memories, capture an image with the neural mechanism that is repeated all times that our brain stores data and puts it in a database memory: Scientists have managed the Montreal Neurological Institute and Hospital in tandem with colleagues from McGill University and the University of California at Los Angeles. They captured the moment in which makes the translation mechanism of the protein responsible for the formation of long-term memory. This is the first such experiment carried out successfully, and is the visible proof of the fact that every time a memory that forms new proteins are produced in the synapse, the structure that enables communication between neurons. This mechanism increases the strength of synaptic connections and strengthens memory. The study, published in the journal Science, is fundamental to understanding how to create paths of memory and the ability to monitor in real time will understand in detail how the memories are born. According to the scientists behind the characteristics of human memory are two: stability and flexibility. The first is fundamental to keep the information in time and the second allows the brain to learn and adapt to reality. And 'why the research focused on synapses, headquarters for the exchange and storage of data in the brain. These structures form a very wide network of connections and on the move: the ability of our nervous system to modify the operating efficiency of these connections between neurons and establish a new rule out other fact is that synaptic plasticity. This property allows change the system to function and structure in the long term and dependent on events that affect it, as, of course, experience. For this reason, the synaptic plasticity is the property that is the neurobiological basis of the phenomenon of memory and learning.

"But if this network is constantly changing, as are fixed then the memories, how they are formed? An important phase in the formation of long-term ones, you know, is the translation, or the production of new proteins in the synapse, going to strengthen the connection mechanism and at the same time the memory, but no one had ever translated into images that process - Wayne Sossin says neuroscientist, co-author of the study - It 's here that we began: the detector using a translation, or a fluorescent protein that can be easily intercepted and tracked, we see an increase in local protein synthesis during formation of a memory. The most interesting thing is that this translation is closely related to the mechanism of synapse needs to be accomplished and the activation of post-synaptic cell: this shows the need for cooperation between the two moments that make up the synapse, the pre-and post, and then a connection between the two parts of the neurons in this process meet. And 'this activity that we photographed. "The discovery made by Sossin and his research team will serve to improve understanding of the processes that underlie the formation of our memories and will be useful, the scientists point out, for the development of therapies to correct the problems of loss or memory impairment, from normal aging to more complex neuronal degenerative diseases.
