How is memory stored in the brain?

Is the brain a file storage cabinet, with individual information stored as a memory in each drawer? When something happens in our life, is it left in a specific place in the brain for later use? Neuroscience studies say that the process of storing memories in the brain is different. In fact, fragments of eventful memories, such as going to school first, are stored in the neurons of each part of the brain. As we try to remember, a complete picture emerges in the window of our minds as these isolated parts come together. However, the issue of memory is still elusive to neuroscientists. They are still working to unravel how the process of remembering works.

There are many neurons in the brain. These cells are connected to each other through connections called synapses. New synapses are created between different neurons as new memories are created in the brain. Communication between synapses is through certain chemical neurotransmitters. Imagine for a second you were transposed into the karmic driven world of Earl. You are very busy. At that time, a couple of short messages came from a little known person. You may avoid them. But what if you continue to receive hundreds of text messages from the same person?

Especially if the statement of this short message is the same? Then no matter how busy you are, start paying attention to the sender. Tell me, why are you sending me these short messages?

When nerve cells receive large amounts of the same neurotransmitter from a neighboring nerve, it communicates with the transmitting nerve. The power of communication alone determines how a memory is created. When the activity of synapses between different neurons is chronic, it is called long-term diversion in the language of neuroscience. Long-term diversification is well known among scientists working with memory. This process can change the strength of the synapse connection. Synapse connections need to be strong to create lasting memories.

The sender nerve repeatedly sends neurotransmitter signals to the recipient before long-term depolarization. At one stage of signal exchange several times in the same synapse, the recipient is stimulated to a greater extent even if the sender does not send additional neurotransmitters. The excited recipient nerve then begins to give electrochemical signals at high-voltage. This condition is called long-term diversification.

It’s a lot like building a good relationship with a semi-familiar sender of a text message. The sender does not have to send text messages at a higher rate. But the communication with him has become much easier and smoother. You might add the sender to your phone’s contact list to make further communication easier. Just as the brain makes strong connections to synapses through long-term diversion. Recalling specific memories will depend on the long-term connection of the synapses. Similarly, if you do not talk to the sender, the relationship between you will be even weaker.

To pick up a new tune on a guitar or other musical instrument, it has to be repeated over and over again. No matter how complicated the melody may seem at first, it becomes easier with regular practice. Once it can be played smoothly and quickly. What actually happens in the brain at this time? New synapses are created while learning. Regular repetition makes those nerve pathways smoother through long-term diversion. At one stage it became natural to play the melody alone. On the other hand, if the student refrains from regular melody practice for a while, the opposite happens. Inertia goes away, mistakes start to happen.

Human brain is a flexible organ. Here new synapses are constantly created and changed. On the other hand, it is like a muscle. If you do not exercise, the muscles become soft, the same can happen in the case of nerves. Just as we can easily create new memories, we need attention and repetition to make those memories last longer. Knowing the process by which the brain stores memory can help you become aware of the need to practice memory.
