There are elements involved when it comes to storing memory, namely – chemicals and electricity. Nerve cells are connected to other cells, with the meeting point known as a synapse. When actions are played out, they occur within this interconnected wiring, carrying electrical impulses between the cells. Neurotransmitters which are chemical-based elements, are sent off as a part of the electrical pulse that cover areas between cells, spreading the same to cells present in the surrounding area. Dendrites receive these electrical impulses, which connect themselves to other cells like a mesh, thus spreading the information uniformly.
The memory chamber branches out into various sections, where different areas that we focus on in our lives are determined by how often we do them, or how unexpectedly they occur. For example, driving a car or working out a routine on how you start your day, is all packed into a memory niche that is permanent and unchanging. Routine is usually stored away as concrete information, because we play these acts on a regular basis. Things like education can be recollected later, depending on how we stored the information that was learned, although unless we repeatedly touch upon it, this can be lost and remembered in bits and pieces only. Things like music are also short-term where repetitive exposure to the same determines how we store the information. Practicing a skill, or undergoing training in a field is what keeps our brains constantly tuned in to the same sources, therefore making our synapses stronger when recognizably similar signals are repeatedly sent through the cells.
Therefore higher the frequency of information entering the brain cells, stronger is the connection that is formed. As new information is fed into our brains, new connections are brought to life, where the brain has its way of grouping and filing away all these incoming data. This is how the brain forms memories, where exterior factors like training, practice and regular exposure, determine how we perfect them. Researchers have also pinpointed that how we pay attention to the information that is presented to us, is a huge role player. The more attention is paid to detail, the higher the chances of recording the minutest fragments of a memory. Read entire article.
