Memory is so fundamental to human behavior that any impairment to it can severely impact our daily life.
Did it ever happen that you forgot the name of the person you just met? How do we remember some stuffs for decades and some fade after a few moments? What actually is that makes the difference between long-lasting memories and volatile ones?
After several tests on mouse, Caltech researchers have finally discovered that the strong memories are results of the synchronized "teams of neurons" that provide redundancy to retain memories over long time. The team of researchers developed a test to study mice's neural activity as their brain resembles that of human in many ways. The result showed that more the quantity of neurons, longer will the memory last.
For years, people believe that practicing an action more, brings better chance to remember it later as the conventional theories about human memory storage say that making a memory more stable requires the strengthening of the connections to an individual neuron.
But we now think that this is likely because practicing an action time and again, increases the number of neurons encoding the action. The latest results suggest that increasing the quantity of neurons that encode certain memory enables it to persist for longer period of time. The statement, "Unity is Strength" has again been justified.😄
