The brain's deletion of memories before the age of 3 is a mysterious and complex process that scientists have not yet fully figured out. However, there are some theories that can explain this phenomenon.
To understand why the brain deletes memories before the age of 3, we need to know the process of memory formation and storage. Memories are achieved through connections between neurons, which form a complex network. In the early stages of development, neurons and connections in the brain are rapidly developing and remodeling, forming new neural circuits. This process is known as synaptic remodeling.
Before the age of 3, the baby's brain is at a stage of high development and Xi. Due to the remodeling of neurons and connections, at this stage, the brain focuses on receiving and processing new information and experiences. This means that earlier memories are overwritten and replaced by new memories in order to accommodate new Xi and cognitive needs. This is also the reason why most people cannot recall memories before the age of 3.
Another possible explanation is that memories before the age of 3 may not have been properly verbally expressed and encoded. Language is an important tool for us to think and express our memory, but before the age of 3, children's language skills are not perfect. They may not be able to accurately describe and express early memories, so these memories may be considered "lost."
While the brain's deletion of memories before the age of 3 remains an unsolved mystery, this process may be related to brain development and the need for Xi. We should cherish the current memories and experiences that make up our unique personal identity and life experiences.
But everyone's childhood is full of exploration, Xi and growth. At this stage, we begin to learn about the world, feel the warmth of family and society, build relationships, and experience many interesting things. Whether it's intimate moments with family, playing with friends, visiting new places, or Xi learning new skills, these are all precious memories of childhood that have a profound impact on our growth and development.
