Canadian scientists discovered that the reason we struggle to recall memories from our early childhood is due to high levels of neuron production during the first years of life. The formation of new brain cells increases the capacity for learning but also clears the mind of old memories. The findings were presented to the Canadian Association of Neuroscience.
Neurogenesis or the formation of new neurons in the hippocampus, a region of the brain known to be important for learning and remembering, reaches its peak before and after birth. It then declines steadily during childhood and adulthood.
Scientists wanted to find out how the process of new neuron generation impacted on memory storage. They carried out their research on younger and older mice in the lab.
