![]() The process also works in reverse, with the baby mice able to form more stable memories after the scientists used genetic engineering and drugs to hinder neurogenesis. Amazingly, this triggered an infant amnesia response in the adult mice. The team then placed the adult mice on a wheel to stimulate hippocampal neurogenesis, aka the formation of new neurons in the brain. However, while the fear endured in adult mice the babies began to lose their sense of distress after one day. Unsurprisingly, both sets of mice experienced a fear response when placed back in the cages. In a simple yet telling experiment, a team of researchers placed adult and baby mice in cages and administered mild electric shocks. While the speed of the learning process is incredible, it could also be its demise. They use these complex neural pathways to absorb information, with the brain forming up to 1000 new synaptic connections per second. Information overloadĪt birth, the brain of a baby contains roughly 86 billion neurons. Today, researchers are continuing to unravel the mysteries of early childhood memories and shed new insight on the human experience. The phenomenon is known as “childhood amnesia" and was first coined by Sigmund Freud. While the early years of life are arguably the most formative, research suggests that childhood memories begin to fade at the age of seven. ![]() ![]() Every person has a unique collection of memories, yet little is known about why some linger, some fade away and others are lost altogether. Sometimes they can spark a feelgood glow and other times they can trigger extreme reactions like post traumatic stress disorder. ![]()
