Why We Forget

Why We Forget.
Science shows our memory can easily be distorted and erased, but our forgetfulness also helps us survive.
Our memories are wrong at least as often as they are right. At best, they are incomplete, though we might swear other wise. This affects countless aspects of our lives, and in many cases our memories — true or false — affect others’ lives.
Perhaps the most exciting neuroscience discovery of the last several decades is that our brains are not static hunks of tissue but flexible and adaptive organs that change throughout our lives. The term used to describe this new understanding is brain plasticity. The flexibility of your brain is essential to memory and indispensable to learning. Specifically, the “plastic” parts of our brain are synapses — the connection points that allow neurons to transmit signals between each other.
