We still know very little about how our brain works. We don’t know how we think. We don’t know how we analyze and solve problems. We don’t know how we remember. We don’t even know why we forget.
Let’s consider the question of memory.
It is estimated that we have a hundred, or so, billion nerve cells (neurons) in our brain and that each neuron is connected to several thousand other neurons, giving a total of about a hundred trillion possible neuronal connections (synapses). It is believed that memory is stored in neuronal circuits that are formed by long-lasting synaptic connections.
