It produces our every thought action memory feeling and experience of the world. This jelly-like mass of tissue weighing in at around 1.4 kilograms contains a staggering one hundred billion nerve cells or neurons. The complexity of the connectivity between these cells is mind-boggling.Each neuron can make contact with thousands or even tens of thousands of others via tiny structures called synapses. Our brains form a million new connections for every second of our lives. The pattern and strength of the connections is constantly changing and no two brains are alike. It is in these changing connections that memories are stored habits learned and personalities shaped by reinforcing certain patterns of brain activity and losing others.
