---4--- Neurobiology & Human Anatomy & Physiology.
The human brain is the most complicated object that we know of. Even if we simplify each neuron (complex eukaryotic cells themselves), we still end up with approx. 100 billion neurons interconnected by approx. 100 trillion synapses. With these complex intricate structures comes incredible functions. Apart from the nervous system itself, every other organ system (in (almost) every animal), closely interacts with the nervous system. The brain is a means for the universe to know itself. It is a product of the laws of physics and natural selection. All our emotions, memories, feelings, thoughts, and actions, are simulated by the trillions of physicochemical interactions that comprise the functions of our sensory, cognitive and motor systems.
