The human brain is probably the most intriguing part of the complex human anatomy. The coordination of the different parts of the body is the result of the smooth functioning of the various 'regions' of the brain. The position, size and most importantly, the functionality of each region, in a way, defines its importance. Though, no region can actually be called the 'most important'. The human brain gets excited or reacts to external stimuli. Our reactions to the inherent feelings of fear, awe and elatedness 'excites' the brain, resulting in reactions that are strongly identified with.
The working of the brain is the collective functioning of neurons that are separated by a gap called synapse. When a neuron 'communicates' with another neuron, what it dopes is release chemicals known as neuro-transmitters. These neuro-transmitters travel across the gap or synapse, to the next neuron. In this way, the neurotransmitters stimulate each other towards the resultant 'action'. All this happens very fast and results in starting muscular activities, creating memories, recalling facts and reacting to danger. In fact, anything the brain controls requires these electrical impulses that travel between the neurons. This consistent flow of the impulses and the resultant reactions are what we externally read as excitement.
