Humans are social creatures who need others. In addition to being a human being is perfect because it has a sense of thoughts and feelings. Sense the thoughts and feelings we mutually sustaining because it could influence mood is going on. Sense thinking that distinguish us with animals and plants.
"WE THINK, WE ARE"
In
this world no one can live without thinking, because all the activities
that we're working on both conscious cognition process of occured or
not itself which is inseparable from our brains. The
brain is an organ of the body that play a role in any gestures or
actions that we are doing good in the form of sensory or motor activity.
Our brain is the most fantastic creation of God than any other creature. Our brain is composed by many of the neurons. Neurons have two effects: inhibitoris (preventing) and eksitatoris (stimulating). These neurons work (communicate) with the use of chemical substances called neurotransmitters. Neuron
transmitter that usher, causing chemical changes in neuron dendrites
message receivers, so the form of electrical signals. Neuron transmitter is called prasinaptik, and receiver neurons called pascasinaptik.
More than one hundred billion neurons in our brain. The
number of neurons in our brain has its own performance so that between
one neuron with other neurons have different functions.Neurotransmisi
speed between 0, 5 m/s to 120 m/s, unable to imagine how quickly the
neurotransmisi process to the extent that we don't realize that we are
in the process of cognition.
Amazingly, the God who has created the neurons in the brain that is so small and yet so complicated to understand. The system even more complex neurons compared to other systems in the universe that we think are already complicated really. But why there are neurons that so much but have different functions with a speed so fast??? If we think about it then, "my brain reeled when thinking about the brain" (my professor said).
Is God Almighty who knows all the creation that are so powerful and interesting for further investigation. For
it deserve tp grateful with all that is within our own bodies
because we have created the most perfect creature as compared to his
creation.
