Brain and Nervous System: How do the instructions go hand in hand?
Have you ever thought of brain's instructions? If you start off with at one point, you will go somewhere else hammering the research behind it. Scientists and researchers have been digging into this matter for ages.
As far as the neuroscientists are concerned, “Brain” and “Nervous System” are completely made up of a unit cell known as "NEURON." Billions of Neuron cells send signals from one to another; that is what we are doing in daily activities. In other words, what is being done, it is done by the sets of instructions executed by "Neuron." Dendrite and Axon, two elements of Neuron, send signals same as circuits and make movements responsible for actions. In addition, electrical and chemical signals are important for sending and receiving signals through a communicative path (a bridge between two Neurons) which is called "Synapse."
Different parts of the human brain materialize signals to do specific tasks. Furthermore, some parts of the brain are responsible for making someone read, write, speech delivery, and express thinking abilities. Neurons keep sending signals until the job is done. However, in any stage of this process, if the decision is changed for any reason, suddenly, Neurons stop sending signals and execute the new decision. For example, when you see a mosquito and hit it with your hands. How long does it take? It is very quick, isn't it? The whole process is usually done in just a few seconds, even before you realize it.
It is very common for us to think about all the actions of what are happening in our daily life. We think, but often we do not make our way out to find the story behind it.
