This article describes about how does the nerve system processes information and how does it create a response. This is very important as the information helps to understand how we take care of all the load of inputs of information.
The most basic yet most important function of the nervous system is to process complete incoming information. This helps the brain to general proper mental and motor responses which are further conveyed to the body to create signals for the body as a response. Nearly 99% of the sensory responses sent to the brain are ignored. These are considered as irrelevant and unimportant. Senses like clothing, seating pressure, unimportant noise are not paid much attention. Objects that are in the field of vision may catch more attention but yet the brain is intelligent in negating things.
Out of all the unnecesary things, those signals that are prominent are passed on to the motor and pre motor areas of the brain. Desired responses are thus created. This function of the brain to pass on information, challenging and processing of information is called as the integrative function of the nervous system.
This is where the synapses come into picture. A motor response thus generated is needed to be sent from Neuron to Neuron. The synapse have 2 kinds of signals. The signals which pass on the response are called as facilitatory signals while others are called inhibitory signals. Depending on the signals, the response is passed on from synapse to synapse. Through the selective function the main response traverses further through the nerve system.
