Our BRAIN,, bring / collect information from our sensory organs & send them to a centralized location or we can also say the Central Nervous System to perform / generate a unified / purposeful action.. The ‘N’ numbers of thin fibres / muscles in our BRAIN worked together to perform complex activities.. In centralized location this unprocessed / scattered information processes & our BRAIN extracts the useful part..

After then,, past experiences & current needs are combined together to generate the best possible results(s) through Motor Neurons..  These activities require simultaneous activities done by various parts / muscles..

Information about sound & light,, atmosphere,, temperature,, position,, orientation & so on are preloaded in our BRAIN.. other creatures have different other abilities also like birds senses the magnetic field of Earth to find their path,, reptiles senses the heat through infrared to find their food or to identify the danger..

Each sensory organ have specialized receiving cells.. These cells receive / gather raw information & send it to the Central Nervous System in our BRAIN..
