Working Principle - Deepstash

Working Principle

The brain sends and receives chemical and electrical signals throughout the body. Different signals control different processes, and your brain interprets each. Some make you feel tired, for example, while others make you feel pain.

Some messages are kept within the brain, while others are relayed through the spine and across the body’s vast network of nerves to distant extremities. To do this, the central nervous system relies on billions of neurons (nerve cells).

Brain

The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS.

About Consciousness

Consciousness is everything you experience - taste, pain, love, feeling. Where these experiences come from is a mystery.

Many modern analytic philosophers of mind either deny the existence of consciousness, or they argue that they can never be meaningfully studied by science.

The nervous system
  • It is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body's electrical wiring.
  • Structurally, the nervous system has two components: the central nervous system (the brain, spinal cord, and nerves) and the peripheral nervous system (sensory neurons, ganglia and nerves that connect to one another and to the central nervous system).
  • Functionally, the nervous system has two main subdivisions: the somatic, or voluntary, component (nerves that connect to one another and to the central nervous system and the autonomic nervous system (regulates certain body processes, such as blood pressure and the rate of breathing, that work without conscious effort).
