How Brain Works

Brain is part of the nervous system, that connects to the spinal cord, which in turns connect to all other organs. And vice versa. It is made up of trillions of neurons (nerve cells) separated from each other and connected together with synapses (chemical signals that carry electricity).

Nervous system governs all other biological systems in the body, all other systems influence the nervous system.

Sensations

Sensation is a non-negotiable element of the nervous system.

For example some of the sensory receptors are:

• Neurons in the eye perceive certain colour of light and direction of movement.
• Neurons in the skin perceive particular type of touch, like firm touch, soft touch etc
• Neurons in the ear perceive certain sound.

Human's can't sense infrared rays, magnetic fields etc without any technology.

Perceptions

Perception is the ability to take the sensation and focus on it and make sense of it.

You can multi-task and focus your attention on two different things at the same time. Either by dilating or concentrating your spotlight of attention or focus.

You can do things in two ways:

• Deliberate: Top-down, high effort.
