Gotta Walk before you run.......

The human brain is one of the most extraordinary organ in a multi-cellular organism especially in us humans. It forms the center of the nervous system in humans. The brain is made up of 80-120 billion neurons (maybe even more) i.e nerve cells. The nerve cells in the brain are mostly coated with myelin sheath, which allows the impulses to travel much more quickly.
For centuries, scientists and philosophers have been fascinated by the brain, but until recently they viewed the brain as nearly incomprehensible. Now, however, the brain is beginning to relinquish its secrets.
The brain is like a committee of experts. All the parts of the brain work together, but each part has its own special properties. The brain can be divided into three basic units: the fore-brain, the mid-brain, and the hind-brain.
The hind-brain includes the upper part of the spinal cord, the brain stem, and a wrinkled ball of tissue called the cerebellum. The hind-brain controls the body’s vital functions such as respiration and heart rate. The cerebellum coordinates movement and is involved in learned rote movements.
The uppermost part of the brain stem is the mid-brain, which controls some reflex actions and is part of the circuit involved in the control of eye movements and other voluntary movements
The fore-brain is the largest and most highly developed part of the human brain: it consists primarily of the cerebrum and the structures hidden beneath it.

Here are two basic videos on the human brain which helps you to grasp things easily.
