About Brain

Nerve cells, called neurons, are the fundamental elements of the central nervous system. The central nervous system is made up of about 100 billion neurons (10 to the power 11). The brain grows at an amazing rate during development. At times during brain development, 250,000 neurons are added every minute.

At birth, almost all the neurons that the brain will ever have are present. The first three years of life are a period of incredible growth in all areas of a baby’s development.

A newborn’s brain is about 25 percent of its approximate adult weight. But by age 3, it has grown dramatically by producing billions of cells and hundreds of trillions of connections, or synapses, between these cells. Parents should grab the chance of the first years to help their children get off to a good start and establish personalized patterns for life-long learning.

Brain Structure

The brain can be considered the most complex organ in human body and the centerpiece of your nervous system. Although a human brain works as a unified whole, neuroscientists can identify areas within it that perform specific functions. The brain is organized into three interconnected layers: the central core, limbic system, and cerebral cortex, all of which contain structures that regulate everyday life.

The central core helps regulate basic life processes, including breathing, pulse, arousal, movement, balance, sleep, and the early stage of processing sensory information. The limbic system mediates motivated behaviors, emotional states, and memory processes. It also regulates body temperature, blood pressure, blood sugar level, and other housekeeping activities. The cerebral cortex directs the brain’s higher cognitive and emotional functions. It is divided into two almost symmetrical halves called cerebral hemispheres. Each hemisphere contains four lobes:
1.) Frontal Lobe
2.) Occipital Lobe
3.) Parietal Lobe
4.) Temporal Lobe
These lobes oversee all forms of conscious experience, including perception, emotion, thought and planning.

What is brain dominance?

According to the theory of left-brain or right-brain dominance, each side of the brain controls different types of thinking. Additionally, people are said to prefer one type of thinking over the other. For example, a person who is "left-brained" is often said to be more logical, analytical and objective, while a person who is "right-brained" is said to be more intuitive, thoughtful and subjective.

The Right Brain

According to the left-brain, right-brain dominance theory, the right side of the brain is best at expressive and creative tasks.
Some of the abilities that are popularly associated with the right side of the brain include :

• Recognizing faces
• Expressing emotions
• Music
• Reading emotions
• Color
• Images
• Intuition

The Left Brain

The left-side of the brain is considered to be adept at tasks that involve logic, language and analytical thinking.
The left-brain is often described as being better at:

• Language
• Logic
• Critical thinking
• Numbers
• Reasoning
