1.2. Welcome To Your Brain

The brain is an amazing organ, capable of surprising memory feats, susceptible to damage, and yet remarkably adaptable to change.

While the human brain has a structure similar to that of other mammals, what makes it so very different is its size in relation to body size. Compared to the size of our bodies, human beings have much larger brains than other mammals.

In terms of weight, the average adult human brain weighs in at 1300 to 1400 grams or around 3 pounds. In terms of length, the average brain is around 15 centimeters long. For comparison, a newborn human baby’s brain weighs approximately 350 to 400 grams or three-quarters of a pound.

In women, parts of the Frontal Lobe and Limbic Cortex (areas associated with problem-solving and emotional regulation, tend to be bigger than those of men.

In men, the Parietal Cortex (associated with the perception of space) and amygdala (linked to social and sexual behavior) tend to be larger than those in women.

Made up of about 100 billion neurons and contributing nearly 2% of body-weight, your brain is the supreme structural and functional unit that controls and regulates you.

All parts of the human brain work in coordination with one another and execute a number of vital functions such as growth, maintenance, reproduction, sexual maturity, alarming/responding to environmental hazards and personal/behavioral developments.

Everything is grey matter with your brain.

There is no black and white here.

As you read A Smudgy Mind Guide you will learn there is no right or wrong answer.

Everything will always be smudged.
