Brain Volume

The human brain is the center of thought, emotion, and behavior. Our brain is composed of many different parts that are used to process thoughts, make decisions, and carry out essential bodily functions. Brain volume, which is also referred to as brain mass, is the total amount of space taken up by the brain. This is typically measured in milliliters (mL) or cubic centimeters (cm3). Brain volume can vary greatly from person to person and is determined by a variety of factors, including genetics, lifestyle, diet, and age. In general, those with higher levels of brain volume typically indicate higher intelligence levels. One study found that a specific gene known as “brain derived neurotrophic factor,” or BDNF, was positively associated with higher levels of brain volume. Notably, this gene has also been linked to higher levels of intelligence. Overall, the average brain volume is estimated to be around 1,350 mL for a male and 1,200 mL for a female. However, this can vary widely depending on age and lifestyle factors. Generally, those with more physical activity and who are a normal body weight tend to have larger brains than those who are more sedentary and/or overweight. Additionally, research suggests that as we age, our brain volume tends to decrease. The declines are especially noticeable in individuals who experience memory problems and dementia. In Summary, brain volume is the amount of space taken up by the brain and is typically measured in milliliters (mL) or cubic centimeters (cm3). Factors such as genetics, lifestyle, diet, and age may all influence an individual’s brain volume. Generally, those with higher levels of brain volume indicate higher intelligence levels. In addition, as people age, their brain volume tends to decrease, especially in those with memory problems.
