It’s capable of surprising feats of memory and learning.
It’s susceptible to damage, and yet remarkably adaptable to change.
Considering all of its many capabilities, you may begin to wonder, how big is the human brain?

For the sperm whale, the brain is only about 0.06% of body weight.
A newborn baby’s brain weighs approximatelythree-quarters of a pound(350 to 400 grams).
The brain is considered fully formed at age 25.
Men tend to have bigger brains than women.
Researchers currently estimate that there are around 86 billionneurons in the human brain.
Does Brain Size Matter?
All humans do not have the same size brain.
Does that mean that highlyintelligentpeople have bigger brains?
In some cases, there might be a link.
Researchers have found brain size can be linked to certain diseases or developmental conditions.
Autistic children tend to have bigger brains (and earlier disproportionate brain growth) than non-autistic children.
It depends on who you ask.
However, not all researchers agree with McDaniel’s conclusions.
It is also important to note that variations in brain size between humans are relatively small.
