Why is the human brain so special?
Neuroscientists have become used to a number of “facts” about the human brain: It has 100 billion neurons and 10- to 50-fold more glial cells; it is the largest-than-expected for its body among primates and mammals in general, and therefore the most cognitively able; it consumes an outstanding 20% of the total body …
Is human brain powerful?
It is so complex that it is capable of generating the highest level of consciousness and the mental processes by which we perceive, act, learn, and remember. Those 86 billion neurons power all of our thoughts, perceptions, memories, and our emotions—all products of our brains.

Does Brain Size Matter? Obviously, not all people have the same size brain. Some are larger, and some are smaller. You might find yourself wondering if brain size might be linked to characteristics such as disability or intelligence.
How many GB does the human brain have?
You might have only a few gigabytes of storage space, similar to the space in an iPod or a USB flash drive. Yet neurons combine so that each one helps with many memories at a time, exponentially increasing the brain’s memory storage capacity to something closer to around 2.5 petabytes (or a million gigabytes).
