It possesses about 100 billion neurons with roughly 1 quadrillion (1 million billion) connections known as synapses wiring these cells together. Combined, it has a memory capacity of approximately 2.5 petabytes (or 2.5 million gigabytes). To put that in perspective, it took the 4th most powerful supercomputer (82,944 processors) in the world, 40 minutes to complete a simulation of one second of human brain activity.
