Giant Brain Candy: A Petabyte-Scale Memory?. One famous estimate puts the brain’s storage near 2.5 petabytes — about 3 million hours of TV. It’s a rough calculation, but it hints at how vast memory may be. Source: Estimating memory capacity.

Giant Brain Candy: 86 Billion Neurons. Your brain holds about 86 billion neurons. Scientists counted them by dissolving brain tissue into a ‘soup’ of cell nuclei and tallying samples of it. Source: Counting the brain’s cells.
Giant Brain Candy: The Other 85 Billion. Neurons have partners: about 85 billion other cells, mostly glia — astrocytes, oligodendrocytes and microglia. The old claim of ten glia for every neuron turned out to be a myth. Source: Neurons and glia, counted.
Giant Brain Candy: A 20-Watt Supercomputer. Your brain runs on about 20 watts, roughly a dim light bulb. It is only 2% of your body weight, yet it uses about 20% of your body’s energy. Source: The brain’s energy budget.
