Kurama: The average brain has around 100 billion brain cells (neurons) - that’s 100,000,000,000 brain cells (although this is a ‘guesstimate’ based upon other factors ).
Each neuron is functionally connected to around 1000 neurons (again, a guesstimate). If we assume that neurons have either an ‘on’ or ‘off’ state (digital logic - although, not unsuprisingly, we have reason to believe that brain storage uses analogue voltage ‘levels’ rather than digital logic for storage) we can then assume that each neuron can ‘read or write’ 1000 neurons - essentially 1000 bits or 0.122 kilobytes of data.
Assuming that this ‘data’ ripples through the brain in a steady-state manner, we can assume that the average amount of ’storage capacity’ is hence 100,000,000,000 by 0.122 kilobytes, or 122 million (122,000,000) kilobytes. If we convert that figure to gigabytes, we arrive at the sum of 116.34 Gigabytes of data in digital terms.
Obviously there is a massive fudge factor here - the calculations make alot of very ‘broad’ assumptions - it’s really just a ‘fun’ measure of what our brain capacity would be if it was a digital system.

What I recall reading is that the brain does not store information in neurons, it stores in in the synapses between neurons, using chemical voltage levels acoss the synaptic gap; this is crucial because neurons cannot be replaced normally, but there is no real limit to the number of synapses that a neuron can form or deform between itself and other neurons.
