What Is the Capacity of Our Brain?

There is a persistent "information" published in the lay press that "we use only 10 % of our brain capacity".

Is this information true ? Where it was originated ? How do you measure "brain capacity" ?

There is an interesting consequence if this figure is true. We know that natural selection gradually leads to the atrophy of organs which are not used (e.g.: the tail, the appendix, or the third molar teeth). Therefore, if we are not using our full brain capacity (at least in 99.9 % of mankind), one would expect a decrease in the number of neurons.

I would like to know who has more information (or opinion) about this.
