They were the same size.
If you mean "How much percentage of water does a human brain have?", the answer is about 77-78%.
The depth of the fissure creating the cerebral hemisphere in a human brain is larger than that of a sheep. This is due to the fact that the human brain is larger and rounder compared to the elongated brain of the sheep.
You need to narrow down what you're looking for, either the size of a human brain, or a Neanderthal brain, The Homo sapien (us) have evolved from the Homo Neanderthal to the point where we can be classified as sub species but going on gut instinct here, This should help you out Neandertals 1200-1750 1450 modern Homo sapiens 900-1880 1345 http://anthro.palomar.edu/homo2/mod_homo_2.htm --- Additional There is a school of thought that puts the Neanderthal as a sub species of the genus Pleistocene and a parallel evolution not a predecessor to homo-sapian.

The Neanderthal's brain was the same size as a modern human's brain.
The same as a modern human.
The Neanderthal brain was the same size as modern human.
The difference between Neanderthal DNA and human DNA is less than one percent.
evolution has given homo sapein (modern man) the biggest brain out of all the other species of human we are in most cases the only humans that live on this planet yet.
Their brain size was the same as a modern human.
They are not really that different. The human brain is simply larger and more complex - but fundamentally they are the same.
a human brain has a larger cerebrum a humans brain has more convolutions they both have the same parts(spinal cord,cerebrum,and cerebellum)
Neanderthal was an ancient human, closely related to modern humans.
