Mammals brains are relatively large for their body size, and they have lots of folds, or convolutions. This produces lots of surface area to support complex nerve networks.
Also, only mammals have a neocortex, the six-layer structure is responsible for higher information processing.
The convolutions increase the surface area of the cerebrum. Surface area is important for physiological functions in general as it provides a greater surface for exchange or transport (such as that of potassium, sodium, and water).
{Based upon that most important of all of the Physical and Chemical principles that affect and have effects on every element of Life} Surface area.
They increase the surface area.
The convolutions increase the surface are of the cerebrum.
convolutions or gyri
a human brain has a larger cerebrum a humans brain has more convolutions they both have the same parts(spinal cord,cerebrum,and cerebellum)
The "squiggly" appearance of the brain refers to the sulci and gyri the comprise the cerebral cortex. The sulci are the valleys, or sunken portions, and the gyri are the raised portions. The "squiggly" convolutions of the cerebrum (brain) allow for more surface area. Thus, the contours of the brain help increase the overall volume of the brain inside its limited space, the cranium.

It is also 90% water.

I think the sheep cerebrum has less Yes, the sheep cerebrum does have less of the convolutions and sulci, because the human cerebrum has evolved mental capacity over time.
Sulci
The answer is sulcus.
The convolutions increase the surface are of the cerebrum.
convolutions or gyri
The convolutions of the cerebrum. The margins of which are separated by the lateral cerebral fissure.
surface area
The convolutions in the cerebrum increase surface area
I don't know that this is 100% accurate, and I'm not sure the exact number, but I am pretty sure that there are less convolutions and sulci of the sheep cerebrum than the human cerebrum. I agree with the person above, the convolutions and sulci of the sheep cerebrum are less than the human cerebrum, because the humans have evolved more mental capacity.
Your cerebrum is an important part of your brain. How's that?
