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.

Convolutions of the brain provide increased what?
The convolutions increase the surface are of the cerebrum.
The surface of the cerebrum is folded into elevations that resemble speed bumps are called what?
convolutions or gyri
How is the sheep's brain similar and different from a human's brain?
a human brain has a larger cerebrum a humans brain has more convolutions they both have the same parts(spinal cord,cerebrum,and cerebellum)
Why is the human brain squiggly?
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.
What portion of the brain is largest?
Frontal lobe
The convolutions on the cerebrum's surface is called?
Convolutions on the cerebrum surface is called
Convolutions seen in the cerebrum important because they increase what?
{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.
How do the convolutions and sulci of the sheep cerebrum compare with the human cerebrum in number?
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.
What are the valleys separating the convolutions on the surface of the cerebrum?
Sulci
What are the depressions between the convolutions of the cerebrum?
The answer is sulcus.
Convolutions of the brain provide increased what?
The convolutions increase the surface are of the cerebrum.
The surface of the cerebrum is folded into elevations that resemble speed bumps are called what?
convolutions or gyri
What is parietal operculum region of the brain?
The convolutions of the cerebrum. The margins of which are separated by the lateral cerebral fissure.
The convolusions seen in the cerebrum are important because they increase the?
surface area
What are the convolutions of the brain?
The convolutions in the cerebrum increase surface area
How does colliculus in sheep compare to human?
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.
How do you put cerebrum in a sentence?
Your cerebrum is an important part of your brain. How's that?
