What is pachygyria?
* (medicine) A malformation of the brain characterized by its being too broad in form.* Unusually thick convolutions of the cerebral cortexAbove retrieved from Answers.comViper1
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.
The surface of the cerebrum is folded into elevations that resemble speed bumps are called what?
convolutions or gyri
What is the difference between a gyrus and sulcus?
a sulcus is a depression or a groove found on the surface of an organ or tissue,as on the surface of the brain separating adjacent convultion. While a gyrus is one of the prominent rounded elevations between the sulci or grooves on the surface of the hemispheres of the brain.
What role do convolutions play in the brain?
They provide more surface arean for nerves and such.
What is polygyria of the brain?
polygyria - a brain with an excessive amount of convolutions
What are the convolutions of the brain?
The convolutions in the cerebrum increase surface area
What is the more convolutions that are found in the brain of an animal?
the less healthy the brain
What is the brain convolution?
A Brain Convultion is a another name for Seizures of epilepsy. A brain Convulsion usually happens when a peron who caught epilepsy always swim withno guard ,oftens watching tv, aand climbing mountains. * * * * * The above answer refers to convulsions, not convolutions! Brain convolutions are the wrinkles on its surface.
What is the definitions of convolutions and sulci?
convolutions: a form or part that is folded or coiled; one of the convex folds of the surface of the brain.Sulci: a shallow groove, such as that between gyri on the brain surface.
What do you call the folds that can be found in the brain?
The folds on the surface of the brain are called 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.
What increases the surface area of the brain?
The convolutions in the brain increase surface area. In simpler words, those lines and ridges in the brain are what increases the surface area.
What are the difference between human brain and the sheep brain?
The human brain is larger. The positioning of the hind brain is different, due to the erect position of humans. Convolutions are increased in humans (increases surface area). The sheep's brain has a smaller cerebellum (lesser motor control/less complex learned motor behaviors). There is a larger pineal gland in sheep (related to circadian rhythms/seasonal reproduction).
A sentence with convolution?
the convolutions on Ken's brain were damaged when his head went through the windshield of Malibu Barbie's car
Why does the brain have the gyri?
The human brain , through evolution, has increased the number of foldings (gyri) in order to increase the actual surface available to support the neurons within it. Similar to the branching "tree" structure of the alveoli in the lungs, the number of neurons able to be contained and supported by the "white matter" is vastly increased by the presence of these convolutions.
