How do the relative sizes of the sheep and human?

Compare the relative sizes of the sheep and human cerebral hemispheres. The cerebral hemisphere of the human is larger than the sheep. The human brain has more contours than a sheep’s brain because the human brain has a larger surface area and the more sulci and gyri will allow the brain to increase in surface area.

How do the gyri and sulci of the sheep cerebrum compare with the human cerebrum in numbers? The human brain has more contours than a sheep’s brain because the human brain has a larger surface area and the more sulci and gyri will allow the brain to increase in surface area.

One may also ask, why are the olfactory bulbs larger in sheep than humans? The olfactory bulb, on the contrary, is comparatively larger in the sheep’s brain when compared to the human brain, because animals usually rely more upon their senses and abilities of smell than humans do.

The human brain is relatively large and very wrinkled. Wrinkles increase the surface are for neurons. A folded brain surface has a greater surface area — which means a greater power for processing information, but it’s not entirely clear what factors determine the iconic shape of gyri and sulci in the human brain.

Which hemisphere of the brain controls vision?

Through the optic chiasm, the visual signals from the left hemifields of both eyes are sent to the right hemisphere of the brain, while the signals from the right hemifields of both eyes are sent to the left hemisphere of the brain.
