Our cerebrum is covered by the cerebral cortex. The cerebral cortex has many crevasses, which increases the surface area. This is largely the reason our brains are able to contain billions of neurons!

The surface area of the cerebrum is increased by the presence of convolutions called gyri and grooves called sulci. These features allow for a larger surface area within the limited space of the skull, providing more space for neurons and increasing cognitive abilities.

Why its good to have a wrinkled brain?
Having a "wrinkled" brain, which means having lots of folds and creases on the brain's surface, is good because it increases surface area for more neurons and connections. This can enhance brain functioning and cognitive abilities, enabling faster thinking and better problem-solving skills.
What are the folds on the cerebral hemispheres?
The folds on the cerebral hemispheres are called gyri, which are the raised ridges on the brain's surface. The grooves separating the gyri are called sulci. These folds increase the surface area of the brain, allowing for more neurons and connections to be packed into a smaller space.
What is the approximate total surface area of the cerebral cortex?
The approximate total surface area of the cerebral cortex is around 2,500 square centimeters in adults.
Name three main parts of the human brain?
The three main areas of the brain are the cerebrum, cerebellum, and the medulla oblongata.The most largest and prominent area is the cerebrum, which is responsible for consciousness. It is found at the front of the brain and the outer layer of it is the cerebral cortex. It divides into two halves and each half is divided into four lobes: frontal, parietal, temporal, and occipital.Note: the two halves of the brain can communicate with each other through the corpus callosum.The second largest portion of the brain is the cerebellum. It has a bi-lobed, butterfly-shaped structure and works to coordinate muscle movement in order to have smooth and graceful actions. Also, it is responsible for maintaining normal muscle tone and posture by receiving information from the inner ear; therefore, keeps or restores balance.The third area of the brain is the medulla oblongata, which is close to the spinal cord. It contains centres for heartbeat, breathing, blood pressure and reflex centres for vomiting, coughing, sneezing, hiccupping and swallowing.
How did Paul Broca contribute to psychology?
Paul Broca is primarily known for his work in neuropsychology, particularly in the area of language localization in the brain. He discovered the region of the brain now known as Broca's area, which is responsible for speech production. His research provided important insights into the relationship between brain function and behavior.
What increases the surface area of the cerebrum?
The surface of the brain has wrinkles. The sulci are the inner folds of the surface of the cerebrum, and the gyri are the "bumps" of the surface. These increase the surface area of the cerebrum.
What increases the surface of the cerebrum?
The surface of the brain has wrinkles. The sulci are the inner folds of the surface of the cerebrum, and the gyri are the "bumps" of the surface. These increase the surface area of the cerebrum.
What increases the surface area of the cerebral?
The cerebrum has many folds or wrinkles which increases the surface without increasing the volume
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.
Convolutions of the brain provide increased what?
The convolutions increase the surface are of the cerebrum.
What increases the surface area of this part of the brain?
The folds in the brain increase the surface area. It nearly triples the surface area. As we grow, more of these bends form.
Where in the brain is taste?
In the insula of the cerebrum area of the brain
What is the large area of the brain?
cerebrum
Largest area of the brain?
The cerebral cortex, which is the outer layer of the brain, is the largest area of the brain in terms of surface area and plays a key role in higher brain functions such as thinking, planning, and processing sensory information.
What area of the brain is in control of consciousness?
cerebrum
What is the largest area of the brain and how many hemispheres does it have?
cerebrum ...
What increases the cerebrum's surface area?
This only applies to larger mammals. The cerebral cortex is folded into many gyri (ridges) and sulci (furrows), which has allowed the cortex to expand in surface area without taking up much greater volume.
