Brain
The center of our nervous system and daily thoughts, the brain is a complex, magnificent organ. Ask questions about parts of the brain and their functions here.

What is the largest and second largest part of your brain?
The biggest part of the brain is the cerebrum. The cerebrum makes up 85% of the brain's weight.
The cerebrum is the thinking part of the brain and it controls your voluntary muscles - the ones that move when you want them to.
The cerebellum is a motor region of the brain, dealing with the subconscious movements of the muscles. This butterfly-shaped section is the second largest area of the brain. The cerebellum deals with coordination, posture, and balance.
What will cause traumatic brain injury?
concussion
firearms
Traumatic Brain Injury (also know as TBI) occurs when a person experiences blunt force trauma to the head. This could occur secondary to an accident (i.e. motor vehicle accident) or a fall. This could also occur from a strike to the head, either intentionally or unintentionally (i.e. altercation, or sports related head injury). The TBI occurs when the brain is jostled within the "shell" of the cranium, or bone that houses the brain. This jostling can injure the brain, perhaps causing bleeding or swelling. The injury can range from minor to extremely serious, even causing death. Patients that experience even a minor TBI can have lifelong affects, depending on the areas of the brain impacted and the overall seriousness of the injury.
What happens when your brain is split?
Cutting apart the two hemispheres of the human brain is a drastic step, and it is one of the most controversial operations ever performed. Yet it can succeed, when all else fails, in relieving violent, drug-resistant epileptic seizures.
Can your brain fall out your ear?
I am prytty shure it would happen, but mabey not (be dead for 2000 yrs. to see)
Does one part of the brain completely take over when another part is damaged?
The brain is plastic but usually not in the way that is described in the question. A damaged part of the brain remains damaged and healthy parts of the brain usually cannot completely take on the duties of the damaged part since it has its own duties to take care of. However when a body part is damaged (e.g. a person's eyes are blinded by external means), the part of the brain that is usually responsible for processing information from that body part can be repurposed to perform another, though still similar, action (e.g. the vision cortex of the blinded person will be repurposed to process hearing information).
What parts of the brain will be working when you reach for something and pick it up?
I thought it was the frontal lobe, parietal lobe, and cerebellum.
What links all parts of the nervous system to the CNS?
The ralpehripe nervous system connects the brain and spinal cord to other body parts.
your brain is pink because of the blood flowing through it.
Brain matter is actually light or dark grey. What makes it pink is the blood that supplies your brain with oxygen and nutrients.
What part of the brain controls the muscular system?
The cerebellum functions to control the skeletal muscles. It is also involved in some cognitive functions such as attention and language, and in regulating fear and pleasure responses.
the motor cortex
What are the protective layers around the brain and spinal cord?
Pia Mater, Subarachnoid Space, Arachnoid Mater, Dura Mater, Crainum/Vertebral Bodies.
You can touch your brain, except not by yourself. There are ways.
Is the medulla oblongata part of the limbic system?
The medulla oblongata is not part of the limbic system. If grouped, it is usually considered part of the brain stem. It is extremely crucial for survival as it controls the autonomic centers (involuntary things) like breathing, the heart, and the digestive organs.
What activities are controlled by the cerebellum?
The biggest part of the brain is the cerebrum. The cerebrum makes up 85% of the brain's weight, and it's easy to see why. The cerebrum is the thinking part of the brain and it controls your voluntary muscles - the ones that move when you want them to. So you can't dance - or kick a soccer ball - without your cerebrum.
When you're thinking hard, you're using your cerebrum. You need it to solve math problems, figure out a video game, and draw a picture. Your memory lives in the cerebrum - both short-term memory (what you ate for dinner last night) and long-term memory (the name of that roller-coaster you rode on two summers ago). The cerebrum also helps you reason, like when you figure out that you'd better do your homework now because your mom is taking you to a movie later.
The cerebrum has two halves, with one on either side of the head. Some scientists think that the right half helps you think about abstract things like music, colors, and shapes. The left half is said to be more analytical, helping you with math, logic, and speech. Scientists do know for sure that the right half of the cerebrum controls the left side of your body, and the left half controls the right side
The cerebellum is the second largest part of the brain. It controls muscle coordination, maintains normal muscle tone and posture, and coordinates balance. So if you riding a bike or a skateboard, and hitting a baseball your using your cerebellum because cerebellum sends messages to the cerebrum that directs and coordinates the activity. Its also controls voluntary movement and maintains posture and balance by controlling muscle tone... I only add some important details about how cerebellum works =)
There are many different types of brain injury, depending upon the severity of the force upon the head, as well as which portion of the brain is affected. To simplify, brain injuries can be classified as traumatic or acquired, with additional types under each heading. All brain injuries are described as either mild, moderate, or severe. Traumatic brain injury is a result of an external force to the brain that results in a change to cognitive, physical, or emotional functioning. The impairments can be temporary or permanent.
An acquired brain injury is an injury to the brain that is not hereditary, congenital, degenerative, or the result of birth trauma. Acquired brain injury generally affects cells throughout the entire brain.

How the messages travel to and from the brain?
If you're thinking about telepathy or something similar, you don't need it to send a message to other brain.
Yes.
How long can a zombie live with out a brain?
If a zombie looses its head in an insta shot it could live about 2 or 3 seconds after it looses it head. If it took another shot then it will die immeditaly
What does the smell of September smell like?
August spells like spring except there's a mix of leaves
What do shrooms do to the brain?
The main compounds bond in your brain in the same way that serotonin does. So you hallucinate and feel good. It also cases a rise in dopamine levels. Most trips last no more than 8 hours and there is some "after glow" effect of feeling good and brightness of colors for the next 24 hours or so. There are no studies that show any long turn effects, though the change in brain chemistry and the fact that long term use will cause the effect of you needing to take more and more to gain the same high could indicate that there is a change in monoamine oxidase in the brain. This could theoretically lead to a depression state as the monoamine oxidase is responsible for balancing serotonin levels.
Olfactory bulb sheep brain vs human brain?
olfactory bulbs larger in sheep like the rat we dissected as well because of the need for heightened sense of smell for food, predators etc. these defense and survival mechanisms are more needed in sheep than humans.
