I'm trying to find this too. A 2mm is small and a 20mm is large, but I have a 12mm brain cyst and cannot find how serious it may be and if it's causing my multitude of neurological symptoms.

What size is considered large for a cortical cyst?
cortical cyst is very common. In most cases, they are not serious and even cause no symptoms if the cysts are less than 3-5 cm. When the cyst exceeds 5 cm in diameter, it is large and need to be followed by urltrasound, CT scan or MRI.
What if your brain is the size of a large grapefruit?
I don't see what you are asking by asking 'What if....' The human brain is certainly about the size of a large grapefruit.
What are the large bundle of nerves caled extending from the brain through the spinal column?
The large bundle of nerves extending from the brain through the spinal column is called the spinal cord. The spinal cord connects the brain to the rest of the body.
A brain cell contains thousands of mitochondria What can you infer from this information about the brain's need for energy?
From this, one can infer that the brain needs a large quantity of energy on a regular basis.

What is an invaginating arachnoid cyst?
AddedPrevious answer is good...Can occur anywhere between surface of the inner brain 'cover' to arising in the spinal cord; like all cysts they are fluid-filled 'bubbles/balloons" that usually --but not always-- put pressure on the brain or spinal cord and cause worsening/permanent nerve damage. There are basically two different types of subarachnoid cysts: either present at birth, and sometimes demonstrate neurological symptoms before the age of 20 years old... Or can be as a result of brain trauma... Not all of these cysts require surgical intervention... just those causing symptoms.With todays minimally invasive "microsurgical" techniques, neurosurgeons are really a lot more successful in removing the "sac" that must be removed to prevent the recurrence of the cyst.Refer to the website: http://www.ninds.nih.gov/disorders/arachnoid_cysts/arachnoid_cysts.htm for a complete review of what you should know about this disease process...GordonAnswerArachnoid Cysts Arachnoid cysts are cerebrospinal fluid-filled sacs that may develop between the surface of the brain and the cranial base or on the arachnoid membrane--one of the 3 membranes that cover the brain and the spinal cord.Most cases begin during infancy, however onset may be delayed until adolescence. Symptoms of an arachnoid cyst are related to the cyst size and location. Small cysts are usually asymptomatic and are discovered only incidentally. Large cysts may cause cranial deformation or macrocephaly (enlargement of the head), producing such symptoms as headaches, seizures, hydrocephalus (excessive accumulation of cerebrospinal fluid), increased intracranial pressure, developmental delay, and behavioral changes. Other symptoms may include hemiparesis (weakness or paralysis on one side of the body) and ataxia (lack of muscle control).Arachnoid cysts most often occur in males.Is there any treatment?Treatment for arachnoid cysts is symptomatic. When symptoms warrant, the surgical placement of a shunt may be required to decompress (remove pressure from) the cyst.What is the prognosis?Untreated, arachnoid cysts may cause permanent severe neurological damage due to the progressive expansion of the cyst(s) or hemorrhage (bleeding). With treatment most individuals with arachnoid cysts do well.
What are the large brain?
The "large brain" would be considered the cerebrum which contains the cerebral cortex as well as some sub-cortical structures.
What is a cystic lesion on the brain?

Where does the cerebrospinal fluid circulates?

A Freaking Forimina (Lushka and Magendie) Say Back Away! Weird, yes. Memorable? Most definitely.
Is fish really brain food?
Fish is considered brain food because it contains a large amount of highly unsaturated fatty acids, which are good for your brain.
What is the function of the layers of the meninges?
-Protect the central nervous system -Responsible for nourshing the brain -Provides cushioning effect for the CNS -Support the large venous channels carrying blood from the brain toward the heart
What is the difference between meninges of the spinal cord and the brain?
The dura mater in the brain is fused to the periosteum vs in the spinal cord the epidural space is in between the dura mater and the intervertebral canal.Three fibrous membranes that surround the brain and spinal cord to protect the central nervous system. The pia mater, a very thin membrane, adheres to the surface of the brain and spinal cord. The subarachnoid space, containing cerebrospinal fluid, separates the pia mater from a second membrane, the arachnoid. Around the brain, fine filaments connect these two membranes, which are believed to be impermeable to fluid. The third membrane, the dura mater, is strong, thick, and dense. It envelops the arachnoid, covers the inside of the skull, and surrounds and supports the large venous channels carrying blood from the brain. Several septa divide it and support different parts of the brain. In the spine, the dura mater and the arachnoid mater are separated by the subdural space; the arachnoid and pia mater are separated by the subarachnoid space. The extradural space (between the dura mater and the wall of the vertebral canal) is the site of epidural anesthesia (see anesthesiology).
What is the treatment of microphthalmia?
Large cysts causing microphthalmia should be aspirated or removed surgically.

When is a person considered to be megalencephalic?
In general, a brain that weighs more than 1600 grams (about 3.5 pounds) is considered megalencephalic. The heaviest brain on record weighed 2850 grams (about 6.3 pounds). Macrocephaly, a related condition, refers to an abnormally large head
