What is the most important part of brain?
The lowest part of the brainstem, the medulla is the most vital part of the entire brain and contains important control centers for the heart and lungs.

What is the most common cause of cerebellar disease?
Cerebellar disorders have numerous causes, including congenital malformations, hereditary ataxias, and acquired conditions. Symptoms vary with the cause but typically include ataxia (impaired muscle coordination)….Signs of Cerebellar Disorders.DeficitManifestationHypotoniaDecreased muscle tone8 more rows
What happens if you lose the right side of your brain?
With right hemisphere brain damage (known as RHBD or RHD), a person may have trouble with things like attention, perception, and memory, as well as loss of mobility and control on the left side of the body, since each hemisphere controls functions on the opposite side of the body.
Does the brain feel pain?
The brain itself does not feel pain because there are no nociceptors located in brain tissue itself. This feature explains why neurosurgeons can operate on brain tissue without causing a patient discomfort, and, in some cases, can even perform surgery while the patient is awake.
What are the symptoms of cerebellar damage?
Damage to the cerebellum can lead to: 1) loss of coordination of motor movement (asynergia), 2) the inability to judge distance and when to stop (dysmetria), 3) the inability to perform rapid alternating movements (adiadochokinesia), 4) movement tremors (intention tremor), 5) staggering, wide based walking (ataxic gait …
What happens if your brain stem is damaged?
A brain stem injury can cause dizziness or lack of motor function, with more severe cases resulting in paralysis, coma, or death. Treatment can be extremely expensive, and many victims are unable to work while coping with a brain stem injury.
Can cerebellum repair itself?
Upon injury of the developing mouse cerebellum, endogenous repair mechanisms can heal the brain and prevent behavioral motor deficits.At the right time, with the right cues, the brain can repair itself.
Can a brain dead person come back to life?
Brain death is often confused with other conditions that seem similar, such as coma and vegetative state. Brain death: Irreversible cessation of all functions of the entire brain, including the brain stem. A person who is brain dead is dead, with no chance of revival.
How long does it take for a chicken to die after its head is cut off?
Mike The Headless Chicken lived for 18 months without a noggin after a farmer, in a failed attempt at slaughter, axed off his head and missed the jugular vein. “Miracle Mike” was eye-droppered a milk and water mixture until he met his unexpected death over a year later when he choked on a kernel of corn.
Can you live without a brain stem?
Of course the brain stem which sits at the bottom of the brain and connects to the spine was normal. Since it controls vital functions such as breathing, swallowing, digestion, eye movement and heartbeat, there can be no life without it.
How long can you live without a brain?
This condition is called as Hydranencephaly where the usual cerebral hemispheres are missing and the cranial cavity is filled with just cerebrospinal fluid. But even without a brain, Trevor Waltrip lived for 12 years. Thus he set an example of the limits of human survival without a brain.
Can a person live without cerebellum?
The near-total absence of the cerebellum is a rare congenital condition with a wide phenotypic heterogeneity ranging from a severe to mild impairment of motor, cognitive, and behavioral functions. … This case also shows that it is possible to learn to live without the cerebellum over time.
Can the brain heal?
Your brain does eventually heal itself. This neuroplasticity or “brain plasticity” is the more recent discovery that gray matter can actually shrink or thicken; neural connections can be forged and refined or weakened and severed. Changes in the physical brain manifest as changes in our abilities.
What is the largest human brain?
