Which of the following is true of the frontal lobe?
They are responsible for consciousness and integration of information.
What is a basal spasm after an aneurysm of the brain?
Basal spasms occur from 3 to 5 days after a brain aneurysm. These spasms can range from mild to severe and can cause bleeding into the brain after the aneurysm. They are also known to cause severe strokes in patients.
What activates the forebrain when there is important information to be processed?
Reticular Activating System.
What gland is associated with the diencephalon?
The diencephalon is located in the brain. It is composed of the thalamus (located at the top of the brain stem) and hypothalamus (located below the thalamus). The hypothalamus is related to causing the pituitary gland to release hormones.
Cerebral dysgenesis hypotonia?
Cerebral Dysgenesis is a nondescript term that describes improper brain development in utero. It is used oftentimes when no specific diagnosis can be made. That being understood, it can usually be detected at birth on a sonogram by 20 weeks. Prognosis and manifestation is varied, but may range from moderate debilitation to severe, with symptoms that may include paralysis, moderate to global mental retardation, high or low muscle tone, clonus, seizures, feeding difficulties, blindness, deafness and impairment that ranges from delayed milestones to global delays.
Cerebral Dysgenesis means "lack of brain development" Agenesis is the worst stage of the condition. This can be characterized by absence of portions of the brain tissue, with the resulting space being filled with cerebral spinal fluid.
Since there is a great range of severity, each individual case must be treated as unique. Many of the most globally affected children with this disorder display an ability to enjoy life and respond to love and attention. The milder cases can walk, talk, eat and perform simple tasks. Care taking can be very involved, but the humanity of each individual must never be overlooked.
The individual potential for development along the lifespan is totally unique to each person, depending upon the degree of functioning brain tissue available and the extent to which brain tissue is utilized. Every child with this impairment benefits from physical, occupational and speech/language therapy. The life span of a child born with cerebral dysgenesis also varies with the degree of involvement and the ability or inability of the body to handle infections. If the lungs are affected due to lack of muscle tone, the ability to handle secretions or the inability to achieve a productive cough, pneumonia is an ongoing threat. The life expectancy of even a globally involved child can be many decades. Some children with cerebral dysgenesis do not survive past one year of age.
Its very important for the parents of any special needs child to get help from the very beginning. There are many avenues for support available depending upon locale and can include: support groups, respite care centers, governmental funding for special needs day care, respite and therapy, among many others.
Life with a disabled child can be very difficult, challenging, stretching, eyeopening and even heart wrenching. It can also be rewarding and the best job you'll ever have!
There needs to be more awareness about this condition and support for families that contend with these congenital anomalies.

Does the third ventricle in brain contain CSF?
The third ventricle, like all ventricles of the brain, contains cerebral spinal fluid.
Why auditory response is quicker than visual?
Because less neural processing is required and the nerve "circuitry" is much simpler for auditory input than for visual input.

Which part of the brain perceives the sense of sight?
The thalamus, occipital lobe, parietal lobe, and temporal lobe all play parts in visual perception.
Most of the processing of visual information occurs in the occipital lobes. If you want to find out if you are left occipital lobe oriented or right occipital lobe orientated, you can try this simple experiment. With both eyes open, look at a small spot on a wall or ceiling across the room from you. Then use one hand and touch the thumb and index fingers together and hold it about arm's length away in front of you and then place the circle you made with your fingers over the spot and alternate closing one eye at a time. You will notice that you can only see the spot with one eye open. It will be the left or the right eye. This shows your dominant vision tendency and whether you prefer to use your left or right eye more.
Is brain death a sudden event or a gradual process?
Brain death can occur suddenly as in the case of trauma to the brain tissue or over time- such as when the brain tissue begins to die from lack of oxygen. An example of this could be heart failure.
What is the function of the neurohypophysis?
Regulate the secretions of the anterior pituitary and, by this means, regulate the secretions of other endocrine glands
What is responsible for sending messages to the hypothalamus and the thalamus?
The hypothalamus is located in the brain. It is responsible for the production of hormones. These hormones regulate certain bodily functions such as thirst, hunger, sleep and body temperature.
What parts of the brain doesn't have blood brain barrier?
Area postrema doesn't have blood brain barrier
What is the medical term meaning the corpus callosum is severed?
Corpus callosotomy is the medical term meaning surgical severing of the corpus callosum.
How much can the human brain hold in gigabites?
About 1 million gigabites.
