Transcript of brain
The human brain has been called the most complex object in the known universe, and in many ways it's the final frontier of science.
A hundred billion neurons, close to a quadrillion connections between them, and we don't even fully understand a single cell.
triplet size in 7 million year, with most of this growth occurring in the past two million years.
Luccy fossil Australopithecus afarensis internal volumes of between 400 and 550 milliliters, and gorillas between 500 and 700 ml. brains started to show subtle changes in structure and shape reorganizing its functions.
saw a modest hop in brain size, including an expansion of a language-connected
1,200 ml or more. As our cultural and linguistic complexity, dietary needs and technological prowess With some evolutionary irony, the past 10,000 years of human existence actually shrank our brains
technique of integration
In normal conditions we are capable of using both hemispheres for the perception and assimilation.
the sressful OR NEGATIVE information remains like "blocked" in the right hemisphere, without this one could be compared with the vision of the left-handed.
By means of the bilateral alternate stimulation there are activated sequentially both cerebral hemispheres of the patient, achieving that the traumatic information is re-processed and joins on having happened from the right hemisphere to the left-handed.
Disorders of anxiety, assaults of panic, phobias, fears,
The evolution in the STUDIES ABOUT brain has ADVANCED A LOT from 1968, when it was achieved to obtain the first not invasive image of diagnosis of the governing organ of the nervous system.
The people who suffer Pick's disease have abnormal substances (called Pick's bodies and Pick's cells) inside the neurons in the damaged areas of the brain...
The persons with Pick's disease tend to behave of way mistaken in diverse social scenes.. Some persons will have more difficulty with the capture of decisions.
34 specialists, who do not understand the strange conservation of the interior on having been exposed to water, oxygen or temperatures where the bacteria can be active. The investigation suggests that the head was cut very rapidly and the man buried immediately in a hole in rich soil in humid clay. " Since there was no trace of oxygen, and there is no movement, it was protected and preserved ".
Seize neurons of the tonsil of the human brain that get excited electrically after the assault of a dog they remain connected for years. His electrical bridges are reinforced. This it would be the skeleton of the recollection.
Fear is a chain reaction in the brain that starts with a stressful stimulus and ends with the release of chemicals that cause a racing heart, fast breathing and energized muscles, among other things, also known as the fight-or-flight response.
Brain stem death
How brain death occurs
Brain death can occur when the blood and/or oxygen supply to the brain is stopped. This can be caused by:
But also it can occur as a result of: a severe head injury
a brain haemorrhage
infections or brain tumor.
migraine tensional. painful
migraine in outbreaks. Incapacitating
15 days every month 1,7 % to 4 % of the adult population of the world.
At least once in the last year 47 % (ADULTS)
Epilepsy is a chronic noncommunicable disorder of the brain that affects people of all ages.
Around 50 million people worldwide have epilepsy.
Nearly. ( 80% developing regions)
brain damage from prenatal or perinatal injuries (a loss of oxygen or trauma during birth, low birth weight);
a severe blow to the head;
a stroke that starves the brain of oxygen;
an infection of the brain
a brain tumor.
encephalic disorder of chronic and progressive deterioration that is accompanied of deep effects in the aptitude to remember, learning and reasoning.
evolves progressively during a period of years.
(between eight and ten years), though sometimes it is two or three years
CAPACITY OF WORK.
Problems of language . Disorientation in the time and the space.
Problems of abstract thought
Changes of humor and of conduct. Changes in the personality. Loss of initiative (passiveness).
Magnetic resonance (MR).
Computed axial tomography (cat) .
System that analyzes several X-ray photographies by means of a computer, which generates images in high resolution, similar to anatomical cuts of the brain .
The cerebral death is the irreversible loss of the cerebral activity, included the trunk of the encephalon. This happens for a serious injury in the head or a hemorrhage that provokes the loss of oxygenation the brain. the patient does not show potential of conscience, that is the difference with vegetative state.
