What is brain display?

Brain imaging is one of the most prominent medical and scientific developments in history. Its consequences are widespread and its use, countless. The ability to see the structure and function of the brain has forever changed the face of medicine.

Neuroimaging has passed a long journey since his discovery by Walter Dandy in 1918. The first images of the brain were taken by the procedure known as contractulography. The doctors drilled holes into the patient's skull and injected air into the lateral brain chambers to get more accurate X -ray images. This procedure, albeit accurate, was extremely risky and invasive. During the 20th and 21st centuries, various, less invasive and more accurate brain display methods were developed.

Electroencephalography, the process of measuring electrical movement in brain activity was also developed soon. In this method, doctors associate electrodes with the scalp of the patient's head to read the electrical activity in the darkness. Although electroencephalography (EEG) has been and is still an effective way of measuring brain activity, countingČE revolutionized the way the world has experienced brain depicting. In the 1970s of the 20th century, the introduction of computer axial tomography (scanning CAT or CT) allowed doctors to use computer X -ray technology to obtain more accurate, three -dimensional brain images. Doctors could see detailed brain cross -sections for the first time.

Positron emission tomography (PET) and one -off emissions of Photon Computer tomography (SPECT) depend on the injection of radioactive tracing machines into the bloodstream. These stoppers work into the brain and the scanner observes where the tracks are collected in the brain. Doctors can use these images to determine whether there are any defects in different parts of the brain.

Magnetic resonance imaging (MRI) uses breaking fields and radio waves instead of radioactive materials to create brain images. Protons in the brain react to these stimuli and create signals that can be used to createClaims the map of the brain. MRI can not only afford an excellent depiction of the brain structure, but can also reveal the way the brain works. Functional MRI (FMRI), along with PET and SPECT scanning, have numerous consequences for the diagnosis and treatment of innumerable diseases and disorders.

Since its onset, the brain imaging has created a diagnosis of numerous neurological disorders, including depression, schizophrenia and bipolar disorders, more tangible. Brain imaging can also determine the symptoms of stroke and dementia before their occurrence. The brain imaging not only supports the diagnosis of neurological disorders, but because it allows the brain reaction to foreign stimuli, is useful in the development of drugs to correct these disorders.
