The modern technology allows the researcher to know more about the cognitive processes. Neuron-imaging techniques allow the researchers to learn about the brain structure and functions. This will help them to understand the difference and the relationship between cognitive process and behavior. There are different types of brain imaging technologies: PET- Positron Emission Topography, MRI- Magnetic Resonance Imaging, frMri- functional Magnetic Resonance Imaging EEG: Electroencephalogram and CAT- Computerized Axial Tomography. The brain imaging technologies are used in different situations and it has its own advantages and disadvantages. (IB Guides)

in 2001. The aim of the study is use PET scan, to study “the bilingual language compensation following early childhood brain damage” (IB Guides). The patient was known as MA he was 37years old with normal speech and was participating in a normal speech study. He had a lesion in his left frontal lobe and that resulted of encephalitis that occurred at age of 6 weeks but it didn’t have any long term consequences. His parents were deaf and he used sign languages at home from a very young age. In the research, the researchers compared MA to 12 other participants (control) and they were fluent in sign language. The PET scan was used while the participants produced narrative speech or signs. The results shows that MA’s right hemisphere was more active than the control’s during both speech and sign production. This showed that Language was developed in the right hemisphere instead of the left because of his adaptation of his brain damage. PET scan was used to observe the cognitive process of language and observe the areas of the brains that activated MA’s language production. (IB
