Answer: The objective of this analysis is to review a spectrum of functional brain imaging technologies to identify whether there are any imaging modalities that are more effective than others for various brain pathology conditions. This evidence-based analysis reviews magnetoencephalography (MEG), magnetic resonance spectroscopy (MRS), positron emission tomography (PET), and functional magnetic resonance imaging (fMRI) for the diagnosis or surgical management of the following conditions: Alzheimer’s disease (AD), brain tumors, epilepsy, multiple sclerosis (MS), and Parkinson’s disease (PD).
The reporter interpreted the findings correctly. In Ontario, there will be an estimated 950 new cases and 580 deaths due to brain cancer in 2006. Treatments for brain tumors include surgery and radiation therapy. However, one of the limitations of radiation therapy is that it damages tissue though necrosis and scarring. Computed tomography (CT) and magnetic resonance imaging (MRI) may not distinguish between radiation effects and resistant tissue, creating a potential role for functional brain imaging.

Answer: in-groups and out-groups
Explanation: In-group is a group where two or more individuals who interact with themselves, share the same traits and to which an individual has a feeling of being united, in membership, belonging and close similarities.
Out-group is, therefore, a social group whereby the person doesn't have a feeling of being united, in membership, belonging and close similarities. However, there is always a certainty that individuals will tend to choose and have a natural liking and understanding for their in-group over the out-group.
