The purpose of this study is to determine whether long-term chronic alcoholism is associated with changes in emotional functioning and brain structure and function.
This research investigates brain structure and function in alcoholics compared to healthy nonalcoholic individuals. Alcoholics have shown impairments in cognitive processing of emotional signals. Some alcoholics are impaired in social skills, and many are unable to implement the strategies for interpersonal interactions that they recommend for themselves. For example, alcoholics have difficulty interpreting non-verbal emotional cues and recognizing facial expressions of emotion. When listening to sentences, alcoholics also have some difficulty judging emotional intonations and emotional content. In our research, we are trying to understand where in the brain these emotional behaviors take place, and whether or not the brain functions differently for alcoholic and nonalcoholic individuals. We present emotional words and pictures on a computer screen, and using MRI scans, we observe how the brain works when people purposefully respond to the words and pictures. Additionally, we are comparing brain structure and activation patterns in men and women, because there may be gender differences in responses to emotional stimuli.

The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.
A technique applicable to the wide variety of substances which exhibit paramagnetism because of the magnetic moments of unpaired electrons. The spectra are useful for detection and identification, for determination of electron structure, for study of interactions between molecules, and for measurement of nuclear spins and moments. (From McGraw-Hill Encyclopedia of Science and Technology, 7th edition) Electron nuclear double resonance (ENDOR) spectroscopy is a variant of the technique which can give enhanced resolution. Electron spin resonance analysis can now be used in vivo, including imaging applications such as MAGNETIC RESONANCE IMAGING.
Spectroscopic method of measuring the magnetic moment of elementary particles such as atomic nuclei, protons or electrons. It is employed in clinical applications such as NMR Tomography (MAGNETIC RESONANCE IMAGING).
A type of MAGNETIC RESONANCE IMAGING that uses only one nuclear spin excitation per image and therefore can obtain images in a fraction of a second rather than the minutes required in traditional MRI techniques. It is used in a variety of medical and scientific applications.
The creation of a visual display of the inside of the entire body of a human or animal for the purposes of diagnostic evaluation. This is most commonly achieved by using MAGNETIC RESONANCE IMAGING; or POSITRON EMISSION TOMOGRAPHY.
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
