The neural interface between sensory perception and memory is a central issue in neuroscience, particularly initial memory organization following perceptual analyses. We used functional magnetic resonance imaging to identify anatomic regions extracting initial auditory semantic memory information related to environmental sounds. Two distinct anatomic foci(More)
Proton magnetic resonance spectroscopy was used to compare medial temporal lobe (MTL) concentrations of N-acetylaspartate and choline between former prisoners of war (POWs) with and without posttraumatic stress disorder (PTSD). MTL N-acetylaspartate and reexperiencing symptoms correlated strongly in the POW subjects with PTSD, suggesting a relationship(More)
Threatening stimuli have been found to modulate visual processes related to perception and attention. The present functional magnetic resonance imaging (fMRI) study investigated whether threat modulates visual object recognition of man-made and naturally occurring categories of stimuli. Compared with nonthreatening pictures, threatening pictures of real(More)
In this study, single voxel proton magnetic resonance spectroscopic imaging ((1)H-MRS) and volumetric analysis of hippocampal magnetic resonance imaging (MRI) images were used to determine if any differences in hippocampal biochemistry or volume were present between former prisoners of war (POWs) with and without posttraumatic stress disorder (PTSD) and(More)
Previous studies have reported associations between apolipoprotein E (APOE) genotype, cognitive function, and psychopathology in psychiatric populations. The authors investigated the associations between APOE allele status, memory function, and posttraumatic stress disorder (PTSD) symptom severity in PTSD subjects. Presence of the APOE 2 allele was(More)

Acute mountain sickness (AMS) is a common problem among visitors at high altitude, and may progress to life-threatening pulmonary and cerebral oedema in a minority of cases. International consensus defines AMS as a constellation of subjective, non-specific symptoms. Specifically, headache, sleep disturbance, fatigue and dizziness are given equal diagnostic(More)
To examine the relationship of alcohol craving to symptoms of posttraumatic stress disorder (PTSD), 129 male veterans with chronic PTSD were asked to complete the Obsessive Compulsive Drinking Scale (OCDS), the Mississippi Scale for combat-related PTSD symptoms, and other instruments to assess general psychopathology and lifetime alcohol and substance use.(More)
