Objective(s) The central nucleus of the amygdala (CeA) is a forebrain structure which is important in regulation of ingestive behavior and there is direct and circumstantial evidence to indicate that some circuits involved with feeding behavior include glutamatergic elements. The present study examined whether administration of NMA (N-Methyl-DL-aspartic acid) or MK801 into the CeA altered water...
Patients with Borderline Personality Disorder (BPD) showed reduced volume of amygdala and hippocampus, but similar findings are evident in Posttraumatic Stress Disorder (PTSD). Applying voxel-based morphometry (VBM) in a larger cohort of patients with BPD, we sought to extend earlier findings of volume abnormalities in limbic regions and to evaluate the influence of co-occurring PTSD in BPD pat...
Despite the fact that social anxiety disorder (SAD) is highly prevalent, there have been only a few structural imaging studies. Moreover, most of them reported about a volume reduction in amygdale, which plays a key role in the neural function of SAD. Insula is another region of interest. Its hyperactivity in regard to processing negative emotional information or interoceptive awareness has bee...
In this paper we describe the architecture that allows the modeling of an emotionally intelligent robotic companion dog. We chose to implement this architecture for AIBO, which is a dog-like autonomous robot, developed by Sony. AIBO was developed as an entertainment robot and its ‘mind’ is programmable. The focus of this paper is on creating a complex personality model that provides a realistic...
BACKGROUND Studies imposing rigorous control over lifetime alcohol intake usually have not found smaller hippocampal volumes in persons with posttraumatic stress disorder (PTSD). Since the majority of negative studies have used adolescent samples, it has been suggested that chronicity is a necessary condition for such findings. We have hypothesized that the volumes of hippocampus, amygdale, pre...
The stria terminalis (ST) connects the amygdale (AM) with the hypothalamus, anterior commissure, preoptic area, and septal region. Many animal studies have reported on the anatomy and function of the ST; in contrast, little is known about its anatomy and function in the human brain. In the current study, we attempted to investigate the anatomical characteristics of the ST in the normal human br...
Neuroimaging studies of major depressive disorder (MDD) have consistently observed functional and structural changes of the hippocampus (HP) and amygdale (AY). Thus, these brain regions appear to be critical elements of the pathophysiology of MDD. The HP and AY directly interact and show broad and overlapping intrinsic functional connectivity (iFC) to other brain regions. Therefore, we hypothes...
The aim of this study was to characterize the patterns of brain atrophy in Alzheimer’s disease (AD) patients compared to FTD patients and healthy controls. This study assesses the brain gray matter (GM) and ROI abnormalities jointly to reveal differences in abnormal MRI patterns between the diseases. Hippocampal, amygdala and cingulate gyrus volume was measured by Magnetic Resonance Imaging in ...
BACKGROUND AND PURPOSE Multiple sclerosis (MS) patients are often emotionally disturbed. We investigated anger in these patients in relation to demographic, clinical, and mood characteristics. PATIENTS AND METHODS About 195 cognitively unimpaired MS patients (150 relapsing-remitting and 45 progressive) were evaluated with the State Trait Anger Expression Inventory, the Chicago Multiscale Depr...
OBJECTIVES The relationship between tramadol, as an antinociceptive drug, and locus coeruleus (LC), the main noradrenergic nucleus of the brain that affects regulation and modulation of pain through descending noradrenergic pathways was investigated. MATERIALS AND METHODS Male Sprague-Dawley rats were divided into four groups of 10 rats. The rats were fixed in stereotaxic instrument and then ...
