Article Abstract
Posttraumatic stress disorder (PTSD) and substance use disorders (SUD) are complex psychiatric conditions that commonly co-occur. Research on PTSD-SUD comorbidity has increasingly focused upon better understanding biopsychosocial factors that may contribute to their co-occurring etiology, maintenance, and treatment. Anhedonia, defined as a lack of pleasure from or interest in rewards, stems from deficits in reward functioning and is associated with specific neurocircuitries. Few studies have investigated the role of reward functioning in PTSD-SUD. The overarching aims of this review are to: define the major facets of reward functioning, summarize the research on reward functioning-PTSD and reward functioning-SUD, review the literature on associations between reward functioning and PTSD-SUD comorbidity, and discuss clinical implications and future directions.
Introduction: Carbonated water (CarbW) affects the swallowing function associated with the action of the brainstem. In addition, CarbW ingestion promotes mean blood flow in the middle cerebral artery, which is associated with blood flow to the frontal and temporal lobes. In this milieu, studies regarding the effect of drinking CarbW on brain activity are of significance.
Background: Accruing evidence suggests that personality-based approaches to eating disorder classification may offer several advantages over current diagnostic models, with prior research consistently identifying three personality-based groups characterized by either (1) high levels of impulsivity and dysregulation (termed the "undercontrolled" group), (2) high levels of rigidity and avoidance (termed the "overcontrolled" group), or (3) relatively normative levels of personality functioning (termed the "low psychopathology" group). Cognitive inflexibility (i.e.
Microscopic imaging is a critical tool in scientific research, biomedical studies, and engineering applications, with an urgent need for system miniaturization and rapid, precision autofocus techniques. However, traditional microscopes and autofocus methods face hardware limitations and slow software speeds in achieving this goal. In response, this paper proposes the implementation of an adaptive Liquid Lens Microscope System utilizing Deep Reinforcement Learning-based Autofocus (DRLAF).
The Early Career Awards, given for the first time in 1974, recognize the large number of excellent early career psychologists. Recipients of this award may not have held a doctoral degree for more than nine years. Anna E.
Macroautophagy, a universal cellular process, sends cellular material to lysosomes for breakdown and is often activated by stressors like hypoxia or drug exposure. It is vital for protein balance, neurotransmitter release, synaptic function, and neuron survival. The role of macroautophagy in substance use disorders is dual.
