Abstract Dysregulation of autonomic cardiovascular homeostasis is an important cardiological and neurological risk factor. Cortical regions including the prefrontal and insular cortices exert tonic control over cardiovascular autonomic functions. Transcranial Magnetic Stimulation (TMS) may be a suitable approach for studying top-down control of visceromotor processes. However, there is inconsistent evidence as to whether TMS can modify cardiovascular autonomic states. One reason for the inconsis...

Abstract Aim Substance use disorders (SUDs) are highly comorbid with post-traumatic stress disorder (PTSD). PTSD-SUD comorbidity is associated with greater functional impairments and relapse risk. Women with SUDs experience markedly higher rates of trauma and PTSD compared to men with SUDs, particularly due to sexual and domestic abuse. Despite the strong association between trauma exposure and SUDs, the neurobiological correlates are understudied, particularly among females with SUDs. However, ...

Transcranial direct current stimulation (tDCS) is a potential treatment strategy for mood and anxiety disorders, but how this application may influence emotional processes, and whether this is related to individual characteristics, is not well understood. It has been proposed that perceived criticism (PC) may represent a vulnerability factor for the development of such mental illnesses. To decipher whether neural mechanisms of action of tDCS potentially differ depending on PC status (low vs. hig...

Nowadays, sports betting has become increasingly available and easy to engage in. Here we examined the neural responses to stimuli that represent sporting events available for betting as compared to sporting events without a gambling opportunity. We used a cue exposure task in which football (soccer) fans (N = 42) viewed cues depicting scheduled football games that would occur shortly after the scanning session. In the "betting" condition, participants were instructed to choose, at the end of ea...

The somatic marker hypothesis is one of the most influential neurocognitive theories of emotion and decision-making. A key aspect of the somatic marker hypothesis is the ‘body-loop’, which is the claim that emotive events that are expressed in the body can influence decision-making via afferent feedback to the brain. The body-loop has often been the subject of debate. However, evidence for the neural and peripheral mechanisms that support interactions between bodily states and cognitive function...

The roots of immoral behavior may be traced to dysfunction within neural regions that integrate emotion and decision making. Individuals who engage in immoral behavior are in some ways similar to individuals with psychopathy. While these behaviors have long been discussed within the realm of social science and psychology, only recently the neurobiological roots of these behaviors began to unfold. We review evidence from brain lesion, neuroimaging, and genetic studies, which indicate that immoral...
