Anterior insular cortex and emotional awareness.
This paper reviews the foundation for a role of the human anterior insular cortex (AIC) in emotional awareness, defined as the conscious experience of emotions. We first introduce the neuroanatomical features of AIC and existing findings on emotional awareness. Using empathy, the awareness and understanding of other people's emotional states, as a test case, we then present evidence to demonstr...
متن کاملAnterior cingulate cortex regulation of sympathetic activity.
the anterior cingulate cortex (ACC) is active in such a wide variety of cognitive and emotional tasks has become an important issue in recent research. In this issue of Brain, Critchley et al. (2003) report changes in heart rate in both cognitive and motor tasks related to the strength of activation in the ACC. They interpret their ®ndings as supporting a view that the anterior cingulate is inv...
متن کاملEvidence of Conjoint Activation of the Anterior Insular and Cingulate Cortices during Effortful Tasks
The ability to perform effortful tasks is a topic that has received considerable interest in the research of higher functions of the human brain. Neuroimaging studies show that the anterior insular and the anterior cingulate cortices are involved in a multitude of cognitive tasks that require mental effort. In this study, we investigated brain responses to effort using cognitive tasks with task...
متن کاملAbnormal spontaneous neural activity in the anterior insular and anterior cingulate cortices in anxious depression.
OBJECTIVE Anxious depression is a distinct clinical subtype of major depressive disorder (MDD) characterized by palpitations, somatic complaints, altered interoceptive awareness, high risk of suicide, and poor response to pharmacotherapy. However, the neural mechanisms of anxious depression are still not well understood. In this study we investigated changes in neural oscillation during the res...
متن کاملError-related anterior cingulate cortex activity and the prediction of conscious error awareness
Research examining the neural mechanisms associated with error awareness has consistently identified dorsal anterior cingulate cortex (ACC) activity as necessary but not predictive of conscious error detection. Two recent studies (Steinhauser and Yeung, 2010; Wessel et al., 2011) have found a contrary pattern of greater dorsal ACC (dACC) activity [in the form of the error-related negativity (ER...
