Abstract:
Emotions do not only serve to assign a particular value to objects or events forming the content of consciousness, but can directly regulate perception, attention, or memory, thus shaping the content of consciousness and action. The talk will describe brain mechanisms by which positive or negative emotional episodes can influence mental states and cognitive functions in a sustained manner, over prolonged period of time following the emotion eliciting events. Using functional neuroimaging in healthy people and psychiatric patients, our work demonstrates dynamic and lasting changes in both activity and connectivity of brain networks following transient emotion episodes.
These effects are strongly modulated by individual affective traits or personality factors. Our findings have implications for better understanding and assessing changes in brain function associated with mood and anxiety disorders.
