Are you a Doer or a Procrastinator?
Scientists at the Ruhr-Universitaet Bochum in Germany examined the brains of 264 healthy volunteers who were also asked to complete a survey assessing their ability for initiating actions and action control. The data analysis revealed that the size of one’s amygdala and the strength of its connectivity with the dorsal Anterior Cingulate Cortex (dACC) correlate with one’s self-reported ability to control their actions. Participants with over-sized and over active amygdala and a weaker connectivity between the amygdala and the dACC exhibited (self-reported) poor action control, while participants with smaller amygdala, densely connected with the dAC, were able to initiate actions better. Similar pattern of activation and connectivity between amygdala and two further corticolimbic structures- the ventro-medial prefreontal cortex (VMPC) and the dorso-lateral prefrontal cortex has been reported to correlate with one’s capacity for voluntarily and deliberate emotion control.
