Effects of stress hormones on the structure and function of the human brain

Oliver T Wolf
2006 Expert Review of Endocrinology & Metabolism  
In response to stress, the hypothalamus-pituitary-adrenal axis is activated and glucocorticoids are secreted. These hormones exert multiple effects in the periphery as well as the brain.  ...  In parallel, structural alterations are observed in the hippocampus and the prefrontal cortex. However, it seems that plasticity/reversibility is more common than previously thought.  ...  Acknowledgements References Affiliation For reprint orders, please contact Wolf Acknowledgements The work of the author is supported by grants from the German Research Foundation  ...

Stress Prompts Habit Behavior in Humans

L. Schwabe, O. T. Wolf
2009 Journal of Neuroscience  
These results demonstrate for the first time that stress promotes habits at the expense of goal-directed performance in humans.  ...  Based on previous findings showing that stress modulates the interaction of "cognitive" and "habit" memory systems, we asked in the presented study whether stress may coordinate goal-directed and habit  ...  Converging lines of evidence show that stress and the glucocorticoid stress hormones (mainly cortisol in humans) released from the adrenal cortex can operate as a switch between "cognitive" and "habit"  ...
