PSYCHONEUROENDOCRINOLOGY

The influence of psychological states on the endocrine system

Stress and Mitochondria

Psychological stress alters mitochondria, organelles within human cells, changing their morphology, metabolism, and signaling.

Stress, Learning, and Memory

Learning in stressful conditions worsens memory formation (for both free recall and recognition).

Maternal Care and the Stress Response

The hypothalamic-pituitary axis that mediates the stress response is dysregulated in individuals lacking maternal care.

Stress and Learning Rate

Stress triggered by a learning experience can rapidly affect information processing (and, thus, the learning rate) through rapid actions of glucocorticoids in hippocampal memory circuits.

Stress and Anxiety

Stress has opposite effects on self-confidence and competitiveness in highly anxious and low anxious individuals, making the former become highly underconfident while the latter overconfident.

Stress Reactivity, Sex, and Sexual Orientation

Birth-assigned men show more heightened physiological stress (cortisol) reactivity than birth-assigned women. Additionally patterns of cortisol reactivity appear to be distinct in individuals of specific sexual orientations.
