Fast and Slow Gene Expression Changes in Blood Following Acute Social Stress

This study identifies fast and slow gene expression changes in human blood after acute social stress, revealing distinct immune cell-related transcriptional responses and potential molecular mechanisms linking stress to psychiatric disorders.

Genetic Influences on Neural Responses in Placebo Analgesia Circuitry

This study quantifies the heritability of neural activation in placebo analgesia circuitry using twin data, finding additive genetics account for 21-49% of variance in pain-evoked brain activity.

Whole Brain Correlates of Individual Differences in Skin Conductance Responses during Human Fear Conditioning

This study identifies brain regions correlated with individual differences in skin conductance responses during fear conditioning using whole brain analysis.

Gray Matter Differentiation Between Two Subordinate Personality Traits of Extraversion: Enthusiasm and Assertiveness

The paper examines the neural basis of two subordinate extraversion traits, finding a significant interaction in the left angular gyrus between enthusiasm and assertiveness.

Dopamine facilitates fear memory formation in the human amygdala

This study shows dopamine release in the human amygdala and striatum during fear learning, linked to fear response strength and memory trace activity.

GABA quantification in human anterior cingulate cortex

This study proposes a method combining PRESS and MEGA-PRESS acquisitions for absolute GABA quantification and compares different internal reference metabolites for GABA estimation.
