Sex differences in prefrontal cortical brain activity during fMRI of auditory verbal working memory. Exogenous testosterone also increases amygdala reactivity to threatening faces, but reduces functional coupling between the amygdala and OFC in middle-aged women, suggesting that the testosterone may regulate interactions between amygdala and OFC [ ].

Ledoux JE: Emotion circuits in the brain. In order to fully understand the role of estrogen in fear extinction, it is necessary to identify the molecular cascades by which estrogen may enhance extinction memory and investigate sex differences in estrogen action within the extinction network.

Developmental origins, statistical characteristics, and functional expression of sex differences in the brain. Central depletion of brain-derived neurotrophic factor in mice results in high bone mass and metabolic phenotype. Female veterans with TBI: functional connectivity between right orbitofrontal cortex and other regions.

The data reviewed above indicate that sex hormones in rodents and humans may contribute to differences in fear learning and fear extinction. Female rats generalize contextual fear at a faster rate than males and this effect is due to estradiol [ 41 ]. Epilepsia, 44 Suppl 10 , 2— In support of this, systemic pre- or post-extinction administration of estradiol into female rats undergoing extinction learning in the metestrus phase low estrogen and progesterone significantly reduced freezing during recall Figure 4a, b [ 75 ].

Examining the functional effect of BDNF administration in animals lacking the sex steroid receptors would provide some insights.
