AmygdalaaggressionMRIvolumetryhealthy volunteersObjective. Several lines of evidence suggest an association between the amygdala and the modulation of aggressive behaviour. Previous morphometric brain imaging studies have focused on the role of the amygdala in the context of pathologic neuropsychiatric ...

Several studies support that amygdala react to both negative and positive stimuli.45, 46, 47, 48, 49 Hyperactivity of the amygdala has also been reported in the luteal, as compared with the follicular, phase of the menstrual cycle in healthy women when estradiol levels are decreasing.6, 11,...
Further, the described functional imaging studies suggested that the key role of the amygdala was in the generation of social bias, prejudice, and stereotypes. They also suggested the importance of (a) the areas of the network con- sisting of the dorsolateral, ventrolateral, frontal, and ...

Adaptive responses to stressful stimuli involving behavioral, emotional and metabolic changes are orchestrated by the nervous and endocrine systems. Adipose tissue has been recognized as a highly active metabolic and endocrine organ, secreting adipokines
Latrophilins (LPHNs) are adhesion G protein-coupled receptors with three isoforms but only LPHN3 is brain specific (caudate, prefrontal cortex, dentate, amygdala, and cerebellum). Variants of LPHN3 are associated with ADHD. Null mutations of Lphn3 in rat, mouse, zebrafish, and Drosophila res...
Brain imaging studies have found increased amygdala activity to negative stimuli after sleep deprivation, and reduced functional connectivity with regulatory regions (Yoo et al., 2007, Motomura et al., 2013). As well, total sleep deprivation was associated with increases in activation in mesolimbic ...
Selective deletion of the leptin receptor in dopamine neurons produces anxiogenic-like behavior and increases dopaminergic activity in amygdala. Mol Psychiatry 2011; 16: 1024–1038. 11 Guo M, Lu Y, Garza JC, Li Y, Chua SC, Zhang W et al. Forebrain glutamatergic neurons mediate leptin action ...
Amygdala plays a crucial role in the generation of emotions: a large body of evidence suggests that amygdala activation to emotional faces increases between age 3 and 9years [ 2 ], indicating that amygdala reactivity underlies an increasing sensitivity to emotionally relevant information. In turn, ...
