Scientists identified a gene in the amygdala that can cause anxiety by over-expressing itself. They treated that gene in mice ...

Fear is an adaptive emotion that helps us cope with threatening situations. Deep within the temporal lobe of the brain is the amygdala, the most studied brain area involved in fear. The amygdala uses ...

In contrast to evidence that the amygdala stimulates stress responses in adults, researchers at Yerkes National Primate Research Center, Emory University have found that the amygdala has an inhibitory ...

A new study sheds light--both literally and figuratively--on the intricate brain cell connections responsible for anxiety. Scientists at Stanford University recently used light to activate mouse ...

Has your heart ever started to race at the thought of an upcoming deadline for work? Or has the sight of an unknown object in a dark room made you jump? Well, you can probably thank your amygdala for ...

One of the characteristics of depression is a tendency to perceive sensory stimuli and everyday situations in an excessively negative way. But the mechanisms underpinning this "negativity bias," which ...

If confirmed, such work could pave the way for brain-based therapies that restore emotional stability without heavy ...

Researchers have shown how the amygdala, a brain region typically associated with fear, contributes to prepulse inhibition (PPI) by activating small inhibitory neurons in the mouse brain stem. The ...
