Happy New Year from Southern St. Joseph County! Pictured here is downtown North Liberty during the holidays in the 1950s. As a resolution, of sorts, I'm going to attempt to update this page more often in 2017. This image, provide by Allen Balsley, is featured in the 2015 book on Southern St. Joseph County, published by Arcadia and the History Press.
Amygdala - Function. 1  The amygdala sends projections to the hypothalamus, the dorsomedial thalamus, the thalamic reticular nucleus, the nuclei of the trigeminal nerve and the facial nerve, the ventral tegmental area, the locus coeruleus, and the laterodorsal tegmental nucleus. [5]
The amygdala is a region of the brain known to be important for responses to threatening situations and learning about threats. Alterations in the amygdala have been reported in psychiatric disorders such as depression, anxiety disorders like PTSD, schizophrenia and autism spectrum disorder.espite the increased levels of stress hormones, monkeys with early amygdala damage exhibit a blunted emotional reactivity to threats, including decreased fear and aggression, and reduced anxiety in response to stress.
