what is the risk factors of brain in the disease of amygdala?
The amygdalae (Latin, also corpus amygdaloideum, singular amygdala, from Greek αμυγδαλή, amygdalē, ‘almond’, ‘tonsil’, listed in the Gray’s Anatomy as the nucleus amygdalæ)are almond-shaped groups of nuclei located deep within the medial temporal lobes of the brain in complex vertebrates, including humans.Shown in research to perform a primary role in the processing and memory of emotional reactions, the amygdalae are considered part of the limbic system Anatomical subdivisions The regions described as amygdalae encompass several nuclei with distinct functional traits. Among these nuclei are the basolateral complex, the centromedial nucleus and the cortical nucleus. The basolateral complex can be further subdivided into the lateral, the basal and the accessory basal nuclei. Anatomically, the amygdala and more particularly, its centromedial nucleus,may be considered as a part of the basal ganglia. see more on http://en.wikip
Something strange is going on in the amygdala an almond-shaped structure deep in the human brain among people with autism. Researchers at the University of Washington have discovered an increased pattern of brain activity in the amygdalas of adults with autism that may be linked to the social deficits that typically are associated with the disorder. Previous research at the UW and elsewhere has shown that abnormal growth patterns in the amygdala are commonly found among young children diagnosed with autism. The amygdala is popularly associated with the “fight-or-flight response” in dangerous situations. But it has other functions, including identifying faces and situations and evaluating social information such as emotions. The new research shows that brain activation in adults with autism remains elevated long after similar brain regions of typically developed adults have stopped being activated when exposed to a series of pictures of human faces. A decrease in activation over time to
