The amygdala (/ əˈmɪɡdələ /; pl.: amygdalae / əˈmɪɡdəli, - laɪ / or amygdalas; also corpus amygdaloideum; Latin from Greek, ἀμυγδαλή, amygdalē, 'almond', 'tonsil' [1]) is a paired nuclear complex present in the cerebral hemispheres of vertebrates. It is considered part of the limbic system. [2]
The limbic system, also known as the paleomammalian cortex, is a set of brain structures located on both sides of the thalamus, immediately beneath the medial temporal lobe of the cerebrum primarily in the forebrain. [1] Its various components support a variety of functions including emotion, behavior, long-term memory, and olfaction.
The basolateral amygdala and nucleus accumbens shell together mediate specific Pavlovian-instrumental transfer, a phenomenon in which a classically conditioned stimulus modifies operant behavior. [6] [7] One of the main functions of the basolateral complex is to stimulate the fear response. The fear system is intended to avoid pain or injury.
The central nucleus of the amygdala (CeA or aCeN) is a nucleus within the amygdala. [1][2] It "serves as the major output nucleus of the amygdala and participates in receiving and processing pain information." [3][4][5][6] CeA "connects with brainstem areas that control the expression of innate behaviors and associated physiological responses."
Joseph E. LeDoux (born December 7, 1949) is an American neuroscientist whose research is primarily focused on survival circuits, including their impacts on emotions such as fear and anxiety. [1] LeDoux is the Henry and Lucy Moses Professor of Science at New York University, and director of the Emotional Brain Institute, a collaboration between ...
Google Chrome. Google Chrome is a web browser developed by Google. It was first released in 2008 for Microsoft Windows, built with free software components from Apple WebKit and Mozilla Firefox. [15] Versions were later released for Linux, macOS, iOS, iPadOS, and also for Android, where it is the default browser. [16]
Jennifer Lopez just took part in the American Music Awards' 50th anniversary special, where stars like Raye and Mariah Carey lit up the stage on Sunday, October 6. And, yes, this marks her first ...
The Intercalated cells of the amygdala (ITC or ICCs) are GABAergic neurons situated between the basolateral and central nuclei of the amygdala that play a significant role in inhibitory control over the amygdala. [1] They regulate amygdala-dependent emotional processing like fear memory and social behavior.
