Human brain in the coronal orientation. Amygdalae are shown in dark red. The amygdala (/ ə ˈ m ɪ ɡ d ə l ə /; pl.: amygdalae / ə ˈ m ɪ ɡ d ə l i,-l aɪ / 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.
The amygdala is involved in memory consolidation, which is the process of transferring information that is currently in working memory into ones long-term memory. This process is also known as memory modulation. [7] The amygdala works to encode recent emotional information into memory.
Besides memory, the amygdala also seems to be an important brain region involved in attentional and emotional processes. First, to define attention in cognitive terms, attention is the ability to focus on some stimuli while ignoring others. Thus, the amygdala seems to be an important structure in this ability.
It is the most peptide-rich region of the brain. [8] The amygdalofugal pathway connects the central nucleus of the amygdala to the brainstem. The stria terminalis does so also but in a longer, less direct route. [9] These connections collectively are involved with emotional responses. [13]
Such brain parts as the cerebellum, striatum, cerebral cortex, hippocampus, and amygdala are thought to play an important role in memory. For example, the hippocampus is believed to be involved in spatial and declarative memory, as well as consolidating short-term into long-term memory.
“The best brain exercises involve things you've always liked to do,” Dr. Portnoy says. This can look like card games, joining a jigsaw puzzle club or playing board games together.
These stimuli activated not only the hippocampus but also other brain structures. He theorized that these brain structures worked together as the emotional control center in the brain and consequently founded the Papez circuit. [19] Because of these studies, Papez strongly believed that the circuit was the cortical control of emotion.
The limbic system includes the structures of the brain that control emotions, memories, and arousal. [4] Through the prefrontal cortex, the system plays a role in the expression of moods and emotional feelings. [5] The structures most involved with Limbic Imprint are known as the hippocampus and amygdala.
