May 31, 2021 · Neuronal circuits involving the amygdala, hippocampus, and PFC are responsible for fear response control, while modulation of amygdala activity mainly depends on the vmPFC. From an evolutionary perspective, due to the adaptive role in adverse events, the complete absence of anxiety would likely be detrimental.

Jan 17, 2024 · The limbic system is a network of brain structures involved in emotion, memory, and behavior regulation. The hippocampus and amygdala are key components of the limbic system, responsible for memory formation, spatial navigation, fear learning, and emotional responses.
Dec 14, 2023 · The amygdala is a brain structure that processes emotions, especially fear, and links them to memories. It is near the hippocampus, which is involved in memory formation and storage. Learn more about the amygdala's functions, connections, and disorders.
The hippocampus is a part of your limbic system and is connected to the hypothalamus and amygdala. These structures help regulate various bodily functions, including the “fight-or-flight” response. Imagine you see a dog for the first time. The dog wags its tail and licks your hand when it sees you.
Oct 30, 2023 · Learn about the hippocampus, a paired structure in the temporal lobe of the brain that is part of the limbic system and involved in learning and memory. Find out its internal structure, layers, fields, afferent and efferent pathways, and clinical correlations.

Jul 20, 2023 · The hippocampus is closely associated with the amygdala, hypothalamus, septum, and mammillary bodies such that any stimulation of the nearby parts also marginally stimulates the hippocampus. There are also high outgoing signals from the hippocampus, especially through the fornix into the anterior thalamus, hypothalamus, and greater limbic system.
