Chromatin remodeling in rodent offspring and altered gene expression within the limbic brain regions that may contribute to depression, stress, and anxiety-related disorders in future generations. [4] Variations in maternal care, such as maternal licking and grooming, indicates reduced HPA axis reactivity in subsequent generations. [5]
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.
Biology of depression. Scientific studies have found that different brain areas show altered activity in humans with major depressive disorder (MDD), [1] and this has encouraged advocates of various theories that seek to identify a biochemical origin of the disease, as opposed to theories that emphasize psychological or situational causes.
Effects of stress on memory. The effects of stress on memory include interference with a person's capacity to encode memory and the ability to retrieve information. [1][2] Stimuli, like stress, improved memory when it was related to learning the subject. [3] During times of stress, the body reacts by secreting stress hormones into the bloodstream.
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.
Two additional brain structures that have been found to contribute are the amygdala and the anterior cingulate cortex. [90] [91] Each of these structures are involved in various facets of emotion regulation and irregularities in one or more regions and/or interconnections among them are affiliated with failures of emotion regulation. An ...
As a result, stress alters the developmental trajectory of that brain region, producing long-lasting alterations in structure and function. Common types of early life stress that are documented include maltreatment, neglect, and previous institutionalization. Living in poverty has also been shown to similarly influence brain function.

The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain. The ventral medial prefrontal is located in the frontal lobe at the bottom of the cerebral hemispheres and is implicated in the processing of risk and fear, as it is critical in the regulation of amygdala activity in humans.
