Epigenetics of anxiety and stress–related disorders is the field studying the relationship between epigenetic modifications of genes and anxiety and stress-related disorders, including mental health disorders such as generalized anxiety disorder (GAD), post-traumatic stress disorder, obsessive-compulsive disorder (OCD), and more.
A repeat length polymorphism in the promoter of this gene has been shown to affect the rate of serotonin uptake and may play a role in sudden infant death syndrome, aggressive behavior in Alzheimer disease patients, post-traumatic stress disorder and depression-susceptibility in people experiencing emotional trauma.

Behavioral epigenetics is the field of study examining the role of epigenetics in shaping animal and human behavior. [1] It seeks to explain how nurture shapes nature, [2] where nature refers to biological heredity [3] and nurture refers to virtually everything that occurs during the life-span (e.g., social-experience, diet and nutrition, and exposure to toxins).

$16.23 at amazon.com. Serotonin promotes a sense of calm, well-being, and happiness. Low serotonin levels can lead to irritability and anxiety, which, along with making you generally cranky, can ...
Human karyogram. Neurogenetics studies the role of genetics in the development and function of the nervous system.It considers neural characteristics as phenotypes (i.e. manifestations, measurable or not, of the genetic make-up of an individual), and is mainly based on the observation that the nervous systems of individuals, even of those belonging to the same species, may not be identical.
Any damage to the brain can cause a mental disorder. The brain is the control system for the nervous system and the rest of the body. Without it, the body cannot function properly. [71] Increased mood swings, insane behavior, and substance abuse disorders are traumatic brain injury (TBI) examples. Findings on the relationship between TBI ...
The brain is an information processing device, and it produces behavior in response to external and internal inputs. [5] [21] The brain's adaptive mechanisms were shaped by natural and sexual selection. [5] [21] Different neural mechanisms are specialized for solving problems in humanity's evolutionary past. [5] [21]
The result of this conditioned stimulus is to provoke the unconditioned response, fear. The once neutral stimulus is given again to see if the rat would show the responses of fear. However, because fear responses involve many behaviors, it is important to see which behaviors are exhibited when the conditioned stimulus is given. [2]
