Fear, AmygdalaAbstract
Fear is one of the six fundamental emotions that shape humans today, and is key in learning about the brain. Best known for fear and anxiety regulation, the amygdala is the portion of the brain that processes emotions and is the most important region in fear control. Neurotransmitters such as serotonin and norepinephrine aid in the modulation of this emotion throughout the brain, as their distinct receptors and subtypes trigger specific responses that result in the expression of fear. Related to many neurological and psychiatric conditions, fear is the underlying emotion that is involved in certain disorders, and many treatment options and cures are currently being studied. Genetic factors of fear are under research to assist in medical treatment of conditions as well as helping in further understanding the transmission of fear within families. Being present as parts of individuals’ daily emotions as well as research and healthcare, fear and its regulation is an essential part of humans and the brain.
