Fear is an intensely unpleasant emotion in response to perceiving or recognizing a danger or threat. Fear causes psychological changes that may produce behavioral reactions such as mounting an aggressive response or fleeing the threat. Fear in human beings may occur in response to a certain stimulus occurring in the present,or in anticipation or expectation of a future threat perceived as a risk to oneself. The fear response arises from the perception of danger leading to confrontation with or escape from/avoiding the threat,which in extreme cases of fear can be a freeze response. The fear response is also implicated in a number of mental disorders,particularly anxiety disorders.
The amygdala is a paired nuclear complex present in the cerebral hemispheres of vertebrates. It is considered part of the limbic system. In primates,it is located medially within the temporal lobes. It consists of many nuclei,each made up of further subnuclei. The subdivision most commonly made is into the basolateral,central,cortical,and medial nuclei together with the intercalated cell clusters. The amygdala has a primary role in the processing of memory,decision-making,and emotional responses. The amygdala was first identified and named by Karl Friedrich Burdach in 1822.
Psychology is an academic and applied discipline involving the scientific study of human mental functions and behavior. Occasionally,in addition or opposition to employing the scientific method,it also relies on symbolic interpretation and critical analysis,although these traditions have tended to be less pronounced than in other social sciences,such as sociology. Psychologists study phenomena such as perception,cognition,emotion,personality,behavior,and interpersonal relationships. Some,especially depth psychologists,also study the unconscious mind.
Physiological psychology is a subdivision of behavioral neuroscience that studies the neural mechanisms of perception and behavior through direct manipulation of the brains of nonhuman animal subjects in controlled experiments. This field of psychology takes an empirical and practical approach when studying the brain and human behavior. Most scientists in this field believe that the mind is a phenomenon that stems from the nervous system. By studying and gaining knowledge about the mechanisms of the nervous system,physiological psychologists can uncover many truths about human behavior. Unlike other subdivisions within biological psychology,the main focus of psychological research is the development of theories that describe brain-behavior relationships.
Martha Julia Farah is a cognitive neuroscience researcher at the University of Pennsylvania. She has worked on an unusually wide range of topics;the citation for her lifetime achievement award from the Association for Psychological Science states that “Her studies on the topics of mental imagery,face recognition,semantic memory,reading,attention,and executive functioning have become classics in the field.”
Affective neuroscience is the study of how the brain processes emotions. This field combines neuroscience with the psychological study of personality,emotion,and mood. The basis of emotions and what emotions are remains an issue of debate within the field of affective neuroscience.

Emotion can have a powerful effect on humans and animals. Numerous studies have shown that the most vivid autobiographical memories tend to be of emotional events,which are likely to be recalled more often and with more clarity and detail than neutral events.
Consumer neuroscience is the combination of consumer research with modern neuroscience. The goal of the field is to find neural explanations for consumer behaviors in individuals both with or without disease.
The management of traumatic memories is important when treating mental health disorders such as post traumatic stress disorder. Traumatic memories can cause life problems even to individuals who do not meet the diagnostic criteria for a mental health disorder. They result from traumatic experiences,including natural disasters such as earthquakes and tsunamis;violent events such as kidnapping,terrorist attacks,war,domestic abuse and rape. Traumatic memories are naturally stressful in nature and emotionally overwhelm people's existing coping mechanisms.
Emotion perception refers to the capacities and abilities of recognizing and identifying emotions in others,in addition to biological and physiological processes involved. Emotions are typically viewed as having three components:subjective experience,physical changes,and cognitive appraisal;emotion perception is the ability to make accurate decisions about another's subjective experience by interpreting their physical changes through sensory systems responsible for converting these observed changes into mental representations. The ability to perceive emotion is believed to be both innate and subject to environmental influence and is also a critical component in social interactions. How emotion is experienced and interpreted depends on how it is perceived. Likewise,how emotion is perceived is dependent on past experiences and interpretations. Emotion can be accurately perceived in humans. Emotions can be perceived visually,audibly,through smell and also through bodily sensations and this process is believed to be different from the perception of non-emotional material.
Daniela Schiller is a neuroscientist who leads the Affective Neuroscience Lab at the Mount Sinai School of Medicine. She is best known for her work on memory reconsolidation,and on modification of emotional learning and memory.
Jee Hyun Kim is an Australian behavioral neuroscientist whose work focuses on emotional learning and memory during childhood and adolescence. She is a professor,ARC future fellow,and head of the Molecular Psychiatry Laboratory at the Deakin University School of Medicine,Australia
Stephen Andrew Maren is an American behavioral neuroscientist investigating the brain mechanisms of emotional memory,particularly the role context plays in the behavioral expression of fear. He has discovered brain circuits regulating context-dependent memory,including mapping functional connections between the hippocampus,prefrontal cortex,and amygdala that are involved in the expression and extinction of learned fear responses.
Elizabeth Kensinger is Professor of Psychology and Neuroscience at Boston College. She is known for her research on emotion and memory over the human lifespan. She is co-author of the book Why We Forget and How To Remember Better:The Science Behind Memory,published in 2023 by Oxford University Press,which provides an overview of the psychology and neuroscience of memory. She also is the author of the book Emotional Memory Across the Adult Lifespan, which describes the selectivity of memory,i.e.,how events infused with personal significance and emotion are much more memorable than nonemotional events. This book provides an overview of research on the cognitive and neural mechanisms underlying the formation and retrieval of emotional memories. Kensinger is co-author of a third book How Does Emotion Affect Attention and Memory? Attentional Capture,Tunnel Memory,and the Implications for Posttraumatic Stress Disorder with Katherine Mickley Steinmetz,which highlights the roles of emotion in determining what people pay attention to and later remember.
