Fear processing in the brain - Wikipedia
WEBMany experiments have been done to find out how the brain interprets stimuli and how animals develop fear responses. The emotion, fear, has been hard-wired into almost every individual, due to its vital role in the survival of the individual.
The Biology of Fear - PMC - National Center for Biotechnology …
WEBJan 1, 2013 — Fear can be caused by a wide range of stimuli, from basic unconditioned stimuli to complex symbolic knowledge; and it can in turn trigger core biological responses as well as be modulated volitionally, at least in humans.
Understanding clinical fear and anxiety through the lens of human fear …
WEBFeb 16, 2023 — Many individuals with clinical anxiety fear benign cues and situations (conditioned stimuli) because they are associated with threatening outcomes (unconditioned stimuli). For example, being bullied as a child can lead to an association between social situations (conditioned stimulus) and threat (unconditioned stimulus), and culminate in a ...
