In anxiety, neural activity becomes elevated across many specific brain regions, and normal coordination between the networks becomes decreased.
New evidence suggests the brain can update poorly formed memories with incorrect information, leading to the creation of false memories.
Stress alters how we process and share risky information. Researchers report people were less likely to amplify fears in conversations when they were feeling stressed.
Study provides insight into the neural mechanisms of how prey animals use the sounds or actions of others to infer danger and respond defensively.
The ability to extinguish fear memories may rely on the flexibility of a person's DNA.
The formation of fear memories involves the strengthening of neural pathways between the hippocampus and the amygdala.
Spending time outdoors and helping to control fears can help children process their negative emotions.
Study sheds light on the process of death and questions if people experience a state of euphoria during their final moments.
Fear and physiological tension can be reduced by the mere presence of another person, even if the person is unknown and does not offer support.
Neuroimaging reveals areas of the brain associated with visual and auditory processing are more active when anxiety slowly increases during horror movies. After a shocking scene, brain areas associated with emotional processing, threat evaluation, and decision making increase in activity.
Fear extinction memories and feelings of reward are both stored in neurons that express the Ppp1r1b gene in the posterior of the basolateral amygdala.
Mice infected with the Toxoplasma gondii parasite showed no selective reduction in fear of feline predators. Findings reveal chronic T. gondii infection reduces anxiety and risk-aversion while increasing curiosity and exploratory behaviors.
