Researchers have identified a new target in the brain that underpins the freezing response associated with anxiety and fear. The findings could provide a new drug target for anxiety-related disorders.
The presence of friends increases arousal when people are exposed to scary stimuli, researchers report. Additionally, the stronger the response to the initial stimuli, the more fear response increases when exposed to subsequent scary stimuli.
Study reveals how the brain relies on feedback from the body to regulate fear response. When a mouse's body freezes in response to fear, its heart rate slows, and this leads to attenuated insular cortex activity.
Researchers have identified a pre-programmed neural circuit in the basolateral amygdala of mice that processes both positive and negative stimuli.
Researchers investigate why many of us wake in the middle of the night and dwell on our fears.
Researchers have identified a neural circuit that regulates threat response in mice.
A newly developed augmented reality smartphone app may help reduce the fear of spiders for arachnophobes.
A new mathematical model incorporates fear, both of infection and vaccination, to better understand how pandemics occur in multiple waves of infection, as we are witnessing with COVID-19.
The central amygdala isn't only the hub for fear response in the brain, it also contains microcircuits that regulate the suppression of fear response.
Study reveals a significant association between an infant's gut microbiome and their fear response.
The apical intercalated cell cluster (apITC), a specialized portion of inhibitory circuitry in the amygdala, has rich connectivity and plays a unique role in modulating synaptic plasticity.
A new study sheds light on how highly sensitive people process information. After experiencing something emotionally evocative, brain activity displayed a depth of processing while at rest. Depth of processing is a key feature of high emotional sensitivity.
