Researchers have identified a neural circuit that regulates threat response in mice.
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 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.
Peripheral and brain markers for fear differ in a hormone dependent manner between males and females.
Study identifies six psycho-acoustically distinct types of screams, relaying emotions such as pain, anger, fear, joy, sadness, and pleasure. Non-alarming screams, such as expressions of joy and pleasure, are perceived and processed by the brain more effectively than screams of alarm.
When people hear screams of excited happiness, they tend to confuse the emotion with fear. Researchers say the bias toward categorizing excited and joyfully screams as fear has evolutionary roots.
Constant exposure to images of syringes and people getting the COVID-19 vaccine on TV and social media may discourage those with phobias of needles from getting their shots, researchers report.
