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 sensiti…
Neuroimaging study reveals structural and functional differences in brain areas associated with emotional regulation in those with personality traits linked to psychopathy or antisocial personality disorder.
Little-known amygdala cells are identified as the key mediator for aggressive behaviors and may drive our angry.
A new study reveals activity in the amygdala remains consistent when a person views neutral stimuli following viewing negative stimuli. The persistent activity increased negative mood and decreased positive feelings.
The activity of different populations of neurons in the amygdala governs whether mice interact with their peers, or indulge in self-centered behaviors.
Following exposure to visual stimuli, the neurons activated by the stimuli remain more active during subsequent sleep. Sleep is vital for these neurons to connect an emotional or fearful memory to a sensory event.
Both the orthonasal and retronasal routes, in addition to our taste buds, shape our taste perception of foods.
Neuroimaging revealed when people saw an anomalous face, the fusiform gyri and amygdala showed significant neural responses. Activity in a region of the left amygdala, which correlated with less pro-social responses to the anomalous face, appeared to r…
Experiencing trauma or extreme stress during childhood can lead to structural changes in the hippocampus and amygdala that can be seen decades later.
Infant children whose mothers experienced neglect when they were young showed altered brain circuitry in areas associated with anxiety and fear response.
Study concludes one reason we may make unwise decisions is our preference for a positive outcome.
Pnoc neurons in the BNST trigger pupillary response and increase heart rate in response to anxiety and fear.
Study identifies inflammatory mechanisms and cellular activity in the amygdala that drives alcohol addiction in mice. Chronic alcohol exposure compromises immune cells in the brain, driving anxiety and alcohol consumption that may lead to the developme…
Study reveals a key role for the ventromedial hypothalamus in fight or flight behaviors. Findings suggest the ventromedial hypothalamus alters in response to social experiences.
Fear and anxiety share overlapping neural circuits. The findings contradict the popular belief that anxiety and fear are distinct emotions with different triggers and segregated brain circuits.
Brain regions associated with emotional processing are not functionally connected in a mature way to areas associated with auditory and visual processing in newborns.
How the brain represents and codes a pleasant outcome can have an impact on decision making.
Protein synthesis in different amygdala neuron populations is essential for storing information about threat and safety.
Study provides contrary evidence to existing theory, finding anxiety and fear reflect overlapping neural circuits.
