New findings reinforce the idea that dementia with Lewy bodies can be pathologically classified as two different and distinct disease types.
The function of the opioid system is connected to eating triggered by external stimuli. The findings could lead to the development of new therapies that target the opioid system to reduce obesity.
Heightened states of arousal altered neural circuits in a brain area associated with decision making, resulting in some neurons changing from decision making to internal state monitors.
Regardless of symptom severity, otherwise healthy young people diagnosed with COVID-19 develop abnormalities with the system that governs the fight-or-flight response in the sympathetic nervous system.
Study reveals how the amygdala plays a role in prepulse inhibition by activating inhibitory neurons in the brain stem of mice. The findings could have positive implications in the development of treatments for schizophrenia, OCD, and other disorders ma…
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.
Saturated fatty acid levels rise in the brain during the formation of new memories, researchers say. The highest levels of saturated fatty acids were found in the amygdala, an area of the brain associated with fear and emotional memories.
The “fight or flight” response in those who sleepwalk is significantly lower than in those who sleep soundly at night.
Depressed middle-aged carriers of the APOEe4 Alzheimer’s genetic variant are at risk of developing tau accumulations in brain areas associated with emotion and memory.
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.
