Chronic stress impairs allopregnanolone production in the basolateral amygdala, a brain area associated with mediating emotional response. The reduction of this neurosteroid results in depressive symptoms in animal models.
Study reveals heightened activity in the amygdala in response to seeing surprised or neutral facial expressions could be a biomarker for a risk of developing PTSD following trauma.
Insufficient sleep is associated with an increased risk of obesity, especially in children. Researchers say altering your sleep pattern and getting sufficient sleep each night may be key to reducing weight gain and obesity.
Older adults with cognitive decline who have higher levels of vitamin D in their brains had better cognitive function than their peers with lower levels of vitamin D.
Two common compounds, green tea catechins and resveratrol, a compound found in red wine, reduce the formation of Alzheimer's-associated amyloid plaques in brain tissue.
While the incorporation of healthier legumes and fruits into diets improved over time, dietary quality was offset by the consumption of unhealthy components, such as processed meats and sugar-sweetened drinks.
Varicella zoster virus (VZV), the virus that causes chickenpox and shingles, may activate the herpes simplex virus and trigger the onset of Alzheimer's disease, a new mouse study found.
A new study reveals an association between Alzheimer's disease and Fusobacterium nucleatum, a common bacteria that proliferates in periodontal disease.
Researchers explore how changes in the patterns of activity in the basolateral amygdala contribute to negative emotions such as fear, anxiety, and depression.
The release of potassium ions from neurons charges the electrical activity of astrocytes, allowing for the control of neurotransmission. The astrocyte-neuron crosstalk raises questions as to how the interaction works in brain pathology and the implications for memory and learning.
Like humans, zebra finches can recognize songs by their rhythmic pattern, even when the tempo is changed.
Allopregnanolone, a neuroactive steroid used in the treatment of postpartum depression, alters neural communication in the basolateral amygdala, an area of the brain associated with emotion and mood regulation. The drug may alter the network associated with chronic stress, which may explain its persistent antidepressant effect.
