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.
DHA may be more effective at reducing chronic inflammation than EPA.
Researchers have identified a molecular mechanism that disrupts the flow of enzymes in axons, results in the accumulation of amyloid plaques.
When people were warned about the inaccuracy of retelling events, they were less susceptible to misinformation. Providing warnings increased reinstatement of visual activity associated with witnessing an event and decreased the reinstatement of auditory activity associated with hearing misleading post-event information.
Researchers have uncovered a neural mechanism in female mice that shifts estrogen from playing a protective role in glucose metabolism to a disruptive one.
Tufts researchers have developed neurotransmitter-lipid hybrids that help transport therapeutic drugs and gene editing proteins across the blood-brain barrier in mice.
The SSRI sertraline (Zoloft), if taken while pregnant, can result in birth defects caused by the drug damaging a cell's genetic information. Researchers report one potential way to counter the effect is with specific antioxidants.
