Microglia, a key immune cell in the brain, appears to mediate the relationship between the gut microbiome and amyloid-beta deposits in male mouse models of Alzheimer's disease.
Frequency follow response (FFR) is a strong predictor of a person's ability to recognize and name musical notes, and may be an accurate metric for understanding a person's ability to recognize sounds. FFR may not be a fixed trait and can be improved over time.
Self-reported engagement in the narrative of a TV show synchronizes across people at the same points in the storyline. The synchronization was driven by the emotional content of the narrative. Neuroimaging reflected the similarities in brain activity synchronization at the same points of the story across the subject participants.
Nitrous oxide, a common anesthesia most often associated with dental procedures, may have a new purpose. Researchers found a single inhalation of 25% nitrous oxide gas was effective at alleviating symptoms of depression in those with a treatment-resistant form of the mental health disorder.
Findings suggest prediction may be a general feature of animal nervous systems in supporting quick behavioral changes.
Some neurons have the ability to detect and compensate for neighboring neurons, while others do not. The findings shed new light on synaptic plasticity.
People who are most sensitive to the pleasurable and rewarding effects of alcohol are at greater risk of developing alcohol use disorders.
While people with aphantasia lack visual imagery ability, they have intact spatial memory. Findings suggest mental imagery recall and spatial memory may be stored differently in the brain.
People with strong moral and political convictions who saw images of protestors congruent to their own views showed activation in the brain's reward system. The study suggests violent acts in political protests can arise as a desire to act morally, rather than from bad intentions.
By fusing a cytokine to a blood protein, researchers have developed a new therapy to help treat multiple sclerosis.
