People who are most sensitive to the pleasurable and rewarding effects of alcohol are at greater risk of developing alcohol use disorders.
Some neurons have the ability to detect and compensate for neighboring neurons, while others do not. The findings shed new light on synaptic plasticity.
Findings suggest prediction may be a general feature of animal nervous systems in supporting quick behavioral changes.
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.
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.
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.
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.
Researchers say they have found no evidence LSD microdosing improves mood or cognitive function.
