Disregarding lab animals' circadian rhythms can hamper reproducibility, validity, and reliability of research, researchers say.
Study reveals the role the ventral tegmental area of the brain plays in craving protein-rich foods.
Researchers have identified three biomarkers in blood samples that confirm the link between exercise and improved cognitive function in older adults.
Chronic gut inflammation can trigger the clumping of alpha-synuclein in the walls of the colon, a new study reports. Researchers found chronic inflammation in the gut during early life can exacerbate the clumping of alpha-synuclein in the brains of older mice. The findings add to a growing body of evidence which links gut health to Parkinson's disease.
A new analysis of medical evidence of domestic mass shooters in the US reveals the majority of those who commit mass shootings have underlying and untreated mental health conditions.
A new deep neural network can accurately predict a healthy person's brain age based on EEG data collected from a sleep study.
As novel visual patterns become familiar, stark changes occur in the visual cortex. Gamma rhythms give way to low-wave beta waves, and the neural activity switches from PV neurons in favor of inhibitory SOM neurons.
A new study reveals sex differences in the way those with alcohol use disorder process facial emotions. Men with AUD showed greater activation in frontal brain areas when processing facial emotions. The increased activation was not seen in women with AUD.
Insomnia experienced in childhood that continues into adulthood is a strong predictor of mood and anxiety disorders, a new study reports. Persistent insomnia from childhood was associated with a 2.8% increased risk of internalizing disorders in adulthood.
People with hyperphantasia, the ability to visualize vividly, have stronger connections between their visual brain network and decision-making networks. By contrast, those with aphantasia, an inability to visualize, have weaker connections between the brain regions.
