Meta-analysis reveals those who have visual impairments or are blind have a higher risk of mortality compared to peers with better vision. The study found mortality risk was 29% higher in those with mild visual impairment and rose to 89% higher for those with severe visual impairments.
Following exposure to visual stimuli, the neurons activated by the stimuli remain more active during subsequent sleep. Sleep is vital for these neurons to connect an emotional or fearful memory to a sensory event.
The prevalence of borderline personality disorder diagnosis was almost double in sexual minorities compared to heterosexuals. Researchers propose the higher numbers could be a result of the bias against sexual minorities of those diagnosing the disorder.
People who use cannabis as a form of pain management report sleeplessness, nausea, and changes in mood or behavior when they go a significant time without using the drug.
Researchers have identified a novel neural network in fruit flies that converts external stimuli of varying intensity into decisions about whether to act.
Glioblastoma brain cancer cells that are more resistant to radiation therapy have higher levels of purines. Reducing the level of purines made the cancer cells more sensitive to radiation.
Obesity risk in teens appears to be associated with stronger connectivity within and between regions of the brain implicated in determining the salience of stimuli. This may have implications for reward processing. Researchers report executive control efforts in the brain decrease when salience and reward-processing regions are engaged in teens with obesity.
Researchers reduced the power requirements of neural interfaces while improving their accuracy by tuning into a subset of brain waves.
Patients with severe COVID-19 infections have higher blood levels of neutrophil extracellular traps (NETs), which produce NETosis, an inflammatory type of neutrophil cell death. Researchers believe the NETs may be relevant to numerous aspects of novel coronavirus as thrombosis and inflammation are hallmarks of the severe infection.
People who experience a spinal cord injury have an increased risk of developing a mental health disorder, a new study reports. Those with SCI had higher instances of anxiety, depression, and psychological multimorbidity than those who had not experienced a debilitating injury.
