Researchers have identified a specific neural circuit and neuropeptide responsible for relaying the sensation of a pleasant touch from the skin to the brain.
Obstructive sleep apnea may impact your behavior when driving, a new study reports. People with sleep apnea who experienced eight additional disruptions in breathing per hour had a 27% increased risk of making dangerous driving moves, such as speeding, hard breaking , or accelerating suddenly.
Infants born to mothers living in poverty have smaller volumes of gray and white matter across the entire brain. Additionally, babies born to mothers who live in high crime areas showed differences in brain activity to those whose mothers lived in safer areas. Those born to mothers who experienced crime had weaker neural connections between brain areas that control and process emotions. Maternal stress, researchers say, could be a main factor in the differences in neuroanatomy and brain connectivity.
A number of patients who contracted COVID-19 in the early months of the pandemic reported symptoms of neuropathy, including pain, tingling sensations, and numbness that lasted up to three months after recovery. The findings suggest COVID-19 may have lingering effects on peripheral nerves.
Alpha2-NKA, a protein that drives toxicity in astrocytes, was discovered in higher levels of brain samples from people who died of PSP, Alzheimer's and other tau-related neurodegenerative disorders. Treatment with an FDA-approved drug called digoxin may suppress the inflamed astrocytes and halt disease progression for those with tauopathy disorders.
Asthma causes T cells to induce lung inflammation but prevents the growth of brain tumors. Reprogramming T cells in patients with brain cancer to act like T cells in those with asthma may help to curb the growth of tumors.
Students who consistently sleep the optimal eight hours per night perform better on tests and report higher personal satisfaction than their peers who have more disrupted sleep patterns.
Genetic risk for mental health disorders is associated with brain structure and the occurrence of psychosis-like experiences in children between 9 and 10 years of age.
