Neuroscience Research Articles
Study reveals heightened activity in the amygdala in response to seeing surprised or neutral facial expressions could be a biomarker for a risk of developing PTSD following trauma.
A genetic predisposition to oral health problems increased the risk of white matter hyperintensities and was associated with a 43% increase in microstructural damage in the brain. The study adds to the growing body of evidence connecting poor oral health to an increased risk of neurological disorders.
Thalamic inputs into superficial layers of the cerebral cortex are both rare and weak, yet surprisingly diverse in their distribution patterns. However, they are reliable and efficient representatives of information.
6 to 9-month-old babies can form memories of masked faces and recognize the faces when the mask is removed.
Using data from Twitter, researchers were able to determine specific events and locations within cities that were associated with different emotions. Train stations and transportation sites were associated with less joy and more disgust, while hotels and restaurants were linked to a greater expression of joy.
Science research articles covering neurology, brain cancer, traumatic brain injuries, neurosurgery, neuroanatomy, brain research and neurological disorders.
Loneliness and a lack of social support contribute to a higher risk of developing Alzheimer's disease or other dementias. The findings add to the growing body of evidence linking social isolation to Alzheimer's disease.
Migraine diagnosis in women prior to pregnancy was linked with an increased risk of complications during pregnancy including preeclampsia, gestational hypertension, and an increased risk of pre-term birth.
High consumption of ultra-processed foods, including soda, chips, and some white bread products, was associated with an increased risk of developing and dying from certain kinds of cancer, including brain cancer.
Researchers discovered a correlation between obesity-related neurodegeneration and Alzheimer's disease pathology. Losing weight, they say, can slow age-related cognitive decline and reduce the risk of developing Alzheimer's.
CRISPR gene editing created the G795A amino acid which was introduced to microglia derived from human stem cells. Researchers were able to transplant the donor microglia immune cells into humanized rodent models while administering an FDA-approved cancer drug called pexidartinib. The inclusion of the amino acid cause the donated microglia to thrive and resist the drug, while the host microglia died. The findings open the door for new methods of using microglia to treat a range of neurodegenerative disorders.
Science research articles cover psychology, depression, mental health, schizophrenia, mental disorders, happiness, stress, PTSD, autism, psychiatry and therapy.
Having a sense of purpose in life decreases alcohol consumption and binge drinking temptation in some social drinkers.
Beta-blockers, a class of drugs commonly used to treat hypertension and cardiovascular disorders, appear to reduce aggressive and violent behaviors, and can reduce suicidal behaviors.
Neuroimaging reveals partisanship-dependent differences in brain stimulation when people are exposed to political messaging from either their own or opposing political sides.
Study reveals an association between depression and other mental health problems and an increased risk of cardiovascular disease in younger people.
MAP4343, an experimental antidepressant compound reversed alcohol intake in rat models of alcohol use disorder. The findings pave the way for utilizing the compound for the treatment of AUD in humans.

Levodopa, a drug commonly prescribed for the treatment of Parkinson's disease that increases dopamine in the brain was found to reverse the effects of neuroinflammation on the reward system and improve symptoms associated with depression.
Brain levels of FAAH, an enzyme that degrades a neurotransmitter that activates the cannabinoid 1 receptor, may contribute to the maintenance of excessive drinking and susceptibility to alcohol use disorder.
Anhedonia and depression arise when POMC neurons in the arcuate nucleus of the hypothalamus become hyperactive as a result of chronic stress. Reducing the activity also reduces feelings of depression and loss of pleasure.
Where and when grandparents and parents of children were born could contribute to an increased risk of ASD in their offspring.
Rilmenidine, a drug commonly prescribed to help treat hypertension can help slow the effects of aging and extend lifespan, a new study reports.
Some patients diagnosed with behavioral-variant frontotemporal dementia (bv-FTD) may instead be suffering from a cerebrospinal fluid leak that leads to brain sagging.
An ADHD diagnosis is more predictive of poor mental health outcomes than other neurodevelopmental disorders such as autism.
SSRI antidepressants can make users less sensitive to rewards, resulting in emotional blunting many users experience. The findings provide new evidence for the role serotonin plays in reinforcement learning.
A new stem cell therapy approach eliminates established brain tumors and provides long-term immunity, training the immune system to prevent cancer from returning.
Adding 57g of almonds to the diet every day for a month increases levels of the beneficial fat, 12,13-DiHOME in blood samples immediately after a session of intense exercise.
