Neuroscience Research Articles
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.
Study offers promising insight into how technology can aid in early math skills and can be used to close gaps in early childhood learning.
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.
People who frequently take sleeping medications are 79% more likely to develop dementia than those who never use sleeping pills to aid their rest.
Neuroimaging reveals partisanship-dependent differences in brain stimulation when people are exposed to political messaging from either their own or opposing political sides.
Science research articles covering neurology, brain cancer, traumatic brain injuries, neurosurgery, neuroanatomy, brain research and neurological disorders.
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.
In women, parts of the default mode network responsible for memory retrieval and recollection, and spatial cognition were more likely to be connected to the overall DMN network. The patterns of connectivity correlated with brain structures associated with short-term memory problems resembled alterations seen in preclinical Alzheimer's disease.
The Orai1 class of calcium channels regulates sex differences in the functioning of immune cells associated with neuroinflammation and neuropathic pain.
Chronic pain in mice activates Tiam1 in pyramidal neurons in the anterior cingulate cortex, increasing the number of dendritic spines and inducing synaptic plasticity. Ketamine's antidepressant effect in chronic pain is mediated by the drug blocking Tiam1-dependent maladaptive synaptic plasticity in ACC neurons.
Adding a splash of milk to your cup of coffee can have anti-inflammatory effects, a new study reports. Researchers say the combination of polyphenols and proteins doubles anti-inflammatory properties in immune cells.
Science research articles cover psychology, depression, mental health, schizophrenia, mental disorders, happiness, stress, PTSD, autism, psychiatry and therapy.
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.
Phobic and agoraphobic symptoms are common in those with epilepsy and result in a poorer quality of life.
The state of gratitude lowers systolic blood pressure response through stress-testing experiences, demonstrating that gratitude has a unique buffering effect against both reactions to and recovery from psychological stress.
Perspective-taking and empathy not only reduce the temptation to cheat on a partner, but they also help protect against other relationship-destroying behaviors.

These are the most viewed articles from all of Neuroscience News over the last 30 days and includes all categories such as neuroscience, AI, psychology, neurology, robotics and neurotech.
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.
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.
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.
By inhibiting NMDA receptors, ketamine increases noise to gamma frequencies in one layer of the thalamic nucleus and one lay of the somatosensory cortex. Findings suggest psychosis may be triggered by an increase in background noise impairing thalamocortical neurons which may be caused by a malfunction in NMDA receptors affecting the balance of inhibition and excitation in the brain.
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.
