A new technique that uses ultrafast fMRI is able to capture brain activity at sub-second levels. The technique allows for real-time monitoring of the brain under stimulation conditions.
The "love hormone" oxytocin may not play as critical a role in bonding as previously believed. Removing the oxytocin receptor in animal models still resulted in monogamous mating, attachment, and parental bonding behaviors, although females without the receptor produced milk in smaller quantities. Findings reveal parenting and bonding aren't purely dictated by oxytocin receptors.
A newly developed blood-based test reveals changes in hippocampal neurogenesis up to 3.5 years before a clinical diagnosis of Alzheimer's disease.
People with behavioral variant frontotemporal dementia (bvFTD) exhibit behaviors that are considered socially unacceptable. While there is no current cure for FTD, researchers are finding methods to help inhibit some of the negative behaviors associated with FTD. A new study reports impulsivity and negative behaviors are greatly reduced in those with bvFTD when the patient is focused on a task.
Researchers identified a specific type of cell that sits on top of the brain's smallest blood vessels that sense when their region of the brain is in need of energy.
Science research articles covering neurology, brain cancer, traumatic brain injuries, neurosurgery, neuroanatomy, brain research and neurological disorders.
Long-term, continuous marriage from mid-life to old age is associated with a lower risk of developing dementia.
Study provides experimental evidence of an alternative binding site on amyloid-beta aggregates. The discovery opens the door to the development of new therapies for Alzheimer's disease.
Adopting a healthy lifestyle, in particular, a healthy diet was associated with a slower than average decline in memory over ten years in older adults, even those with the APOE4 Alzheimer's associated genetic variant.
Lower levels of serine and glycine were associated with a higher risk of neuropathic pain in mouse models of diabetes. Supplementing the diets of the mice with serine reduced symptoms of neuropathy. Researchers say the findings provide a new way in which to identify people at risk of diabetic neuropathy and a potential treatment option.
Exposure to drugs that target tauopathies extended survival, reduced neurodegenerative biomarkers, and functionally reduced aberrant behaviors in female mice, but not in males.
Science research articles cover psychology, depression, mental health, schizophrenia, mental disorders, happiness, stress, PTSD, autism, psychiatry and therapy.
Laughter doesn't only help bring people together, it can be great therapy for those suffering from depression, researchers report.
State-level legalization of recreational cannabis does not increase substance use disorder or encourage the use of other illicit drugs, a new study of twins reveals. Additionally, legalized recreational cannabis can reduce alcohol consumption.
Even small bouts of physical activity and exercise throughout the day can help to boost your mental well-being.
Parental stress is higher in parents who suffer from sleep disorders or have children with disordered sleeping.
Running can help some escape from their everyday stresses, however, some recreational runners show signs of exercise dependence. Exercise dependence could be the result of maladaptive escapism where one self-suppresses to avoid negative experiences. This can be detrimental to overall well-being.

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.
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.
Where and when grandparents and parents of children were born could contribute to an increased risk of ASD in their offspring.
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.
A new study links substance use disorder to specific personality traits and certain psychological disorders. Researchers found those who scored high for the personality trait of neuroticism and those with depression and anxiety were at greater risk of SUD.
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.
A new stem cell therapy approach eliminates established brain tumors and provides long-term immunity, training the immune system to prevent cancer from returning.
Autopsy tissue samples of 44 people who died of COVID-19 showed SAR-CoV-2, the virus responsible for coronavirus, spread throughout the body and to the brain, with traces of the virus lingering for 8 months.
