Markers of fear recall differ between sexes, but in a hormone-dependent manner

A new study shows that markers of fear recall differ between men and women, but in a hormone-dependent manner.

Study demonstrates profound anhedonia in people with frontotemporal dementia

People with early-onset dementia are often mistaken for having depression and now Australian research has discovered the cause: a profound loss of ability to experience pleasure - for example a delicious meal or beautiful sunset - related to degeneration of 'hedonic hotspots' in the brain where pleasure mechanisms are concentrated.

Suppressing facial expressions may be useful in certain contexts, shows study

How do our facial expressions in response to seeing others in pain influence how we see and feel their pain? There are many situations where it may be helpful to suppress our emotional responses to the pain of others.

Signal detection theory can be used to better understand cognitive fatigue

A team of New Jersey researchers has shown that changes in perceptual certainty and response bias, two central metrics of signal detection theory (SDT), correlate with changes in cognitive fatigue.

Eco-bio-developmental model of emergent literacy helps identify risk factors of reading difficulties

Researchers at Cincinnati Children's Hospital Medical Center have developed a new framework for different factors influencing how a child's brain is "wired" to learn to read before kindergarten.

Anabolic-androgenic steroids can have deleterious effects on the brain

Anabolic-androgenic steroids (AAS), a synthetic version of the male sex hormone testosterone, are sometimes used as a medical treatment for hormone imbalance. But the vast majority of AAS is used to enhance athletic performance or build muscle because when paired with strength training.

Sargramostim drug can also improve memory in people with mild-to-moderate Alzheimer's disease

A new study suggests that Sargramostim, a medication often used to boost white blood cells after cancer treatments, is also effective in treating and improving memory in people with mild-to-moderate Alzheimer's disease.

Communication between the brain’s auditory and reward circuits underpins music-induced pleasure

Communication between the brain’s auditory and reward circuits is the reason why humans find music rewarding, according to new research published in JNeurosci.

Study reveals the incidence of structural abnormalities in the developing brain

A large study of brain MRI scans from 11,679 nine- and ten-year-old children reviewed by UC San Francisco neuroradiologists identified potentially life-threatening conditions in 1 in 500 children, and more minor but possibly clinically significant brain abnormalities in 1 out of 25 children.

Children at high risk of dyslexia face difficulty in learning nonsensical words

Researchers at Aalto University and the Niilo Mäki Institute have used neuroimaging to pinpoint where the brain activates - or doesn't activate - among children identified as having a high risk of dyslexia. Magnetoencephalography (MEG) has rarely been used to study the reading disorder in children.

Study shows evidence-based interventions can improve infant brain health

In the world of neurodevelopment, one thing is clear: the earlier the intervention the better. Infancy is a critical time in brain development, and neuroscientists are increasingly identifying factors that can negatively impact cognition and ones that can improve cognition early in life.

Executive control differences in autism may be the result of a unique approach

A new study by UC Davis MIND Institute researchers suggests that executive control differences in autism spectrum disorder (ASD) may be the result of a unique approach, rather than an impairment.

Study examines central nervous system imaging manifestations of COVID-19 in children

While neurological complications of COVID-19 in children are rare, in contrast to adults, an international expert review of positive neuroimaging findings in children with acute and post-infectious COVID-19 found that the most common abnormalities resembled immune-mediated patterns of disease involving the brain, spine, and nerves.

Bone marrow cell injections may lead to reduction in brain injury after stroke

Results of a clinical trial released in STEM CELLS Translational Medicine provide evidence that treating patients with an injection of bone marrow cells may lead to a reduction in brain injury after a stroke.

Functional connectivity in brain's fatigue network changes in response to cognitive fatigue

Kessler Foundation researchers have demonstrated changes in the functional connectivity within the 'fatigue network' in response to cognitive fatigue.

Cincinnati Children's scientists receive grant to advance research on air pollution and mental health

Scientists at Cincinnati Children's just received a 5-year grant totaling $5.3 million from the National Institute of Environmental Health Sciences to advance research into the relationship between air pollution and mental health in children and adolescents.

Study provides detailed insight into neural mechanisms underlying placebo effects

A large proportion of the benefit that a person gets from taking a real drug or receiving a treatment to alleviate pain is due to an individual's mindset, not to the drug itself.

Review highlights symptoms, effects and probable causes of tinnitus

According to research conducted by JCDR, at least 9 out of 10 adults suffer from low health literacy in India. Health literacy is a vital aspect of any nation's growth - be it developed, underdeveloped, or a developing nation.

Researchers identify a neural pathway critical to correcting behavioral errors

Mount Sinai researchers have identified a neural pathway through which the brain detects errors and guides subsequent behavioral improvement. This process, called cognitive control, is frequently dysregulated in a wide range of psychiatric disorders.

HIV-positive people with severe immunosuppression, APOE4 gene may have increased risk for dementia

People living with the human immunodeficiency virus (HIV) who have a history of severe immunosuppression and at least one copy of the Alzheimer's disease-related gene variant APOE4, might see a compounded adverse effect on the circuitry that impacts memory.
