Published Hearing relaxing words in your sleep slows your heart down (via sciencedaily.com) Original source
Researchers have investigated whether the body is truly disconnected from the external world during sleep. To do so, they focused on how heartbeat changes when we hear different words during sleep. They found that relaxing words slowed down cardiac activity as a reflection of deeper sleep and in comparison to neutral words that did not have such a slowing effect. This discovery sheds new light on brain-heart interactions during sleep.
Published Cracking the code of neurodegeneration: New model identifies potential therapeutic target (via sciencedaily.com) Original source
Scientists have developed an innovative neural cell culture model, shedding light on the intricate mechanisms underlying neurodegeneration. Their research pinpointed a misbehaving protein as a promising therapeutic target in the treatment of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD).
Published Uncovering anxiety: Scientists identify causative pathway and potential cures (via sciencedaily.com) Original source
Quick-acting targeted therapies with minimal side effects are an urgent need for the treatment of anxiety-related disorders. While delta opioid receptor (DOP) agonists have shown 'anxiolytic' or anxiety-reducing effects, their mechanism of action is not well-understood. A new study highlights the role of specific neuronal circuits in the brain involved in the development of anxiety, and distinct mechanisms of action of the therapeutic DOP agonist -- KNT-127.
Published Air pollution linked to more signs of Alzheimer's in brain (via sciencedaily.com) Original source
People with higher exposure to traffic-related air pollution were more likely to have high amounts of amyloid plaques in their brains associated with Alzheimer's disease after death, according to a new study. Researchers looked at fine particulate matter, PM2.5, which consists of pollutant particles of less than 2.5 microns in diameter suspended in air.
Published How does the brain make decisions? (via sciencedaily.com) Original source
Mouse study provides insights into communication between neurons during decision-making.
Published Possible trigger for autoimmune diseases discovered : B cells teach T cells which targets must not be attacked (via sciencedaily.com) Original source
Immune cells must learn not to attack the body itself. A team of researchers has discovered a previously unknown mechanism behind this: other immune cells, the B cells, contribute to the 'training' of the T cells in the thymus gland. If this process fails, autoimmune diseases can develop. The study confirms this for Neuromyelitis optica, a disease similar to Multiple Sclerosis. Other autoimmune diseases may be linked to the failure of this new mechanism as well.
Published Fixing rogue brain cells may hold key to preventing neurodegeneration (via sciencedaily.com) Original source
Scientists have identified a new therapeutic approach for combating neurodegenerative diseases, offering hope of improved treatments for Alzheimer's disease, Parkinson's disease, Vanishing White Matter disease and multiple sclerosis, among others.
Published Mapping potential pathways to MND treatment (via sciencedaily.com) Original source
Researchers have mapped out the proteins implicated in the early stages of motor neurone disease (MND). They have developed a longitudinal map of the proteins involved in MND across the trajectory of the disease, identifying potential therapeutic pathways for further investigation.
Published Modifying brain molecule relaxin-3 can potentially reduce side effects in treating anxiety, depression and more (via sciencedaily.com) Original source
A team of researchers has found a potential way to treat conditions like depression and anxiety with fewer side effects.
Published Blocking key protein may halt progression of Alzheimer's disease (via sciencedaily.com) Original source
Researchers have found that inhibiting a key protein can stop the destruction of synapses and dendritic spines commonly seen in Alzheimer's disease.
Published Stress during pregnancy can lead to early maturation of first-born daughters (via sciencedaily.com) Original source
Researchers have found a correlation between early signs of adrenal puberty in first-born daughters and their mothers' having experienced high levels of prenatal stress. They did not find the same result in boys or daughters who were not first-born.
Published To boost a preschooler's language skills, consider reminiscing (via sciencedaily.com) Original source
Book sharing is a popular way parents engage young children in conversation. However, not all parents are comfortable with book sharing and not all children like having books read to them. Research provides an alternative. To boost the quality of a preschooler's language experience and skills, consider reminiscing with them. Findings show reminiscing is very good at eliciting high quality speech from parents, and in many ways, is just as good as book sharing (wordless picture books).
Published How parents can help prevent the development of ADHD symptoms (via sciencedaily.com) Original source
Parents of young children with an excitable or exuberant temperament could adapt their parenting style to help moderate their child's potential development of Attention Deficit/Hyperactivity Disorder (ADHD), according to a new study.
Published Exposure to Agent Orange damages brain tissue in ways similar to Alzheimer's disease (via sciencedaily.com) Original source
Agent Orange, an herbicide used during the Vietnam War, is a known toxin with wide-ranging health effects. Even though Agent Orange has not been used for decades, there is increasing interest in its effects on the brain health of aging veterans. A new study reveals the mechanisms by which Agent Orange affects the brain and how those processes can lead to neurodegenerative diseases. The research shows that exposures to Agent Orange herbicidal chemicals damage frontal lobe brain tissue of laboratory rats with molecular and biochemical abnormalities that are similar to those found in early-stage Alzheimer's disease.
Published Neuronal insights: Flash and freeze-fracture (via sciencedaily.com) Original source
Fear and addiction exert significant influence within society. Managing them is often challenging, as they are driven by intricate neuronal circuits in our brains. Understanding the underlying molecular mechanisms is crucial to intervene when these processes malfunction. The novel 'Flash and Freeze-fracture' technique provides a unique glimpse into the respective brain region.
Published Neural prosthetic device can help humans restore memory (via sciencedaily.com) Original source
A team of scientists have demonstrated the first successful use of a neural prosthetic device to recall specific memories.
Published Are you depressed? Scents might help (via sciencedaily.com) Original source
Smelling a familiar scent can help depressed individuals recall specific autobiographical memories and potentially assist in their recovery.
Published Immune genes are altered in Alzheimer's patients' blood (via sciencedaily.com) Original source
A new study has found the immune system in the blood of Alzheimer's patients is epigenetically altered. That means the patients' behavior or environment has caused changes that affect the way their genes work. Many of these altered immune genes are the same ones that increase an individual's risk for Alzheimer's. Scientists now theorize the cause could be a previous viral infection, environmental pollutants or other lifestyle factors and behaviors.
Published How emotions affect word retrieval in people with aphasia (via sciencedaily.com) Original source
People with aphasia have more trouble coming up with words they want to use when they're prompted by images and words that carry negative emotional meaning, new research suggests.
