In a new paper published in FASEB Journal* by Rhonda Patrick, PhD and Bruce Ames, PhD of Children’s Hospital Oakland Research Institute (CHORI), serotonin is explained as the possible missing link tying together why vitamin D and marine omega-3 fatty acids might ameliorate the symptoms associated with a broad array of brain disorders.

What is happening in the brain of an actor reciting Hamlet’s “to be or not to be” soliloquy or of the person next to you at lunch saying, “Please pass the salt”? For 150 years, scientists have known that a brain region called Broca’s area plays a key role in speech production, but exactly what it does and how it does it have been a mystery.
Children born with a DNA abnormality on chromosome 16 already linked to neurodevelopmental problems show measurable delays in processing sound and language, says a study team of radiologists and psychologists.
An international team of scientists, led by researchers at the University of California, San Diego School of Medicine, has identified the microtubule-associated protein tau (MAPT) gene as increasing the risk for developing Alzheimer’s disease (AD). The MAPT gene encodes the tau protein, which is involved with a number of neurodegenerative disorders, including Parkinson’s disease and AD. These findings provide novel insight into Alzheimer’s neurodegeneration, possibly opening the door for improved clinical diagnosis and treatment.
The science behind many anti-depressant medications appears to be backwards, say the authors of a paper that challenges the prevailing ideas about the nature of depression and some of the world’s most commonly prescribed medications.
Monkeys are notoriously curious, and new research has quantified just how eager they are to gain new information, even if there are not immediate benefits. The findings offer insights into how a certain part of the brain shared by monkeys and humans plays a role in decision making, and perhaps even in some disorders and addictions in humans.
A new tool developed at the Howard Hughes Medical Institute's Janelia Research Campus lets scientists shine a light on an animal's brain to permanently mark neurons that are active at a particular time. The tool -- a fluorescent protein called CaMPARI that was developed at Janelia -- converts from green to red when calcium floods a nerve cell after the cell fires. The permanent mark frees scientists from the need to focus a microscope on the right cells at the right time to observe neuronal activity.
Scientists from the Florida campus of The Scripps Research Institute have for the first time discovered a killing mechanism that could underpin a range of the most intractable neurodegenerative diseases such as Alzheimer’s, Parkinson’s and ALS.
Experts have warned for years that insufficient sleep can lead to weight gain. A new Penn Medicine study found that not only do we consume more food following a night of total sleep deprivation, but we also we consume more fat and less carbohydrates and a region of the brain known as the salience network is what may lead us to eat more fat. The new findings are published in Scientific Reports.
Stem cell transplants may be more effective than the drug mitoxantrone for people with severe cases of multiple sclerosis (MS), according to a new study published in the February 11, 2015, online issue of Neurology®, the medical journal of the American Academy of Neurology.
A team of Stony Brook University researchers have identified fatty acid binding proteins (FABPs) as intracellular transporters for two ingredients in marijuana, THC and CBD (cannabidiol). The finding, published early online in the Journal of Biological Chemistry, is significant because it helps explain how CBD works within the cells. Recent clinical findings have shown that CBD may help reduce seizures and could be a potential new medicine to treat pediatric treatment-resistant epilepsy.
In a study with chronic adolescent and adult meth users in South Korea, MRI brain scans showed decreased thickness in the gray matter of younger users’ frontal cortex. Adult brains showed less damage.
Researchers have reversed some of the symptoms of Alzheimer’s disease in mice using magnetic resonance (MR) imaging-guided focused ultrasound.

Finally, an international team of researchers figured out its recipe: a toxin that permanently activates a crucial type of nerve cell protein, preventing the cells from resetting and causing deadly seizures in prey.
