New Research Shows Fructose Alters Brain Genes, Can Lead to Disease

A new study by researchers at UCLA reveals that genes in the brain can be damaged by fructose, leading to diseases like diabetes, cardiovascular disease, Alzheimer’s disease and attention deficit hyperactivity disorder. A range of diseases — from diabetes to cardiovascular disease, and from Alzheimer’s disease to attention deficit hyperactivity disorder — are linked to […]

New Study Links Genes to Marijuana Dependence and Major Depression

A newly published genome-wide analysis of more than 14,000 individuals has identified several gene variants that increase risk of cannabis dependence. The analysis also suggests that the genetic risk for dependence on marijuana is associated with a higher inherited risk of major depression. The new study is published in the journal JAMA Psychiatry. The study […]

Stem Cell Innovation Could Treat Parkinson’s

A team of researchers from Rutgers and Stanford have created a new way to inject healthy human nerve cells into the brain that could someday help treat Parkinson’s disease and other devastating brain-related conditions that affect millions of people. The technology – a major innovation – involves converting adult tissue-derived stem cells into human neurons […]

Yale Scientists Track How Brain Routes Visual Signals

Newly published research from Yale’s Department of Neuroscience provides some clues to how cells in the visual cortex direct sensory information to different targets throughout the brain. Understanding how the brain manages to process the deluge of information about the outside world has been a daunting challenge. By imaging activity in the mouse brain, the […]

Gene for Behavioral State May be Linked to Autism

In a newly published study, neuroscientists from MIT reeval a gene that plays a critical role in controlling the switch between alternative behavioral states – which for humans include hunger and fullness, or sleep and wakefulness. This gene, which the researchers dubbed vps-50, helps to regulate neuropeptides — tiny proteins that carry messages between neurons […]

Researchers Identify Cells That Represent Feelings of Isolation

In a newly published study, MIT neuroscientists reveal how they identified a brain region that represents the feelings of loneliness. Humans, like all social animals, have a fundamental need for contact with others. This deeply ingrained instinct helps us to survive; it’s much easier to find food, shelter, and other necessities with a group than […]

Neurobiologists Characterize Nerve Cells That Detect Motion by Light Changes

In a newly published study, neurobiologists from the Max Planck Institute reveal that (in fruit flies) four classes of nerve cell are involved in calculating directionally selective signals. The ability to see the direction in which something is moving is vital for survival. Only in this way is it possible to avoid predators, capture prey […]

Scientists Identify Protein That Allows Brain Cells to Dampen Their Sensitivity

In a newly published study, neuroscientists from MIT identify a protein that allows brain cells to dampen their sensitivity. Strengthening and weakening the connections between neurons, known as synapses, is vital to the brain’s development and everyday function. One way that neurons weaken their synapses is by swallowing up receptors on their surfaces that normally […]

Hyperactive neurons may be culprit in Alzheimer’s

New research from Yale University shows that an increase in neuronal activity can spur the creation of plaques and toxic amyloid beta peptides, which are believed to trigger Alzheimer’s disease. A long-term reduction in neuronal activity reduces amyloid plaques associated with Alzheimer’s disease, Yale University researchers have found. The study, using mouse models of Alzheimer’s, […]

Football Increases Risk of Degenerative Disorder

Past evidence has shown that professional football players are susceptible to a progressive degenerative disease, chronic traumatic encephalopathy (CTE), which is caused by repetitive brain trauma. Now a new study from the Mayo Clinic reveals a significant and surprising amount of CTE in males who had participated in amateur contact sports in their youth. About […]

Newly Identified Mechanism Helps Strengthen Links between Neurons

Neuroscientists from MIT have identified a new mechanism that allows the brain to strengthen links between neurons. When the brain forms memories or learns a new task, it encodes the new information by tuning connections between neurons. MIT neuroscientists have discovered a novel mechanism that contributes to the strengthening of these connections, also called synapses. […]

Researchers Reprogram Neurons

A newly published study from Harvard biologists shows how neurons can be dramatically changed from one type into another from within the brain and how neighboring neurons recognize the reprogrammed cells as different and adapt by changing how they communicate with them. Building on earlier work in which they disproved neurobiology dogma by “reprogramming” neurons […]

Researchers Observe Signs of Synaptic Plasticity Emerging in a Living Brain

Using measurements of changes in neural activity in neurons of the inferior temporal cortex of mature nonhuman primates as they observed novel and familiar stimuli, neuroscientists have observed signs of synaptic plasticity emerging in a living brain while it accomplishes the feat of beholding and recognizing stimuli. From the first project David Sheinberg took on […]

MIT Neuroscientists Identify Brain Region That Holds Objects in Memory

Neuroscientists from MIT have identified the region of the brain that holds objects in memory until they are spotted. Imagine you are looking for your wallet on a cluttered desk. As you scan the area, you hold in your mind a mental picture of what your wallet looks like. MIT neuroscientists have now identified a […]

New Discovery Could Lead to Better Recovery After Stroke

Scientists from UCLA have identified a molecule (GDF10) that signals brain tissue to form new connections after a stroke. The finding could eventually lead to a new treatment to promote brain repair and functional recovery in people who have suffered a stroke, which is the leading cause of serious long-term disability in adults. The five-year […]

Rare Genetic Mutation Extends Cancer Survival

A new study from Yale University reveals that patients with the rare ALK mutation are living an average of four years, compared to typical patients that die of NSCLC within seven months. Most patients with non-small cell lung cancer (NSCLC) that has metastasized to the brain have a dire prognosis. But Yale researchers have identified […]

Functional Connectome Fingerprinting Identifying Individuals Using Patterns of Brain Connectivity

A newly published study from Yale University reveals that a person’s brain activity appears to be as unique as his or her fingerprints. These brain “connectivity profiles” alone allow researchers to identify individuals from the fMRI images of brain activity of more than 100 people, according to the study published October 12 in the journal […]
