New Computer Neural Networks Can Visually Identify as Well as the Primate Brain

A new study from MIT neuroscientists shows that the newest computer neural networks can identify visual objects as well as the primate brain. For decades, neuroscientists have been trying to design computer networks that can mimic visual skills such as recognizing objects, which the human brain does very accurately and quickly. Until now, no computer […]

Neuroscientists Reveal Fundamental Discovery about Cortical Neurons

Neuroscientists from the Picower Institute for Learning and Memory uncover a fundamental discovery about cortical neurons, showing that inhibitory neuron functionality is not an immutable property of cortical cells, but a consequence of more complex network dynamics. The two major types of neuron in the brain’s cerebral cortex are connected by intricate cortical circuits that […]

Men and Women Respond Differently to Cigarettes

New research from Yale University shows that men and women respond to cigarettes differently, demonstrating for the first time that smoking-induced dopamine activation occurs in a different brain region and much faster in nicotine-dependent men than women. Yale researchers using a new brain imaging analysis method have confirmed that smoking cigarettes activates a dopamine-driven pleasure […]

Proper Copper Levels Essential to Spontaneous Neural Activity

A new study from the Berkeley Lab reveals that proper copper levels are essential to the health of a brain at rest and suggests that mismanagement of copper in the brain linked to Alzheimer’s and other neurological disorders can also contribute to misregulation of signaling in cell−to-cell communications. In recent years it has been established […]

Brain Stimulation Can Restore Consciousness after a Seizure

In a newly published study, neurologists from Yale University have reawakened rats after seizures by stimulating parts of the brain involved in conscious awareness. The research may lead to treatments for individuals with epilepsy. Loss of consciousness is a common and dangerous side effect of epileptic seizures. A study published this week in the journal […]

White Matter Changes Allow Older Brains to Learn

New research from Brown University shows that older people can learn a visual task just as well as younger ones, revealing that a significant change in the white matter of the brain takes place when the older subjects learn. Providence, Rhode Island (Brown University) — A widely presumed problem of aging is that the brain […]

Calorie-Restricting Diets Slow Aging

Neuroscientists show that calorie-reduced diets stop the normal rise and fall in activity levels of close to 900 different genes linked to aging and memory formation in mice. The adage ‘you are what you eat’ has been around for years. Now, important new research provides another reason to be careful with your calories. In a […]

Decoy Drug Allows Brain to Form New Connections

New research from Stanford Bio-X scientists shows that the brains of adult mice are able to form new synapses by disabling the function of a single protein for as little as a week. This research has the potential to help adults recover from stroke and forms of blindness or to prevent the loss of connections […]

New Approach Could Kill Tumor Cells in the Brain More Effectively

New research shows that delivering chemotherapy directly into the brain cavity may kill tumor cells in the brain more effectively and avoid side effects. Every year, about 100,000 Americans are diagnosed with brain tumors that have spread from elsewhere in the body. These tumors, known as metastases, are usually treated with surgery followed by chemotherapy, […]

Dietary Cocoa Flavanols Reverse Age-Related Memory Decline in Healthy Older Adults

A new study from Columbia University Medical Center shows that dietary cocoa flavanols reverse age-related memory decline in healthy older adults. New York, New York — Dietary cocoa flavanols—naturally occurring bioactives found in cocoa—reversed age-related memory decline in healthy older adults, according to a study led by Columbia University Medical Center (CUMC) scientists. The study, […]

Researchers Discover Mechanism that Repairs Brain after Stroke

Working with mice, researchers from Lund University and the Karolinska Institute have discovered a previously unknown mechanism through which the brain produces new nerve cells after a stroke. The findings have been published in the journal Science. A stroke is caused by a blood clot blocking a blood vessel in the brain, which leads to […]

New MRI Technique Detects Evidence of Cognitive Decline

A new study shows that a noninvasive arterial spin labeling MRI can detect signs of cognitive decline in the brain even before symptoms appear, finding that patients who showed reduced brain perfusion at their initial exams exhibited cognitive decline at follow-up 18 months later. Oak Brook, Illinois — A magnetic resonance imaging (MRI) technique can […]

Study Shows Multitasking May Change Brain Structure

New research from the University of Sussex shows that people who frequently use several media devices at the same time have lower grey-matter density in one particular region of the brain compared to those who use just one device occasionally. Simultaneously using mobile phones, laptops and other media devices could be changing the structure of […]

Eye of Zebrafish Larva Distinguishes Between Prey and Predator

A new study from the Max Planck Institute for Medical Research reveals how the eye of a zebrafish larva can already distinguish between prey and predator. Red or green? Small or large? Fast or slow? Humans and animals rely on their visual organs to classify objects in their environment. Decisions about how we best respond […]

Brain Structure Could Predict Risky Behavior

New research shows that brain structure may predict risky behavior, revealing that those with a larger volume in a particular part of the parietal cortex were willing to take more risks than those with less volume in this part of the brain. Some people avoid risks at all costs, while others will put their wealth, […]
