New Model for Solving Novel Problems Uses Mental Map

How do we make decisions about a situation we have not encountered before? New work shows that we can solve abstract problems in the same way that we can find a novel route between two known ...

Struggling to Learn a New Language? Blame It on Your Stable Brain

A study in patients with epilepsy is helping researchers understand how the brain manages the task of learning a new language while retaining our mother tongue. The study sheds light on the age-old ...

Brain-Inspired Memory Device

Many electronic devices today are dependent on semiconductor logic circuits based on switches hard-wired to perform predefined logic functions. Physicists have developed a novel molecular memristor, ...

Beyond Dopamine: New Reward Circuitry Discovered

The key to overcoming addictions and psychiatric disorders lives deep inside the netherworld of our brains and the circuitry that causes us to feel good. Just like space, this region of the brain ...

Vision: Novel Approach Reverses Amblyopia in Animals

By temporarily suspending retinal activity in the non-amblyopic eye of animal models, neuroscientists restrengthened the visual response in the amblyopic eye, even at ages after the critical period ...

Do Genetics Control Who Our Friends Are? It Seems So With Mice

Have you ever met someone you instantly liked, or at other times, someone who you knew immediately that you did not want to be friends with, although you did not know why? Now, a new study suggests ...

Machine Learning Algorithm Revolutionizes How Scientists Study Behavior

B-SOiD is an open source, unsupervised algorithm that can discover and identify behaviors without user ...

Fighting Brain Cancer at Its Root

Researchers identify proteins that drive cancer stem cells. Targeting and suppressing a particular protein called galectin1 could provide a more effective treatment for glioblastoma, in combination ...

Voices of Reason? Study Links Acoustic Correlations, Gender to Vocal Appeal

What makes a voice attractive? The question is the subject of broad interest, with far-reaching implications in our personal lives, the workplace, and society. Scientists describe research that ...

In an effort to understand how the internal state of the body influences the brain's decision-making processes, scientists analyzed the data from a previous study pre-clinical study. They found ...

At Least 80% of Opioid Overdoses Aren’t Fatal, but How Do They Affect the Brain?

Scientists still know little about how opioid overdoses affect the brain and cognition. Researchers found that, while evidence exists to support a link between overdose, cognitive impairment and ...

Insights Into How a Stroke Affects Reading Could Help With Rehabilitation

Researchers, looking at the ability of people to sound out words after a stroke, found that knowing which region of the brain was impacted by the stroke could have important implications for helping ...

Neurons in Visual Cortex of the Brain ‘drift’ Over Time

New research reveals that neurons in the visual cortex -- the part of the brain that processes visual stimuli -- change their responses to the same stimulus over time. Although other studies have ...

Old Habit-Controlling Neurons May Also Help the Brain Learn New Tricks

In a study of rodents, scientists discovered that a part of the brain traditionally thought to control typing the old sequence may also play a critical role in learning the new one. The results ...

Your Sense of Smell May Be the Key to a Balanced Diet

When we smell food, we are more likely to eat -- but new findings suggest eating food also impacts our sense of smell, which could bias what we eat next. Imaging shows that brain's response to ...

Altered Functional Brain Network Connectivity Associated With Symptoms of Post-Traumatic Stress in COVID-19 Survivors, Study Shows

COVID-19 survivors report significantly higher symptoms of post-traumatic stress, and these symptoms are associated with changes to the brain's connectivity, according to a new ...

Brain Tissue Inflammation Is Key to Alzheimer's Disease Progression

Neuroinflammation is the key driver of the spread of pathologically misfolded proteins in the brain and causes cognitive impairment in patients with Alzheimer's disease, researchers reveal in a ...

Restoring 'Chaperone' Protein May Prevent Plaque Build-Up in Alzheimer’s

Researchers have shown how restoring levels of the protein DAXX and a large group of similar proteins prevents the misfolding of the rogue proteins known to drive Alzheimer's and other ...

Research Reveals How Subtle Changes in a microRNA May Lead to ALS

This latest research on microRNAs (miRNAs), regulatory molecules that act like brakes to reduce the production of proteins, has implications for studying and treating the underlying causes of ...

A Mechanism Underlying Most Common Cause of Epileptic Seizures Revealed

An interdisciplinary team studying neurogenetics, neural networks, and neurophysiology has revealed how dysfunctions in even a small percentage of cells can cause disorder across the entire ...
