In a study published November 7 in the journal Cell Reports Medicine, researchers from Tufts University School of Medicine and Vanderbilt University School of Medicine show that people with schizophrenia generate distinct neural patterns when asked to make decisions based on conflicting information. The work offers one of the first biological tests to assess whether someone is prone to inflexible thinking and, by monitoring changes in these patterns, a new way to measure whether treatments are working.

Complex Sound Patterns are recognized by newborn brains
A team of researchers, including psycholinguist Jutta Mueller from the University of Vienna, has discovered that newborns are capable of learning complex sound sequences that follow language-like rules. This groundbreaking study provides long-sought evidence that the ability to perceive dependencies between non-adjacent acoustic signals is innate.
Are brain delays a computational disadvantage?
Biological components are less reliable than electrical ones, and rather than instantaneously receive the incoming signals, the signals arrive with a variety of delays.
Two-stage computer algorithm will detect epilepsy with high precision
Scientists elaborated algorithm that much better detects epilepsy on EEG recordings, than other automated methods. To achieve this, authors combined two approaches to analysis of signals of brain activity – classifier, that doesn’t require education, and trainable neural network. The project will enable to automate analysis of EEG and so simplify the process of detecting of epilepsy. Results of the research, supported by the grant of Presidential program of Russian Scientific Foundation, are published in the magazine IEEE Access.

Brain Activity Helps Explain Response to Alcohol and How People Recognize Emotions Before Becoming Intoxicated
People who need to drink relatively high amounts of alcohol before feeling its effects, a genetically influenced risk factor for future heavy drinking and alcohol problems, may have differences in brain connectivity that impair their ability to interpret facial expressions and recognize their own intoxication, a new study suggests. The paper, in Alcoholism: Clinical & Experimental Research, is believed to be the first to demonstrate differences in brain connectivity between people with low and high responses to alcohol. Varying levels of responses to alcohol — for example, how many drinks a person consumes before feeling intoxicated — are known to be related to neurobiological processing. Low responders, who drink more alcohol before feeling affected by it, are at greater risk of alcohol use disorder (AUD) than high responders, who feel the effects of fewer drinks. Scientists using functional magnetic resonance imaging (fMRI) are exploring the possibility that low responders are less a
Which Types of Brain Activity Support Conscious Experiences?
Our subjective experience appears to us in a continuous stream of integrated information, and in Chaos, researchers explore the question: Which characteristics should brain activity have to support this type of conscious experiences?
Mapping Cavefish Brains Leads to Neural Origin of Behavioral Evolution
While studied for nearly a century, little is known about how cavefish brains differ. A study is the first to look inside their brains with millimeter resolution to start to understand how the individual neurons and brain regions that drive complex behaviors, including sleep and feeding have evolved. This work has broad implications for the understanding of how brains evolve in many different animal models and is hoped to be widely used by the scientific community.

Time of day differences in neural reward responsiveness in children
The Reward Positivity (∆RewP) event-related potential (ERP), generally quantified as the difference between neural responsiveness to monetary gains (RewP-Gain) and losses (RewP-Loss) is commonly used as an index of neural reward responsiveness. Despite the popularity of this ERP component in…
Study finds empathy can be detected in people whose brains are at rest
UCLA researchers have found that it is possible to assess a person’s ability to feel empathy by studying their brain activity while they are resting rather than while they are engaged in specific tasks.
Researchers Discover Method to Detect Motor-Related Brain Activity
Motor-related brain activity is of great interest to researchers looking for a better way to improve neurorehabilitation, and one factor to consider is the suppression of the specific rhythmic activity of neurons within the sensorimotor cortex of the brain. Studies indicate this feature suffers from variability when using traditional methods to explore it. In the journal Chaos, scientists in Russia are approaching the problem from a different angle to search for a more robust feature of brain activity associated with accomplishing motor tasks.
A method with roots in AI uncovers how humans make choices in groups and social media
