Phys.org / Repeat thieves without kleptomania struggle to adapt to rewards in decision-making test
Theft is almost universally considered an exploitative behavior. The conventional view underlying judicial systems is that the act of taking resources from others without offering compensation stems from moral and personal ...
Medical Xpress / Timely, far-reaching theta waves help organize cognition, study shows
Cognition has to be organized somehow. A new study by researchers in The Picower Institute for Learning and Memory at MIT provides several lines of evidence that the needed organization is implemented across the brain's frontal ...
Medical Xpress / Your brain may map emotional concepts onto a hexagonal grid, new study suggests
Everyday life throws a whole range of emotional experiences our way, from exciting and relaxing moments to tense or gloomy encounters. Each experience is shaped by what's present around us in the moment, the sensations our ...
Medical Xpress / A possible chemical explanation for why we give up on tough tasks
When we engage our brains in a mentally taxing task, we eventually reach a point where we hit a wall or run on empty. Even when the rewards of finishing are obvious, we often find ourselves simply stopping. Exactly why this ...
Medical Xpress / In parallel mouse studies, researchers fail to replicate many reported effects of psilocybin
Experimental trials of psychedelic drugs in both humans and animals have produced conflicting results, creating doubts about whether hallucinogens have a therapeutic role in treating neurologic or behavioral disorders such ...
Medical Xpress / Brain scans challenge link between prefrontal activity and ability to regulate emotions
A person's capacity to regulate their emotions apparently cannot be determined by the activity of the prefrontal brain regions typically associated with this process. This is shown by an international fMRI analysis conducted ...

Medical Xpress / Small deep brain structure may play major role in sustaining working memory, mouse experiments suggest
Reading a sentence, following a conversation, solving a problem or deciding what to do next: all of these rely on working memory. It allows the brain to hold information in mind for a few seconds, even after the stimulus ...
Medical Xpress / Detailed brain map reveals how the insula shapes bodily sensations and processes pain
Tucked deep within the human brain's lateral fissure, beneath layers of the cerebral cortex, lies the insula. It is the hub that controls sensations ranging from pain and physical touch to hunger and emotions. Yet, it remains ...
Medical Xpress / Wireless neural chip tracks brain changes in real time after Alzheimer's drug administration
A joint research team led by KAIST has used a small, implantable neural chip to wirelessly monitor real-time changes in a neurotransmitter involved in memory and learning after an Alzheimer's drug has been administered. In ...
Phys.org / Crows make decisions twice as fast as humans and monkeys
University of Tübingen researchers have shown that crows, when confronted with a visual choice, make a decision twice as fast as humans and monkeys. In the experiment, two carrion crows took just 235 milliseconds on average ...
