How Our Body "Hears" VibrationsNews
Researchers have observed what happens in the brains of mice whose forepaws perceive vibrations. They discovered that neurons in the somatosensory cortex are activated in a manner similar to those in the sound-reactive auditory cortex. These results suggest that feeling a phone vibrate or hearing it ring is ultimately based on the same brain codes.READ MORE
Hunting the Brain Circuits Behind Alcohol CravingsNews
Scientists at Scripps Research have found that they can reverse the desire to drink in alcohol-dependent rats—with the flip of a switch. The researchers were able to use lasers to temporarily inactivate a specific neuronal population, reversing alcohol-seeking behavior and even reducing the physical symptoms of withdrawal.
BRAIN Scientists Make Strides in Mapping the Mouse CortexNews
Researchers have outlined a way to classify neurons based not only on how they look, but on with which other neurons they are capable of communicating.READ MORE
Researchers at UNIGE have successfully demonstrated that electroencephalography can be used to accurately study activity in the deep areas of the brain. The way is now open to understanding how these regions interact with other parts of the brain for developing appropriate treatments following dysfunction.
A single misbehaving protein – called TDP-43 – is behind 97 percent of amyotrophic lateral sclerosis (ALS) cases and 45 percent of frontotemporal dementia diagnoses. It also is found in 80 percent of chronic traumatic encephalopathy and 60 percent of Alzheimer’s disease cases. Now, researchers have found a way to trap TDP-43 so it doesn’t form toxic clumps that can cause neurodegeneration.READ MORE
The microscopic roundworm Caenorhabditis elegans, or C. elegans, is known to spend up to 20 minutes seeking out snacks in its immediate surroundings before endeavoring to look elsewhere. Now, Rockefeller scientists have identified circuits in the C. elegans brain that underlie this behavior, showing that this response can be triggered by either smell- or touch-related cues.
A new study shows the African grey can perform some cognitive tasks at levels beyond that of 5-year-old humans. The results not only suggest that humans aren’t the only species capable of making complex inferences, but also point to flaws in a widely used test of animal intelligence.READ MORE
Brain cells recorded as among the least electrically active during a specific task may be the most important for doing it right. Results of new experiments in rodents, led by neuroscientists at NYU School of Medicine, challenge the assumption in brain research that the most active brain cells, or neurons, involved in any complex activity are also the most important in controlling that behavior.READ MORE
When it comes to reading a person’s state of mind, visual context — as in background and action — is just as important as facial expressions and body language, according to a new study from UC Berkeley.
The pioneering clinical trials program delivered an experimental treatment directly to the brain. The trial results offer hope that it may be possible to restore the cells damaged in Parkinson’s.READ MORE
Many scientists think that the cause of dyslexia is a dysfunctional processing of auditory speech. However, the reasons for these alterations in speech processing remain unknown. A long-standing assumption is that developmental dyslexia is caused by dysfunction of structures in the cerebral cortex. New research shows that people with dyslexia have a weakly developed structure that is not located in the cerebral cortex, but at a subcortical processing stage.READ MORE
People who believe in conspiracy theories – such as the theory that Princess Diana was murdered by the British establishment - are more likely to accept or engage in everyday criminal activity. That’s the main finding from new research by psychologists at the universities of Kent and Staffordshire into the wider impact that conspiracy beliefs can have on behaviour.
