A bird listening to birdsong may experience some of the same emotions as a human listening to music, suggests a new study on white-throated sparrows, published in Frontiers of Evolutionary Neuroscience.

Scientists at University College Cork (UCC) have come up with an innovative strategy to deliver a therapy into the brain to treat the neurogenerative disease, Huntington’s disease (HD). The strategy, which involves using modified sugars to carry gene therapies into the brain, is being hailed as an exciting development which could be applied to many brain disorders, especially those with a genetic basis.

Researchers have used brain imaging technology to show that young people with a known genetic risk of bipolar but no clinical signs of the condition have clear and quantifiable differences in brain activity when compared to controls.

Scientists have identified a previously unknown group of nerve cells in the brain. The nerve cells regulate cardiovascular functions such as heart rhythm and blood pressure. It is hoped that the discovery, which is published in the Journal of Clinical Investigation, will be significant in the long term in the treatment of cardiovascular diseases in humans.

Scientists say they have found a way to distinguish between different types of dementia without the need for invasive tests, like a lumbar puncture.

Scientists at the University of Western Ontario have discovered that perhaps IQ is not the best measure of cognitive performance. Instead, they found that verbal language, short-term memory, and logical reasoning were the most important predictors of cognitive performance.

Weekly Neuroscience Update

this way, that wayWellcome Trust researchers have discovered how the brain assesses confidence in its decisions. The findings explain why some people have better insight into their choices than others.

Meanwhile, a study conducted by researchers at the University of Granada Group of Neuropsychology and Clinical Psychoneuroimmunology has demonstrated that cortisol levels in saliva are associated with a person’s ability to make good decisions in stressful situations.

Your brain has at least four different senses of location – and perhaps as many as 10. And each is different, according to new research from the Kavli Institute for Systems Neuroscience.

A month of daily transcranial magnetic stimulation targeting the supplemental motor area (SMA) results in lasting improvements in symptoms of Tourette syndrome, show study findings.

Researchers have used brain imaging technology to show that young people with a known genetic risk of bipolar but no clinical signs of the condition have clear and quantifiable differences in brain activity when compared to controls.

Researchers have found the first proof that a chemical in the brain called glutamate is linked to suicidal behavior, offering new hope for efforts to prevent people from taking their own lives.

Neurobiologists at the Research Institute of Molecular Pathology (IMP) in Vienna investigated how the brain is able to group external stimuli into stable categories. They found the answer in the discrete dynamics of neuronal circuits. The journal Neuron publishes the results in its current issue.

Weekly Round Up

A part of the human brain that’s involved in emotion gets particularly excited at the sight of animals, a new study has shown. The brain structure in question is the amygdala: that almond-shaped, sub-cortical bundle of nuclei that used to be considered the brain’s fear centre, but which is now known to be involved in many aspects of emotional learning.

Studies have shown that ­meditating regularly can help relieve chronic pain, but the neural mechanisms ­underlying the relief were unclear. Now, ­researchers from MIT, Harvard, and Massachusetts General ­Hospital have found a possible explanation.

Men and women differ in the way they anticipate an unpleasant emotional experience, which influences the effectiveness with which that experience is committed to memory according to new research.

New research has contradicted a 40-year-old theory of how the brain controls impulsive behavior

Head trauma may increase the risk of developing schizophrenia, a new study says. The results show people who have suffered from a traumatic brain injury (TBI) are 1.6 times more likely to develop schizophrenia compared with those who have not suffered such an injury.

Researchers from the Royal College of Surgeons in Ireland (RCSI) and Beaumont Hospital have conducted a study which has found striking brain similarities in bipolar disorder and schizophrenia.

The brains of older people are not slower but rather wiser than young brains, which allows older adults to achieve an equivalent level of performance, according to research undertaken at the University Geriatrics Institute of Montreal by Dr. Oury Monchi and Dr. Ruben Martins of the University of Montreal.

A new study testing alcohol’s effects on brain activity finds that alcohol dulls the brain “signal” that warns people when they are making a mistake, ultimately reducing self control.

Researchers in the Netherlands have been able to shed more light on how combat experiences change the brains of soldiers.

And finally, new research from MIT suggests that there are parts of our brain dedicated to language and only language, a finding that marks a major advance in the search for brain regions specialized for sophisticated mental functions.  And this week,new research makes the case that language is not a key part of thinking about numbers, but the key part, overriding other influences like cultural ones.
