People’s motivation to cling to desirable notions about future outlooks results from interactions between prefrontal cortex regions, according to a human neuroimaging study published in JNeurosci. Bojana Kuzmanovic and colleagues uncovered circuits in the brain that support belief updating by asking participants to estimate their own and a peer’s likelihood of experiencing an adverse life […]
There is new hope for the treatment of Alzheimer’s and other neurological diseases following a ground-breaking discovery made by an Australian-Chinese research collaboration. Researchers from the University of South Australia and the Third Military Medical University in China have discovered a signal pathway within cells, and also invented a potential drug that could stop degeneration […]
Practice is necessary to improve motor skills. Even if one performs poorly at first, one’s athletic performance improves through repeated exercise due to the reduction of motor errors as the brain learns. However, it’s important to remember that there are two types of errors: motor errors caused by poor motor control and target errors caused […]
A new, highly accurate MRI technique can monitor iron levels in the brains of multiple sclerosis (MS) patients and help identify those at a higher risk for developing physical disability, according to a study published in the journal Radiology. MS is a disease that attacks three critical components of the central nervous system: the neurons […]
