Although psychiatric disorders can be linked to particular genes, the brain regions and mechanisms underlying particular disorders are not well-understood. Mutations or deletions of the SHANK3 gene are strongly associated with autism spectrum disorder (ASD) and a related rare disorder called Phelan-McDermid syndrome. Mice with SHANK3 mutations also display some of the traits associated with […]
Less than one hour of brain training with neurofeedback leads to a strengthening of neural connections and communication among brain areas. This is the main finding of a new study conducted at D’Or Institute for Research and Education (IDOR), published today in Neuroimage. According to the authors, the study may pave the way for the […]
Sleep disruptions are associated with many brain disorders, including anxiety, dementias, and traumatic brain injury. While these disruptions are sometimes viewed as a side effect of brain disorders, new findings presented today suggest that aberrant sleep-wake cycles can also drive brain pathology. The studies were presented at Neuroscience 2018, the annual meeting of the Society […]
Think of the brain as a complex transportation hub, a place where neural traffic heads off in any number of directions to make connections while processing something as simple as a mother’s smile. Now consider the same center in a child with an autism spectrum disorder (ASD). At a time different parts of the brain […]
The way we breathe may affect how well our memories are consolidated (i.e. reinforced and stabilised). If we breathe through the nose rather than the mouth after trying to learn a set of smells, we remember them better, researchers at Karolinska Institutet in Sweden report in The Journal of Neuroscience. Research into how breathing affects […]
Some patterns of electrical activity generated by the brain during sleep are inherited, according to a study of teenage twins published in JNeurosci. Pinpointing the relative contributions of biology and experience to sleep neurophysiology could inform therapies for numerous psychiatric disorders in which alterations in brain activity during sleep can be detected. Leila Tarokh and […]
In both ADHD and emotional instability disorders (e.g. borderline and antisocial personality disorder as well as conduct disorder in children), the brain exhibits similar changes in overlapping areas, meaning that the two types of conditions should be seen as related and attention should be paid to both during diagnosis. This according to researchers at Karolinska […]
Happy older people live longer, according to researchers at Duke-NUS Medical School in Singapore. In a study published today in Age and Ageing, the scientific journal of the British Geriatrics Society, the authors found that an increase in happiness is directly proportional with a reduction in mortality. The study utilised data for 4,478 participants of […]
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 […]
