| Brain circuit for spirituality? Posted: 01 Jul 2021 04:52 PM PDT Using datasets from neurosurgical patients and those with brain lesions, researchers mapped lesion locations associated with spiritual and religious belief to a specific human brain circuit. |
| Scientists discover a new class of memory cells for remembering faces Posted: 01 Jul 2021 11:09 AM PDT Our brains have sensory cells, which process the faces that we see, and memory cells dedicated to storing data from person encounters. But until now, a hybrid neuron capable of linking vision to memory -- and explaining how we recall familiar faces -- remained elusive. |
| The key role of astrocytes in cognitive development Posted: 01 Jul 2021 11:09 AM PDT Researchers have now uncovered their crucial role in closing the period of brain plasticity that follows birth, finding them to be key to the development of sensory and cognitive faculties. Over the longer term, these findings will make it possible to envisage new strategies for reintroducing brain plasticity in adults, thereby promoting rehabilitation following brain lesions or neurodevelopmental disorders. |
| Fibromyalgia likely the result of autoimmune problems Posted: 01 Jul 2021 09:07 AM PDT New research has shown that many of the symptoms in fibromyalgia syndrome (FMS) are caused by antibodies that increase the activity of pain-sensing nerves throughout the body. The results show that fibromyalgia is a disease of the immune system, rather than the currently held view that it originates in the brain. |
| How children integrate information Posted: 01 Jul 2021 08:27 AM PDT Researchers use a computer model to explain how children integrate information during word learning. |
| Discovery of nano-sized molecules that might inhibit Alzheimer's and Parkinson's diseases Posted: 01 Jul 2021 08:26 AM PDT Nanosized molecules of a particular chemical element can inhibit the formation of plaque in the brain tissues, according to researchers. The discovery provides renewed hope for novel treatments of, for instance, Alzheimer's and Parkinson's disease in the long run. |
| Scientists find genetic cause, underlying mechanisms of new neurodevelopmental syndrome Posted: 01 Jul 2021 08:26 AM PDT Scientists have demonstrated that variants in the SPTBN1 gene can alter neuronal architecture, dramatically affecting their function and leading to a rare, newly defined neurodevelopmental syndrome in children. |
| The sense of smell in older adults declines when it comes to meat, but not vanilla, researchers find Posted: 01 Jul 2021 08:26 AM PDT Contrary to what science once suggested, older people with a declining sense of smell do not have comprehensively dampened olfactory ability for odors in general -- it simply depends upon the type of odor. Researchers reached this conclusion after examining a large group of older Danes' and their intensity perception of common food odors. |
| Consuming a diet with more fish fats, less vegetable oils can reduce migraine headaches, study finds Posted: 30 Jun 2021 06:30 PM PDT A diet higher in fatty fish helped frequent migraine sufferers reduce their monthly number of headaches and intensity of pain compared to participants on a diet higher in vegetable-based fats and oils, according to a new study. |
| Report sounds alarm on efficacy, safety, ethics of embryo selection with polygenic scores Posted: 30 Jun 2021 02:36 PM PDT A new report raises serious questions about the benefits, risks and ethics of a new service -- which the authors call 'embryo selection based on polygenic scores,' or ESPS -- that allows in vitro fertilization patients to select embryos with the goal of choosing healthier and even smarter children. |
| High physical activity levels may counter serious health harms of poor sleep Posted: 29 Jun 2021 04:17 PM PDT Physical activity levels at or above the weekly recommended amounts may counter the serious health harms associated with poor sleep quality, suggests a large long term study. |
