| Robotic 'Third Thumb' use can alter brain representation of the hand Posted: 20 May 2021 01:03 PM PDT Using a robotic 'Third Thumb' can impact how the hand is represented in the brain, finds a new study. |
| Brain stimulation evoking sense of touch improves control of robotic arm Posted: 20 May 2021 11:53 AM PDT The brain-computer interface user was able to transfer objects with a robotic arm at twice the speed of doing it without the tactile feedback. |
| Independent of IQ, 'decision acuity' predicts broad range of decision-making abilities Posted: 20 May 2021 10:39 AM PDT A common factor called 'decision acuity' underpins diverse decision-making abilities in adolescents and young adults, suggests a new study. A large set of behavioral and neuroimaging data revealed that decision acuity is stable over time, distinct from IQ, and reduced in individuals with low general social functioning. |
| Epigenetic mechanism can explain how chemicals in plastic may cause lower IQ levels Posted: 20 May 2021 10:37 AM PDT The chemical bisphenol F (found in plastics) can induce changes in a gene that is vital for neurological development. The mechanism could explain why exposure to this chemical during the fetal stage may be connected with a lower IQ at seven years of age -- an association previously seen by the same research group. |
| New insight into protein production in brain could help tackle dementia Posted: 19 May 2021 09:07 AM PDT Scientists have revealed a layer of genetic material involved in controlling the production of tau; a protein which plays a critical role in serious degenerative conditions, such as Parkinson's and Alzheimer's disease. |
| Single fingerprint at a crime scene detects class A drug usage Posted: 19 May 2021 09:07 AM PDT The latest findings show that with clever science, a single fingerprint left at a crime scene could be used to determine whether someone has touched or ingested class A drugs. |
| Alzheimer protein APP regulates learning and social behavior in the healthy brain Posted: 19 May 2021 09:07 AM PDT The APP protein is known for its role in Alzheimer's disease, but its contribution to healthy brain function remains largely unexplored. Using a mouse model, a research team gained new insights on the physiological functions of the APP protein family. The absence of APP during brain development was shown to result in malformations of brain regions implicated in learning and memory, severely impairing learning in the mice and causing autistic-like behavior. |
| Researchers identify potential approach to controlling epileptic seizures Posted: 19 May 2021 05:05 AM PDT Researchers have identified a potential new approach to better controlling epileptic seizures. |
| An illuminating possibility for stroke treatment: Nano-photosynthesis Posted: 19 May 2021 05:05 AM PDT Blocked blood vessels in the brains of stroke patients prevent oxygen-rich blood from getting to cells, causing severe damage. Plants and some microbes produce oxygen through photosynthesis. What if there was a way to make photosynthesis happen in the brains of patients? Now, researchers have done just that in cells and in mice, using blue-green algae and special nanoparticles, in a proof-of-concept demonstration. |
| Potential causality between blood clot factors and migraine with aura Posted: 18 May 2021 10:08 AM PDT Researchers used a technique in genetic analysis termed Mendelian randomization to examine 12 coagulation measures, uncovering four that are associated with migraine susceptibility. |
| How a virtual program may help kids get ready for kindergarten Posted: 18 May 2021 08:49 AM PDT With pandemic lockdowns still in place last summer, The Ohio State University couldn't host its in-person Summer Success Program to help preschoolers from low-income families prepare for kindergarten. Staff and teachers quickly pivoted to a fully virtual program, but they were worried: Could this really work with 4- and 5-year-olds who had no previous experience with preschool? A new study suggested it did. |
| Mutation linked to autism impairs oxytocin-mediated social behavior in mice Posted: 18 May 2021 08:41 AM PDT Mutations associated with autism can inhibit the release of the bonding hormone oxytocin and cause abnormal social behavior in mice, researchers report. |
| Insulin is necessary for repairing olfactory neurons Posted: 17 May 2021 04:46 PM PDT Insulin plays a critical role in the maturation, after injury, of immature olfactory sensory neurons. Applying insulin into the nasal passage could be developed as a therapy for injury caused by a host of issues. |
| Alcohol problems severely undertreated Posted: 17 May 2021 11:47 AM PDT Researchers have found that although the vast majority of people with alcohol use disorder see their doctors regularly for a range of issues, fewer than one in 10 ever get treatment to help curb their drinking. |
| Warnings on the dangers of screen time are ill founded, review finds Posted: 17 May 2021 09:49 AM PDT A new review finds that research requiring participants to estimate their own digital screen time cannot provide reliable information on mental health impact. |
