Family size may influence cognitive functioning in later life Posted: 12 May 2022 10:41 AM PDT A new study found that having three or more versus two children has a negative effect on late-life cognition. The results further indicated that this effect was strongest in Northern Europe, where higher fertility decreases financial resources but does not improve social resources in this region. |
Treatment minimizes infants' opioid-related brain abnormalities Posted: 12 May 2022 10:41 AM PDT Researchers have evidence validating the benefits of using medication for opioid use disorder during pregnancy. Brain imaging revealed significant improvements in brain function after treatment. |
Excessive sports training may have negative effects on mood Posted: 12 May 2022 09:19 AM PDT New research on road cyclists sheds light on the importance of monitoring a training session load with the use of heart rate variability measuring tools, to favor assimilation and prevent injuries, and to compare training intensity with mood states the following morning. |
People choose healthier food when with outsiders for fear of being negatively judged Posted: 12 May 2022 09:18 AM PDT People are more likely to choose a healthy food option than an unhealthy food option among people from different social groups because they fear being judged negatively for their choices. |
Video games can help boost children's intelligence Posted: 12 May 2022 09:18 AM PDT Scientists have studied how the screen habits of US children correlates with how their cognitive abilities develop over time. They found that the children who spent an above-average time playing video games increased their intelligence more than the average, while TV watching or social media had neither a positive nor a negative effect. |
Breakthrough tech enables seizure localization in minutes Posted: 12 May 2022 09:18 AM PDT New research introduces a novel network analysis technology that uses minimally invasive resting state electrophysiological recordings to localize seizure onset brain regions and predict seizure outcomes in just 10 minutes. |
Dementia: Combination of 'feelings' and measurements suggest Alzheimer's in the early stage Posted: 12 May 2022 06:27 AM PDT Subjective memory disorders in conjunction with conspicuous levels of beta-amyloid proteins in the cerebrospinal fluid are a strong indication of developing Alzheimer's disease. This is the conclusion of a new study involving about 1,000 older adults. |
Discovery reveals blocking inflammation may lead to chronic pain Posted: 12 May 2022 06:27 AM PDT Using anti-inflammatory drugs and steroids to relieve pain could increase the chances of developing chronic pain. New research puts into question conventional practices used to alleviate pain. Normal recovery from a painful injury involves inflammation and blocking that inflammation with drugs could lead to harder-to-treat pain. |
A brain circuit in the thalamus helps us hold information in mind Posted: 12 May 2022 06:27 AM PDT Researchers have identified a circuit in the anterior thalamus that is necessary for remembering how to navigate a maze. This region could offer a promising target for treatments that could help reverse memory loss in older people, without affecting other parts of the brain. |
Antidepressant use during pregnancy not linked to epilepsy in children Posted: 12 May 2022 06:27 AM PDT A new study suggests that antidepressant use by mothers during the first trimester of pregnancy does not increase the chances of epilepsy and seizures in babies. |
Study finds increased risk of dementia after hospitalization for major TBI Posted: 12 May 2022 06:27 AM PDT People who have been hospitalized for a major traumatic brain injury (TBI) may have a higher risk of developing dementia when compared to people who do not have a TBI, according to a new study. Major TBI was defined as having bleeding in the brain and a hospital stay of three or more days. Researchers did not find an increased risk for people who had minor TBI, which was defined as a concussion with no more than a one-day hospital stay. |
Genetic study confirms sarin nerve gas as cause of Gulf War illness Posted: 12 May 2022 06:26 AM PDT For three decades, scientists have debated the underlying cause of Gulf War illness (GWI), a collection of unexplained and chronic symptoms affecting veterans of the Persian Gulf War. Now researchers have solved the mystery, showing through a detailed genetic study that the nerve gas sarin was largely responsible for the syndrome. |
Slow walking may be to blame for perceived congestion in pedestrian areas Posted: 12 May 2022 06:26 AM PDT When designing public spaces or other places where foot traffic is considered, planners and architects need to know how people perceive the spaces in question. It is commonly believed that a space will feel more congested if the crowd density is higher. However, new research suggests that walking speed of individuals actually plays a greater role than crowd density in how someone feels about a busy space. Also, age and gender seem to affect someone's perception of how congested an enclosed space feels to them. |
When unconscious, the brain is anything but 'silent' Posted: 12 May 2022 06:26 AM PDT The cerebral cortex is thought to be the seat of conscious processing in the brain. Rather than being inactivated, specific cells in the cortex show higher spontaneous activity during general anesthesia than when awake, and this activity is synchronized across those cortical cells. Improving our understanding of the neuronal mechanisms of general anesthesia could lead to better anesthetic drugs and improved surgical outcomes. |
Designer neurons offer new hope for treatment of Parkinson's disease Posted: 11 May 2022 09:36 AM PDT Scientists describe a process for converting non-neuronal cells into functioning neurons able to take up residence in the brain, send out their fibrous branches across neural tissue, form synapses, dispense dopamine and restore capacities undermined by Parkinson's destruction of dopaminergic cells. |
Life after death for the human eye: Vision scientists revive light-sensing cells in organ donor eyes Posted: 11 May 2022 09:35 AM PDT Scientists have revived light-sensing neuron cells in organ donor eyes and restored communication between them as part of a series of discoveries that stand to transform brain and vision research. Billions of neurons in the central nervous system transmit sensory information as electrical signals; in the eye, specialized neurons known as photoreceptors sense light. |
Key protein identified for brain stem cell longevity Posted: 11 May 2022 09:35 AM PDT A receptor that was first identified as necessary for insulin action, that also is located on the neural stem cells found deep in the brains of mice, is pivotal for brain stem cell longevity, according to a new study, a finding that has important implications for brain health and future therapies for brain disorders. |
Clues about concussions from the gut Posted: 10 May 2022 12:15 PM PDT Scientists suggest telltale signs of concussions might be found in the gut. By taking blood, stool and saliva samples from 33 football players, the researchers were able to examine the diagnostic potential of the gut's microbiome. They say their findings demonstrate that a simple, objective diagnostic test could be developed to track the impact of concussions and signal when it's safe to return to action. |
Posted: 10 May 2022 12:14 PM PDT It is well documented that lying during interviews takes up more cognitive energy than telling the truth. A new study found that investigators who used this finding to their advantage by asking a suspect to carry out an additional, secondary, task while being questioned were more likely to expose lie tellers. The extra brain power needed to concentrate on a secondary task (other than lying) was particularly challenging for lie tellers. |
