| The immune link between a leaky blood-brain barrier and schizophrenia Posted: 20 Apr 2021 03:31 PM PDT Research points to the involvement of the immune system the brain as a contributor to mental disorders such as schizophrenia. |
| Astronauts' mental health risks tested in the Antarctic Posted: 20 Apr 2021 09:15 AM PDT Astronauts who spend prolonged time alone in space face mental health stressors like loneliness, isolation and more. A psychologist developed the Mental Health Checklist, a self-reporting instrument for detecting mental health changes in isolated, confined, extreme environments. She's reporting results that show significant declines in positive emotions. |
| A gene finding links severe canine juvenile epilepsy to mitochondrial dysfunction Posted: 20 Apr 2021 09:15 AM PDT Researchers found a cause for severe epilepsy resulting in death in Parson Russell Terrier puppies at a few months of age. A change in the PITRM1 gene can lead to a dysfunction of mitochondria, the cellular energy pumps. Concurrently, amyloid-beta accumulation and widespread neurodegeneration associated with Alzheimer's disease were identified in the puppies' brains. Changes to the PITRM1 gene in humans also cause a severe but slowly progressing brain disease. |
| Is social media use a potentially addictive behavior? Maybe not Posted: 20 Apr 2021 09:14 AM PDT Frequent use of social media may not amount to the same as addiction, according to new research. |
| Role of physical, mental health in cognitive impairment Posted: 20 Apr 2021 09:14 AM PDT A recent study suggests that preserving physical and mental health helps older adults experiencing cognitive impairment stave off declines in cognitive engagement. |
| Our attention is captured by eye-glance Posted: 20 Apr 2021 06:29 AM PDT Researchers looked at the way we process human gaze, focusing on the estimation of the temporal duration of social interactions. They discovered that when we make eye contact with another person, our attention is solicited, causing a distortion in our temporal perception: time seems shorter than it really is. These results will make it possible to develop a diagnostic tool to evaluate the mechanisms at work in people who are sensitive to social gaze. |
| Individualized training is key for autistic adolescents learning to drive Posted: 20 Apr 2021 06:28 AM PDT A new study identified clear strengths and a series of specific challenges autistic adolescents experience while learning to drive. |
| Disrupted sleep is linked to increased risk of early death, particularly in women Posted: 19 Apr 2021 04:52 PM PDT For the first time, a study has shown a clear link between the frequency and duration of unconscious wakefulness during night-time sleep and an increased risk of dying from diseases of the heart and blood vessels, and death from any cause, particularly in women. |
| Supplement treats schizophrenia in mice, restores healthy 'dance' and structure of neurons Posted: 19 Apr 2021 08:01 AM PDT A simple dietary supplement reduces behavioral symptoms in mice with a genetic mutation that causes schizophrenia. After additional experiments, including visualizing the fluorescently stained dancing edge of immature brain cells, researchers concluded that the supplement likely protects proteins that build neurons' cellular skeletons. |
| Mirror, mirror: Viewing your own face, even subconsciously, is rewarding Posted: 19 Apr 2021 06:51 AM PDT Researchers have found that the subliminal presentation of images of one's own face activates a central component of the dopamine reward pathway, thus illuminating the mechanisms behind our powerful ability to automatically prioritize processing of our own face. These findings have important implications for understanding the neural processes involved in automatic self-advantage in face processing, as well as discriminating the processes involved in supraliminal (conscious) and subliminal (subconscious) facial perceptions. |
