How Sleep Helps to Process Emotions
(Neuroscience News) Researchers at the Department of Neurology of the University of Bern and University Hospital Bern identified how the brain triages emotions during dream sleep to consolidate the storage of positive emotions while dampening the consolidation of negative ones.
Increased Mutations in Children Can Be Traced Back to Mistakes in Father’s Sperm
(Neuroscience News) Some rare cases of higher genetic mutation rates in children, known as hypermutation, could be linked to the father receiving certain chemotherapy treatments, new research has found.
Common Fungicide Detected in Pregnant Women and Children
(Neuroscience News) For the first time, UNC-Chapel Hill researchers have measured the concentration of a biomarker of the commonly used fungicide azoxystrobin (AZ) in the urine of pregnant women and children ranging from 40–84 months of age. They also documented maternal transfer of AZ to mouse embryos and weaning-age mice.
Children With History of Maltreatment Could Undergo an Early Maturation of the Immune System
(Neuroscience News) Acute psychosocial stress states stimulate the secretion of an antibody type protein that is decisive in the first immune defense against infection, but only after puberty. However, children with a history of maltreatment present a similar response to that of adolescents, which suggests there is an early maturation of the immune system in these cases.
Feeling Sensations, Including Ones Connected to Sadness, May Be Key to Depression Recovery
(Neuroscience News) The physical sensations that accompany sadness can feel as undesirable as they are intense—a constriction of the chest, watery eyes and a raw throat, to name a few.
How Cannabis Affects Our Cognition and Psychology
(Neuroscience News) Cannabis has been used by humans for thousands of years and is one of the most popular drugs today. With effects such as feelings of joy and relaxation, it is also legal to prescribe or take in several countries.
Recalled Experiences Surrounding Death: More Than Hallucinations?
(Neuroscience News) Scientific advances in the 20th and 21st centuries have led to a major evolution in the understanding of death. At the same time, for decades, people who have survived an encounter with death have recalled unexplained lucid episodes involving heightened consciousness and awareness. These have been reported using the popular—yet scientifically ill-defined—term “near-death experiences”.
Caffeine Could Be a Valid Option for Treating Some ADHD Symptoms
(Neuroscience News) Attention Deficit Hyperactivity Disorder, or ADHD, is a psychiatric pathology for which diagnosis has increased exponentially over the last 20 years. In fact, current estimates suggest that this disorder affects between 2% and 5% of children in Spain, an average of one or two children per classroom, and up to 4% of the adult population.
Largest Ever Psychedelics Study Maps Changes of Conscious Awareness to Neurotransmitter Systems
(Neuroscience News) Psychedelics are now a rapidly growing area of neuroscience and clinical research, one that may produce much-needed new therapies for disorders such as depression and schizophrenia. Yet there is still a lot to know about how these drug agents alter states of consciousness.
Live Fast, Die Young? Or Live Cold, Die Old?
(Neuroscience News) Researchers from the Shenzhen Institute of Advanced Technology (SIAT) of the Chinese Academy of Sciences, along with collaborators from Wenzhou University and the University of Aberdeen, have found that body temperature exerts a greater effect on lifespan than metabolic rate.
Daily Photo Sharing Might Mean Double Depression Risk
(Neuroscience News) The rate of reported depressive symptoms that are likely to require treatment has more than doubled by the third wave of the COVID-19 pandemic among those who most often share pictures or videos of themselves on social media, according to a recent study published in The International Journal of Interdisciplinary Social and Community Studies.
How Early Life Experiences May Affect Brain Wiring
(Neuroscience News) A new study of brain development in mice shortly after birth may provide insights into how early life events can affect wiring patterns in the brain that manifest as disease later in life – specifically such disorders as schizophrenia, epilepsy, and autism.
Neurons Are Fickle. Electric Fields Are More Reliable for Information
(Neuroscience News) A new study suggests that electric fields may represent information held in working memory, allowing the brain to overcome “representational drift,” or the inconsistent participation of individual neurons.
Air Pollution Can Harm Pregnancy by Affecting Gene Expression in the Placenta
(Neuroscience News) Polluted air contributed to the deaths of more than 6.6 million people worldwide in 2019. It accounts for around 20 percent of newborn deaths globally, mostly due to preterm birth and low birth weight. Because of this, it is crucial that researchers and policymakers working to improve public health understand how different aspects of various types of air pollution and their associated biological responses affect fetal development.
