Neanderthal DNA may influence modern depression risk A new study says a person’s risk of becoming depressed or hooked on smoking may be influenced by DNA inherited from Neanderthals.
A cluttered kitchen can nudge us to overeat People with an orderly kitchen are less likely to snack than others with a messy kitchen.
Low B12 seen in aging, autism and schizophrenia The brains of the elderly and younger people with autism and schizophrenia may share a common link: Both have low levels of vitamin B12, researchers say.
Why Are People With ADHD Always Late? Chronic lateness can be one of the most annoying symptoms of ADHD, both for people with ADHD and those who have to put up with us! But why is ADHD … ...
Study suggests sugar can be as damaging to the brain as early life stress We all know that cola and lemonade aren’t great for our waistline or our dental health, but our new study on rats has shed light on just how much damage sugary drinks can also do to our brain. The changes we observed to the region of the brain that controls emotional behaviour and cognitive function [...]
Languages are in competition with one another in bilingual brains Bilinguals use and learn language in ways that change their minds and brains, which has consequences — many positive, according to Judith F. Kroll, a Penn State cognitive scientist. “Recent studies reveal the remarkable ways in which bilingualism changes the brain networks that enable skilled cognition, support fluent language performance and facilitate new learning,” said [...]
Study on self-compassion finds virtual reality therapy could help people with depression An immersive virtual reality therapy could help people with depression to be less critical and more compassionate towards themselves, reducing depressive symptoms, finds a new study from UCL (University College London) and ICREA-University of Barcelona. The therapy, previously tested by healthy volunteers, was used by 15 depression patients aged 23-61. Nine reported reduced depressive symptoms [...]
Speech disorder called apraxia can progress to neurodegenerative disease It may start with a simple word you can’t pronounce. Your tongue and lips stumble, and gibberish comes out. Misspeaking might draw a chuckle from family and friends. But, then, it keeps happening. Progressively, more and more speech is lost. Some patients eventually become mute from primary progressive apraxia of speech, a disorder related to [...]
Does happiness come from within or from external factors? “Happiness comes from within.” This is an idea that has been around for quite some time, bubbling up from ancient Stoic and Buddhist philosophers but being reinforced today by modern new age gurus and the modern science of positive psychology. We have the power to change our mental and emotional responses to the world around [...]
Is schizophrenia written in our genes? Scientists have identified hundreds of regions of the human genome that are linked with schizophrenia. These findings are exciting because they provide clues to the biological basis of this devastating disorder – clues that may ultimately help us to develop better treatments. However, attempts to understand how genes contribute to the symptoms that patients experience [...]
Men spend more money after being romantically rejected — women do the opposite Money might not buy you love, but according to some studies in psychology and consumer behaviour, how you spend it could reveal a thing or two about your romantic intentions. These studies demonstrate that just thinking about meeting a new partner can actually impact our shopping decisions in surprising ways – affecting men and women [...]
When it comes to dating, take Nietzsche’s advice and have the big picture in mind Online dating sites and apps are transforming relationships. More than 10 percent of American adults – and almost 40 percent of people who identify as “single and looking” – are using online dating websites and apps. But what might someone from the 19th century think about this unique fusion of technology and romance? In the [...]
Noradrenergic neurons may determine a person’s vulnerability to depression The team of Bruno Giros, a researcher at the Douglas Mental Health University Institute and professor of psychiatry at McGill University, reports the first-ever connection between noradrenergic neurons and vulnerability to depression. Published in the journal Nature Neuroscience, this breakthrough paves the way for new depression treatments that target the adrenergic system. Stressful life events–job [...]
Jawless fish brains more similar to ours than previously thought Researchers at the RIKEN Evolutionary Morphology laboratory and other institutions in Japan have shown that complex divisions in the vertebrate brain first appeared before the evolution of jaws, more than 500 million years ago. Published in Nature, the study shows that two elements of brain genoarchitecture thought to be unique to jawed vertebrates are actually [...]
Researchers create ‘mini-brains’ in lab to study neurological diseases Researchers at the Johns Hopkins Bloomberg School of Public Health say they have developed tiny “mini-brains” made up of many of the neurons and cells of the human brain — and even some of its functionality — and which can be replicated on a large scale. The researchers say that the creation of these “mini-brains,” [...]
Researchers identify ‘neurostatin’ that may reduce the risk of Alzheimer’s disease Researchers have identified a drug that targets the first step in the toxic chain reaction leading to the death of brain cells, suggesting that treatments could be developed to protect against Alzheimer’s disease, in a similar way to how statins are able to reduce the risk of developing heart disease. The drug, which is an [...]
Brain prepares for the future by replaying rewarding events in memory Why do we remember some events, places and things, but not others? Our brains prioritize rewarding memories over others, and reinforce them by replaying them when we are at rest, according to new research from the University of California, Davis, Center for Neuroscience, published Feb. 11 in the journal Neuron. “Rewards help you remember things, [...]
Displays of ethical conduct linked to abusive behavior in bosses Is your boss ethical? Does he or she do what’s right, as opposed to what’s profitable? If so, they may turn downright abusive the next day. New research on leader behavior by Russell Johnson, associate professor of management at Michigan State University, suggests ethical conduct leads to mental exhaustion and the “moral licensing” to lash [...]
A Long-Term Study of Changing High School Start Time One study shows that benefits of later school start time are lost after a while.
