Scientists link alcohol-dependence gene to neurotransmitter Scientists at The Scripps Research Institute (TSRI) have solved the mystery of why a specific signaling pathway can be associated with alcohol dependence. This signaling pathway is regulated by a gene, called neurofibromatosis type 1 (Nf1), which TSRI scientists found is linked with excessive drinking in mice. The new research shows Nf1 regulates gamma-aminobutyric acid [...]The post Scientists link alcohol-dependence gene to neurotransmitter appeared first on PsyPost.
Study finds expression of privilege in vaccine refusal Not all students returning to school this month will be up to date on their vaccinations. A new study conducted by Jennifer Reich, a researcher at the University of Colorado Denver, shows that the reasons why children may not be fully vaccinated depends on the class privilege of their mothers. According to the National Network [...]The post Study finds expression of privilege in vaccine refusal appeared first on PsyPost.
Neural engineers discover why learning can be difficult Learning a new skill is easier when it is related to ability that we already possess. For example, a trained pianist might learn a new melody more easily than learning how to hit a tennis serve. Neural engineers from the Center for the Neural Basis of Cognition (CNBC)—a joint program between the University of Pittsburgh [...]The post Neural engineers discover why learning can be difficult appeared first on PsyPost.
Researchers publish first study of brain activation in MS using fNIRS Using functional near infrared spectroscopy (fNIRS), Kessler Foundation researchers have shown differential brain activation patterns between people with multiple sclerosis (MS) and healthy controls. This is the first MS study in which brain activation was studied using fNIRS while participants performed a cognitive task. The article, “Neuroimaging and cognition using functional near infrared spectroscopy (fNIRS) in multiple sclerosis,” [...]The post Researchers publish first study of brain activation in MS using fNIRS appeared first on PsyPost.
Study shows social class makes a difference in how children tackle classroom problems An Indiana University study has found that social class can account for differences in how parents coach their children to manage classroom challenges. Such differences can affect a child’s education by reproducing inequalities in the classroom. “Parents have different beliefs on how to deal with challenges in the classroom,” said Jessica McCrory Calarco, assistant professor [...]The post Study shows social class makes a difference in how children tackle classroom problems appeared first on PsyPost.
New treatment for Multiple Sclerosis being investigated A new treatment under investigation for multiple sclerosis (MS) is safe and tolerable in phase 1 clinical trials, according to a study. Studies with animals showed that the drug may be able to reverse the demyelination of the nerves. Current treatments for MS work to reduce new damage to the brain, but do not repair new or past damage.
Ignore the IQ test: your level of intelligence is not fixed for life By Bryan Roche, National University of Ireland Maynooth We’re getting more stupid. That’s one point made in a recent article in the New Scientist, reporting on a gradual decline in IQs in developed countries such as the UK, Australia and the Netherlands. Such research feeds into a long-held fascination with testing human intelligence. Yet such [...]The post Ignore the IQ test: your level of intelligence is not fixed for life appeared first on PsyPost.
The Secret to Happiness and Compassion: Low Expectations A new MRI study suggests that happier people have lower expectations. I'd argue that compassion too is a product of lowered expectations. So to be as happy and compassionate as possible, lower your expectations of yourself and others. The lower the better. Which is actually an argument that happiness and compassion aren't enough.

Do You Need to Be Liberated From Your Past? Do you feel free to be yourself? Have you ever been told that you overreact to others—or perhaps that you underreact to them? In one way or another, behavioral programs that were adaptive for you in childhood may be continuing, however irrationally, to govern your behavior as an adult. And if this is the case, the present post may offer you some "actionable" insights.
How to Untwist Twisted Thinking Patterns People think that all stress is external. You or someone you know may be walking in these shoes: a single parent with two out-of-control teenagers; facing upheaval at work or job loss; raising children with autism or a disability; or caring for an elderly parent or spouse while raising children...
Relationship Lies: Learn These 4 Dating Myths NOW Ladies No, you won’t “just know” when you meet the right guy. Are you totally baffled as to why you only seem to attract men who are far from ideal for you? Are you tired of ending up with men who aren’t ready for the same type of relationship you want?...
Xenon exposure shown to erase traumatic memories Xenon gas, used in humans for anesthesia and diagnostic imaging, has the potential to be a treatment for post-traumatic stress disorder and other memory-related disorders, researchers report. "We know from previous research that each time an emotional memory is recalled, the brain actually restores it as if it were a new memory. With this knowledge, we decided to see whether we could alter the process by introducing xenon gas immediately after a fear memory was reactivated," explained an author.
Brain networks 'hyper-connected' in young adults who had depression Functional magnetic resonance imaging may help to better predict and understand depression in young adults. The researchers found many regions that are "hyper-connected -- or talking to each other a little too much -- among those who have a history of depression," one researcher said. These hyper-connected brain networks were related to rumination, with individuals thinking about a problem over and over without actively trying to come up with a solution.
Round trip ticket to the science of psychedelics The latest edition of The Psychologist is a special open-access issue on the science and social impact of hallucinogenic drugs. There’s an article by me on culture and hallucinogens that discusses the role of hallucinogenic drugs in diverse cultures and which also covers how cultural expectations shape the hallucinogenic experience – from traditional Kitanemuk society […]
Self Doubt: Challenging Negative Assumptions about Yourself Client: “I believed that my judgment couldn’t be trusted.” Therapist: “That’s right. That was something you have come to accept as ‘fact’. You didn’t question it rationally or objectively when you were a child. And you never went back to check it out as an adult” Client: “I’ve been struggling...
emotional association of memories changed by researchers By manipulating neural circuits in the brain of mice, scientists have altered the emotional associations of specific memories. The research reveals that the connections between the part of the brain that stores contextual information about an experience and the part of the brain that stores the emotional memory of that experience are malleable.
Neuroscientists reverse memories' emotional associations: Brain circuit that links feelings to memories manipulated Most memories have some kind of emotion associated with them: Recalling the week you just spent at the beach probably makes you feel happy, while reflecting on being bullied provokes more negative feelings. A new study from neuroscientists reveals the brain circuit that controls how memories become linked with positive or negative emotions.
Flexing the brain: Why learning tasks can be difficult Learning a new skill is easier when it is related to an ability we already have. For example, a trained pianist can learn a new melody easier than learning how to hit a tennis serve. Scientists have discovered a fundamental constraint in the brain that may explain why this happens.
Impact of cultural diversity in brain injury research The implications for cultural diversity and cultural competence in brain injury research and rehabilitation has been the focus of recent study. Risk for brain injury is higher among minorities, as is the likelihood for poorer outcomes. More research is needed to reduce health disparities and improve outcomes among minorities with brain injury, experts say.
