New insights on how cocaine causes wild firing of dopaminergic neurons in the brain The burst of energy and hyperactivity that comes with a cocaine high is a rather accurate reflection of what’s going on in the brain of its users, finds a study published November 25 in Cell Reports. Through experiments conducted in rats exposed to cocaine, the researchers mapped out the network of circuits that cause wild [...]
How the explosion in prescription painkillers has created more heroin users In the early years of my clinical practice as a psychologist treating heroin users, I commonly saw adolescents and young adults using heroin as their first drug. A typical client was a male in his mid-teens, perhaps a runaway or living in foster care, or someone who had been in and out of juvenile detention, [...]
How cells in the developing ear ‘practice’ hearing Before the fluid of the middle ear drains and sound waves penetrate for the first time, the inner ear cells of newborn rodents practice for their big debut. Researchers at Johns Hopkins report they have figured out the molecular chain of events that enables the cells to make “sounds” on their own, essentially “practicing” their [...]
New research could lead to improved methods of detection for Parkinson’s disease New research by biologists at the University of York could lead to improved methods of detection for early-onset Parkinson’s Disease (PD). Recording the responses of fruit flies (Drosophila melanogaster) to different visual patterns, using methods adapted from the study of vision in humans, scientists in York’s Department of Biology investigated the nervous systems of flies [...]
Contact with nature may mean more social cohesion and less crime Numerous studies have demonstrated the benefits of contact with nature for human well-being. However, despite strong trends toward greater urbanization and declining green space, little is known about the social consequences of such contact. In the December issue of BioScience, an international, interdisciplinary team reports on how they used nationally representative data from the United Kingdom [...]

Psychologists uncover what your musical taste says about your personality We’re exposed to music for nearly 20% of our waking lives. But much of our musical experience seems to be a mystery. Why does some music bring us to tears while other pieces make us dance? Why is it that the music that we like can make others agitated? And why do some people seem [...]
New study on mice finds new brain cell formation is enhanced by running Exercise can enhance the development of new brain cells in the adult brain, a process called adult neurogenesis. These newborn brain cells play an important role in learning and memory. A new study has determined that mice that spent time running on wheels not only developed twice the normal number of new neurons, but also [...]
Research into robot communication reveals why bartenders have to ignore some signals A robotic bartender has to do something unusual for a machine: It has to learn to ignore some data and focus on social signals. Researchers at the Cluster of Excellence Cognitive Interaction Technology (CITEC) of Bielefeld University investigated how a robotic bartender can understand human communication and serve drinks socially appropriately. For their new study, [...]
Researchers study willingness to adopt children with special needs Queen’s University researchers Philip Burge and Dianne Groll (Psychiatry) and two co-authors have just published a study regarding the attitudes and preferences of prospective adoptive parents. The study found that those who were most open to considering children with special needs had been formally seeking to adopt for some time and had completed government-required SAFE [...]
Peering into cell structures where neurodiseases emerge A latticework of tiny tubes called microtubules gives your cells their shape and also acts like a railroad track that essential proteins travel on. But if there is a glitch in the connection between train and track, diseases can occur. In the Proceedings of the National Academy of Sciences, Tatyana Polenova, professor of chemistry and [...]
Is Christmas creep making Black Friday a thing of the past? Black Friday is the “traditional” start of the holiday shopping season, when hordes of eager consumers line up outside retailers in the wee hours to ensure they don’t miss out on steeply discounted televisions, faded jeans and smartphones. Fistfights over printers are known to occur. But has Black Friday, which occurs the day after Thanksgiving, [...]

Explaining Americans' Reluctance to Accept Syrian Refugees The Syrian conflict has created the biggest humanitarian crisis since WWII yet over fifty percent of Americans oppose Syrian resettlement in the United States. Terror management theory, the principle of moral exclusion, and the study of prosocial behavior help explain why.

How cocaine changes the brain The burst of energy and hyperactivity that comes with a cocaine high is a rather accurate reflection of what's going on in the brain of its users, finds a study. Through experiments conducted in rats exposed to cocaine, the researchers mapped out the network of circuits that cause wild firing of neurons that produce dopamine. The findings also help explain how cocaine use eventually leads to desensitization.
