Human brain houses diverse populations of neurons, new research shows A team of researchers has developed the first scalable method to identify different subtypes of neurons in the human brain. The research lays the groundwork for “mapping” the gene activity in the human brain and could help provide a better understanding of brain functions and disorders, including Alzheimer’s, Parkinson’s, schizophrenia and depression. By isolating and [...]
Long visits to nature linked to improved mental health, study finds People who visit parks for 30 minutes or more each week are much less likely to have high blood pressure or poor mental health than those who don’t, according to new research by Australian and UK environmental scientists. A study led by The University of Queensland (UQ) and the ARC Centre of Excellence for Environmental [...]
New research uncovers why an increase in probability feels riskier than a decrease Probability estimates are constantly changing. A 20 per cent chance of rain suddenly goes to 30 per cent and we start thinking about packing an umbrella. But how differently do we react when a forecast goes from a 40 per cent chance of rain down to 30? According to a new U of T study, [...]
Healing Sexual Abuse I counsel a young woman who was sexually abused by a family member when she was 7-years young. The way she has dealt with the abuse is unlike any other … ...
Scientists reveal single-neuron gene landscape of the human brain A team of scientists has completed the first large-scale assessment of single neuronal 'transcriptomes.' Their research reveals a surprising diversity in the molecules that human brain cells use in transcribing genetic information from DNA to RNA and producing proteins.
Heroin use in U.S. reaches "alarming" high Two new reports highlight huge spikes in both heroin and opioid painkiller abuse.

Buying Local Food Won't Save the Planet We are all concerned about the environment and about what life will be like for generations yet unborn. So the idea of local sourcing is becoming very popular.
Your Self-Driving Car Will Be Programmed to Kill You—Deal With It A recent survey shows that people want self-driving cars to be programmed to minimize casualties during a crash, even if it causes the death of the rider. Trouble is, the same survey shows that people don’t actually want to ride in cars that are programmed this way. That’s obviously a problem—and we’re going to have to get over it....
Sleight of mind in fMRI I’ve written a piece for the BPS Research Digest about a fascinating study that caused people to feel their thoughts were being controlled by outside forces. It’s a psychologically intriguing study because it used the psychology lab to conduct the study but it also used the psychology lab as a form of misdirection, so participants … Continue reading "Sleight of mind in fMRI"
Precise control of brain circuit alters mood By combining super-fine electrodes and tiny amounts of a very specific drug, researchers have singled out a circuit in mouse brains and taken control of it to dial an animal's mood up and down. Stress-susceptible animals that behaved as if they were depressed or anxious were restored to relatively normal behavior by tweaking the system, according to a study.
New study provides unprecedented insight into the fine details of neuronal communication For communication between neurons to occur, an electrical impulse, called an action potential, must travel down an axon to its synaptic terminal. A major technical challenge impeding the direct examination of this process, axonal excitability, is the small diameter of a typical axon -- less than 500 nanometers. Researchers have now optimized optical and electrophysiological recordings from single neurons to study axonal excitability with unprecedented detail.
Not only trauma but also the reversal of trauma is inherited Behaviors caused by traumatic experiences in early life are reversible. Researchers could demonstrate that environmental enrichment allows trauma-related symptoms in mice to be reversed. This is the first evidence that positive environmental factors can correct behavioral alterations which would otherwise be transmitted to the offspring. The symptoms and their reversal are associated with epigenetic regulation of the glucocorticoid receptor gene.
How Do You Know that You’re with the Right Person? At some point in most relationships, people ask themselves the same question, “Is this one the right person for me?” Whether you’re brand new or seven years in, it’s an inevitable question in most relationships. The question isn’t necessarily born out of doubt or insecurity. … ...
Skilled Performance Takes More Than Practice There has been a big debate in psychology about whether elite performance reflects talents or skills. A new meta-analysis helps to resolve this question.
Scientists learn more about how star-shaped brain cells help us learn A molecule that enables strong communication between our brain and muscles appears to also aid essential communication between our neurons, scientists report.
