In a study published today in the journal Trends in Cognitive Sciences, Prof. Moshe Bar, a neuroscientist at the Gonda (Goldschmied) Multidisciplinary Brain Research Center at Bar-Ilan University (BIU), together with Noa … Read more State of mind: The end of personality as we know it

Light therapy holds promise for people with bipolar disorder

Light therapy, consisting of daily exposure to bright, artificial light, is already a recognized line of treatment for people affected by seasonal and nonseasonal depressive disorder.

Researchers from the University of British Columbia analyzed data for 678,000 adults in Metro Vancouver. They found that living less than 50 metres from … Read more Living near major roads linked to increased risk of dementia, Parkinson’s, Alzheimer’s and MS

Visual neurons don’t work the way scientists thought, study finds

A new survey of the activity of nearly 60,000 neurons in the mouse visual system reveals how far we have to go to understand how the brain computes. Published today in the international journal Nature Neuroscience, the analysis led by researchers at the Allen Institute reveals that more than 90% of neurons in the visual cortex, the part … Read more Visual neurons don’t work the way scientists thought, study finds

Key mystery about how the brain produces cognition is finally understood

We explain human behavior in terms of unseen entities such as motivation, curiosity, anxiety, and confidence. What has been unclear, until now, is whether these mental entities are coded by specific neurons in specific areas of the brain. Professor Adam Kepecs at Cold Spring Harbor Laboratory answers some of these questions in new research published … Read more Key mystery about how the brain produces cognition is finally understood

Why stress doesn’t always cause depression

Rats susceptible to anhedonia, a core symptom of depression, possess more serotonin neurons after being exposed to chronic stress, but the effect can be reversed through amygdala activation, according to new research in JNeurosci. Some people are resistant to depression and anhedonia, or lack of pleasure, even when exposed to chronic stress. To measure susceptibility to … Read more Why stress doesn’t always cause depression

Comparative genetic architectures of schizophrenia in East Asian and European populations

As we all know, schizophrenia is a debilitating psychiatric disorder with prevalence of about ~1% lifetime risk across different populations. However, previously literatures mainly reported in European populations and the results remained ungeneralizable. The present study has explored the biological insights of schizophrenia in the largest sample size of East Asian populations up to now. … Read more Comparative genetic architectures of schizophrenia in East Asian and European populations

2/3 of parents cite barriers in recognizing youth depression

Telling the difference between a teen’s normal ups and downs and something bigger is among top challenges parents face in identifying youth depression, a new national poll suggests. Though the majority of parents say they are confident they would recognize depression in their middle or high school aged child, two thirds acknowledge barriers to spotting … Read more 2/3 of parents cite barriers in recognizing youth depression

Inactivity linked to teen suicide risk in developing countries

Not enough physical activity and too much sitting and screen-time have been linked with suicidal thoughts and behaviours in adolescents in developing countries, in a University of Queensland-led study. UQ School of Health and Rehabilitation Sciences researcher Associate Professor Asad Khan said suicide-related issues had become a major public health challenge in low and middle … Read more Inactivity linked to teen suicide risk in developing countries

Evidence that tobacco smoking increases risk of depression and schizophrenia

A new study published today [6 Nov] in Psychological Medicine and led by University of Bristol researchers has found that tobacco smoking may increase your risk of developing depression and schizophrenia. It is well known that smoking is much more common amongst people with mental illness – especially depression and schizophrenia. However, most studies that have looked … Read more Evidence that tobacco smoking increases risk of depression and schizophrenia
