Researchers confirm postpartum depression heritability, home in on treatment mechanism

Researchers have conducted a large-scale meta-analyses of genome-wide association studies (GWAS) to investigate the genetic architecture of PPD.

Study finds men’s antidepressant use did not negatively impact IVF success

In vitro fertilization (IVF) is a time-intensive and often stress-inducing fertility procedure. Yet how does that stress impact its success? Investigators have now assessed the effects of anxiety and depression in men on fertility and IVF outcomes.

Scientists explain how the brain encodes lottery values

Neuroscientists have uncovered a key brain area in rats that encodes the value of economic choices when faced with the uncertainty of a lottery. In this work, the causal role of frontal and parietal cortex was tested in economic decision-making. The fi…

Soft optical fibers block pain while moving and stretching with the body

New soft, implantable fibers can deliver light to major nerves through the body. They are an experimental tool for scientists to explore the causes and potential treatments for peripheral nerve disorders in animal models.

Converting brain immune cells into neurons helps mice recover after stroke

Researchers have discovered that turning brain immune cells into neurons successfully restores brain function after stroke-like injury in mice. These findings suggest that replenishing neurons from immune cells could be a promising avenue for treating …

Smarter CT scans may approach the level of MRI

In certain cases, a new method can provide as much information from brain images taken with computed tomography (CT) as images captured with magnetic resonance imaging (MRI). The method could enhance diagnostic support, particularly in primary care, fo…

Depression, anxiety common among college students

Depression and anxiety among college students is a growing public health problem. And new research suggests the problem may be worse for students who aren’t the same race as most of their peers. The new study found that students who were not the majori…

Brain connectivity is disrupted in schizophrenia

Schizophrenia, a neurodevelopmental disorder that features psychosis among its symptoms, is thought to arise from disorganization in brain connectivity and functional integration. Now, a new study finds differences in functional brain connectivity in p…

The emotional function of dreams is not the same everywhere

Why do we dream? A product of our brain’s neurophysiology, dreaming is a complex experience that can take on many emotional tones and simulate reality to varying degrees. As a result, there is still no clear answer to this question. A study compared th…

Researchers develop technology to tabulate and characterize every cell in the human brain

By combining non-invasive imaging techniques, investigators have created a comprehensive cellular atlas of a region of the human brain known as Broca’s area.
