Researchers have identified 44 genetic risk factors for major depressive disorder. 30 of the variants are newly discovered. The team reports the genetic basis for MDD is shared with other psychological disorders and all humans carry some of the genetic risk factors identified.
Genetic analysis of almost 195,000 people helped researchers identify 50 novel genes associated with eye color.
A new study reveals the role basket cells play in navigation.
People who receive threatening or obscene text messages and other communications from current or former partners are more likely to experience mental health problems including depression and anxiety, and have an increased risk of suicidal thoughts.
Identical twins were more likely to have similar sun-seeking behaviors than non-identical twins, suggesting genetics play a key role in sun-seeking behaviors.

The risk of self-harm presenting to emergency rooms is three times higher for boys with ASD compared to those not on the autism spectrum. Additionally, researchers found a four-fold increase in self-harm behaviors for both males and females with ADHD. Children with less than 80% school attendance also had a three times higher risk of self-harming behaviors.
A new Lancet study reports auditory hallucinations may be reduced in people with schizophrenia following face-to-face discussions with an avatar that says the things they hear. Researchers report the patients were able to verbalize their feeling by 'standing up to' the avatars and taking control of the conversations.
Researchers from the Developing Human Connectome Project have released over 500 brain scans from newborn babies as part of an open-source effort to allow other researchers to study human brain development.
Theta activity in the brain is different following mistakes or challenging tasks in those with common mental health disorders including anxiety, ADHD, and OCD compared to those with no history of the disorders.
Brain scans revealed, compared to women with low risk for postpartum psychosis, new mothers in high-risk groups had altered brain connectivity in networks associated with goal-orientated behaviors.
