Dyslexia linked to shorter memory trace of previous stimuli

Researchers have provided new insight into the brain mechanisms underlying a condition that causes reading and writing difficulties.

In women, age-related cognitive decline may start sooner than we think

Researchers from University of California, Los Angeles reveal that, at least in women, cognitive decline may begin earlier that previously believed.

Novel radiotracer measures olfactory neurons in animal models

Olfactory health – how well we are able to smell — is a reliable marker of the health of the brain, but current ‘smell identification tests’ do not offer a complete picture of the situation. Using a novel PET radiotracer researchers have found a way t…

Brain abnormalities in fetuses exposed to Zika

Researchers have completed a characterization of brain malformations and volume assessment in fetuses with Zika Virus infection using MRI.

Hormone can enhance brain activity associated with love and sex

The hormone kisspeptin can enhance activity in brain regions associated with sexual arousal and romantic love, according to new research.

Potential way to reduce drug cravings: Vagus nerve stimulation therapy

A new preclinical study shows that vagus nerve stimulation therapy might have the potential to help people overcome drug addiction by helping them learn new behaviors to replace those associated with seeking drugs.

Novel underlying mechanism involved in PTSD and other anxiety disorders described

A novel mechanism has been identified for how stress-induced anxiety — which can produce post-traumatic stress disorder, or PTSD — affects circuit function in the hippocampus, the area of the brain where aversive memories are formed. These studies fi…

Nicotine normalizes brain activity deficits that are key to schizophrenia

A steady stream of nicotine normalizes genetically-induced impairments in brain activity associated with schizophrenia, according to new research. The finding sheds light on what causes the disease and why those who have it tend to smoke heavily.

Where belief in free will is linked to happiness

Free will describes the ability to make independent choices, where the outcome of the choice is not influenced by past events. In this study, researchers show that Chinese teenagers who believe in free will also show increased happiness, suggesting tha…

Network of molecular interactions in brain cells infected by Zika virus reveals new therapeutic targets

Zika virus interferes with the cellular machinery controlling cell division and alters the expression of hundreds of genes responsible for guiding the formation and development of brain cells, according to new research findings.
