Featured articles can cover neuroscience, brain research, regenerative medicine, psychology, genetics, robotics, neurology and many other cognitive science topics. Featured neuroscience articles are articles that we believe to be very important, or that our readers will most likely want to read. Featured articles usually include an image and tend to be shared more across the social networks.
Findings may explain how neurodegenerative diseases spread throughout the brain and disrupt normal functions. Additionally, treatment for one disease could possibly work for the other two also.
Researchers report the frontoparietal network plays a key role in why humans have superior reasoning skills.
Neural progenitor cells generated from skin cell samples of people on the autism spectrum had heightened levels of DNA damage. The damage clustered in 36 of the same genes which had also been damaged in healthy cells exposed to replication stress. Twenty of the genes have previously been linked to the development of autism.
According to researchers, anxiety response is not only seen in areas associated with emotion, but also in brain areas associated with movement.
Spontaneous waves neuronal activity bear imprints of earlier events for at least 24 hours after the experience has taken place, a new study finds.
Following a potentially life-threatening event, people often report seeing their "lives flashing before their eyes", where a multitude of memories from life events are recalled almost instantaneously. Researchers present theories on why this phenomenon may occur.
The cognitive cost of empathy may cause people to be less empathetic to others.
A new study reports blocking specific ADAM enzymes can stop the growth and spread of glioblastoma brain cancer.
According to researchers, people with insomnia are more likely to report thoughts of death and suicide during a 30 day period than those who don't suffer from sleep disturbances.
A new neuroimaging study reveals people who consider themselves to be egotistical have no increased activity in the ventromedial prefrontal cortex when they think about the distant future. By contrast, altruistic people have increased activity in this region when asked to consider the consequences of the distant future.
Significantly more DNA sequences repeat in people with schizophrenia than in control individuals, a new study reports.
