The Lancet: Simpler, cheaper psychological treatment as effective as cognitive behavioural therapy for treating depression

A simple and inexpensive psychotherapy or talking therapy known as behavioural activation (BA) is as effective at treating depression in adults as the gold-standard cognitive behavioural therapy…

Brain activity, response to food cues differ in severely obese women, study shows

The brain’s reward centers in severely obese women continue to respond to food cues even after they’ve eaten and are no longer hungry, in contrast to their lean counterparts, according to a recent study.

Lack of sleep increases a child’s risk for emotional disorders later

Children who experience inadequate or disrupted sleep are more likely to develop depression and anxiety disorders later in life according to recent research. The study seeks to determine the precise ways inadequate sleep in childhood produces elevated …

Gastrointestinal disorders involve both brain-to-gut and gut-to-brain pathways

New research indicates that in patients with irritable bowel syndrome (IBS) or indigestion, there is a distinct brain-to-gut pathway, where psychological symptoms begin first, and separately a distinct gut-to-brain pathway, where gut symptoms start fir…

Does the immune system influence our social behavior?

Until recently, the immune system and brain were considered entirely separate systems. New work shows that they are even more entwined than first thought.

Urocortin-3: A signaling molecule for making friends

Meeting new people can be both stressful and rewarding. Research at the Max Planck Institute of Psychiatry, reported in Nature Neuroscience, suggests that a molecule involved in regulating stress…

Neural networks: Why larger brains are more susceptible to mental illnesses

In humans and other mammals, the cerebral cortex is responsible for sensory, motor, and cognitive functions. A new study shows that the global architecture of the cortical networks in large-brained primates and small-brained rodents is organized by com…

Researchers temporarily turn off brain area to better understand function

Capitalizing on experimental genetic techniques, researchers have demonstrated that temporarily turning off an area of the brain changes patterns of activity across much of the remaining brain.

How the brain improves motor control

Adaptation in reaching — gradual improvement of motor control in response to a perturbation — is a central issue in motor neuroscience. However, even the cortical origin of errors that drive adaptation has remained elusive. Scientists have now shown …

Cerebrospinal fluid signals control the behavior of stem cells in the brain

The choroid plexus, a largely ignored structure in the brain that produces the cerebrospinal fluid, is an important regulator of adult neural stem cells, research indicates. The study also shows that signals secreted by the choroid plexus dynamically c…
