|Enjoy Yourself... or Else!
||Everywhere we go we are bombarded with stimuli to keep us entertained. Do we have no right to silence?
|Glimpses of how the brain transforms sound
||When people hear the sound of footsteps or the drilling of a woodpecker, the rhythmic structure of the sounds is striking. Even when the temporal structure of a sound is less obvious, as with human speech, the timing still conveys a variety of important information. How such sounds are processed is now better understood.
|World Happiness Report 2015 ranks happiest countries
||Since it was first published in 2012, the World Happiness Report demonstrated that well-being and happiness are critical indicators of a nation's economic and social development, and should be a key aim of policy. This year's report looks at the changes in happiness levels in 158 countries, and examines the reasons behind the statistics.
|Scientists pinpoint brain-swelling mechanism
||A significant discovery has been made uncovering the cause of brain swelling after trauma to the head. The research paves the way for a preventative drug treatment for severe brain damage following stroke, infection, head injury or cardiac arrest.
|Brain tumor growth stimulated by nerve activity in the cortex, study finds
||Deadly brain tumors called high-grade gliomas grow with the help of nerve activity in the cerebral cortex, according to a new study. The work, conducted in mice with an aggressive human brain cancer implanted in their brains, is the first to demonstrate stimulation of tumor growth by brain activity.
|In search of tinnitus, that phantom ringing in the ears
||About one in five people experience tinnitus, the perception of a sound -- often described as ringing -- that isn't really there. Now, researchers have taken advantage of a rare opportunity to record directly from the brain of a person with tinnitus in order to find the brain networks responsible.
|Brain circuitry for selecting among sensations
||Neuroscientists show how cells in the brain's cortex can either stifle or enhance sensory information incoming from the thalamus, thereby allowing it to focus on just some of the many sensory inputs it might choose to consider.
|How to stop a stroke in its tracks
||New minimally invasive surgical devices called stentrievers are enabling brain surgeons to stop strokes in their tracks.
|Fat tissue controls brain's response to food scarcity, helping regulate optimal amount of body fat for brain function
||An enzyme secreted by the body's fat tissue controls energy levels in the brain, according to new research. The findings, in mice, underscore a role for the body's fat tissue in controlling the brain's response to food scarcity, and suggest there is an optimal amount of body fat for maximizing health and longevity. The findings may help explain the many studies that show a survival benefit to having a body mass index toward the low end of what is considered overweight.
|Extra sleep fixes memory problems in flies with Alzheimer's-like condition
||Many studies have linked more sleep to better memory, but new research in fruit flies demonstrates that extra sleep helps the brain overcome catastrophic neurological defects that otherwise would block memory formation, report scientists.
|For lower-grade brain blood vessel malformations, surgery has 'excellent clinical outcomes'
||Interventional treatments--especially surgery--provide good functional outcomes and a high cure rate for patients with lower-grade arteriovenous malformations (AVMs) of the brain, report researchers.

|Scientists create the sensation of invisibility
||The power of invisibility has long fascinated man and inspired the works of many great authors and philosophers. A team of neuroscientists now reports a perceptual illusion of having an invisible body, and show that the feeling of invisibility changes our physical stress response in challenging social situations.

|Tantrums, transmitters and treatments: Two neurotransmitters in key parts of the male mouse brain are linked to unusually aggressive behaviour and may lead to treatments for psychopathic behaviour in humans
||How do some of us manage to control our violent tendencies while others cannot? Research may help to address this question. International collaborators found that an increase in the levels of two neurotransmitters, glutamate and serotonin, in key parts of the brain is linked to intense aggression in male mice.
