Having an audience makes your brain perform better

New research examines what goes on in the brain when people perform a task in front of an audience versus when they are not being watched.

Animal study connects fear behavior, rhythmic breathing, brain smell center

There’s increasing physiological evidence connecting breathing patterns with the brain regions that control mood and emotion. Now researchers have added neurons associated with the olfactory system to the connection between behavior and breathing. Conn…

When there’s an audience, people’s performance improves

Often people think performing in front of others will make them mess up, but a new study found the opposite: being watched makes people do better.

A waking nightmare: The enigma of sleep paralysis

In sleep paralysis, your mind wakes up, but your body does not. You may also experience frightening hallucinations. What is this, and how can we cope?

Compound improves stroke outcome by reducing lingering inflammation

An experimental compound appears to improve stroke outcome by reducing the destructive inflammation that can continue months after a stroke, scientists report.

New ‘brain health index’ can predict how well patients will do after stroke

A new computer program can assess whole brain deterioration and help predict cognitive function after stroke up to ten times more accurately than current methods.

3-D human ‘mini-brains’ shed new light on genetic underpinnings of major mental illness

Researchers are leveraging gene-editing tools and mini-organs grown in the lab to study the effects of DISC1 mutations in cerebral organoids — ‘mini brains’ — cultured from human stem cells.

Neurons derived from super-obese people respond differently to appetite hormones

Scientists have successfully generated hypothalamic-like neurons from human induced pluripotent stem cells (hiPSCs) taken from the blood and skin cells of super-obese individuals and people with a normal body weight. The researchers found that the brai…

Scientists identify connection between dopamine and behavior related to pain and fear

Scientists have for the first time found direct causal links between the neurotransmitter dopamine and avoidance — behavior related to pain and fear. Researchers have long known that dopamine plays a key role in driving behavior related to pleasurable…

Machine-learning system processes sounds like humans do

Using a machine-learning system known as a deep neural network, researchers have created the first model that can replicate human performance on auditory tasks such as identifying a musical genre. This type of model can shed light on how the human brai…
