Individual differences in the brain

If selection reinforces a behavior, brain activities soon change as well.

Gulf war illness, chronic fatigue syndrome distinct illnesses, study suggests

A brain imaging study of veterans with Gulf War illness (GWI) and patients with chronic fatigue syndrome (CFS) (sometimes called myalgic encephalomyelitis), has shown that the two illnesses produce distinctly different, abnormal patterns of brain activ…

Novel approach reduces SCA1 symptoms in animal model

Manipulating a novel mechanism that regulates ATXN1 levels reduced ATXN1 and improved some of the symptoms of neurodegenerative disease SCA1 in animal models.

Brain noise contains unique signature of dream sleep

Dream or REM sleep is distinguished by rapid eye movement and absence of muscle tone, but electroencephalogram (EEG) recordings are indistinguishable from those of an awake brain. Neuroscientists have now found an EEG signature of REM sleep, allowing s…

Placebos prove powerful even when people know they’re taking one

Researchers have demonstrated that placebos reduce brain markers of emotional distress even when people know they are taking one.

Key to dialogue between brain cells to protect against stroke

LSU Health New Orleans research has unlocked a key fundamental mechanism in the communication between brain cells when confronted with stroke and found DHA not only protected neuronal cells and promoted their survival, but also helped maintain their in…

Brain waves can be used to predict future pain sensitivity

Rhythms produced by the brain can reliably be used to predict how sensitive we are to pain, new research shows.

Scientists discover cells that filter and sharpen spatial signals

How do you keep orientation in a complex environment, like the city of Vienna? You can thank your brain’s ‘global positioning system’ (GPS), the hippocampus, for this sense of orientation. To further understand its functions, scientists have analyzed s…

REM sleep tunes eating behavior

Despite our broad understanding of the different brain regions activated during rapid-eye-movement sleep, little is known about what this activity serves for. Researchers have now discovered that the activation of neurons in the hypothalamus during REM…

Non-invasive nerve stimulation boosts learning of foreign language sounds

New research by neuroscientists revealed that a simple, earbud-like device that imperceptibly stimulates the brain could significantly improve the wearer’s ability to learn the sounds of a new language. This device may have wide-ranging applications fo…
