Mapping behavior in the fruit fly brain

One of the primary missions of neuroscience is to make connections between particular neurons in the brain and specific behaviors. Now a team of researchers has used computer-vision and machine-learning techniques in fruit flies to create behavior anatomy maps that will help us understand how specific brain circuits generate Drosophila aggression, wing extension, or grooming. "The ultimate...

Humans hardwired to lean to the right while kissing the world over

If you lean in for a kiss on the left you may be in the minority. A new study from an international team of psychologists and neuroscientists suggest that humans are hardwired to favour leaning to the right while kissing romantic partners, which may have wider implications for neuroscience and cognitive sciences. Building on previous...

Happiness can affect physical health

A new review indicates that subjective well-being -- factors such as life satisfaction and enjoyment of life -- can influence physical health. The review's investigators also examine why this is so and conditions where it is most likely to occur. Subjective well-being may exert its effects on physical health through health behaviors, as well as...

You’re not yourself when you’re sleepy

More than a third of Americans don't get enough sleep, and growing evidence suggests it's not only taking a toll on their physical health through heart disease, diabetes, stroke, and/or other conditions, but hurting their mental health as well. According to a recent study led by Postdoctoral FellowIvan Vargas, PhD, in the journal Cognitive Therapy and...

Brains are more plastic than we thought

Practice might not always make perfect, but it's essential for learning a sport or a musical instrument. It's also the basis of brain training, an approach that holds potential as a non-invasive therapy to overcome disabilities caused by neurological disease or trauma. Research at the Montreal Neurological Institute and Hospital of McGill University (The Neuro)...
