Smelling in tiny houses: How ciliary electric currents keep olfaction reliable

Scientists have used a combination of mathematical modeling, electrophysiology, and computer simulations to explain how cells communicate effectively in highly constricted spaces such as the olfactory cilia, where odor detection takes place. The findin…

Sound changes the way rodents sense touch

Researchers report how the somatosensory cortex interprets tactile and auditory stimulation in mice and rats. They show that the barrel cortex response to auditory and tactile stimuli is additive, but also with different electrophysiological properties…

Your brain rewards you twice per meal: When you eat and when food reaches your stomach

We know a good meal can stimulate the release of the feel-good hormone dopamine, and now a study in humans suggests that dopamine release in the brain occurs at two different times: at the time the food is first ingested and another once the food reach…

Online mirrors: Video bloggers and viewers share emotions

Examining over 2,000 video blogs, or vlogs on YouTube, researchers found we mirror the emotions of those we see online and seek out people who share our emotions.

How the brain enables us to rapidly focus attention

Researchers have discovered a key mechanism in the brain that may underlie our ability to rapidly focus attention. Our brains are continuously bombarded with information from the senses, yet our level of vigilance to such input varies, allowing us to s…

New insight on how memory works

Researchers have explored how memory is tied to the hippocampus, with findings that will expand scientists’ understanding of how memory works and ideally aid in detection, prevention, and treatment of memory disorders.

Kicking, yelling during sleep? Study finds risk factors for violent sleep disorder

Taking antidepressants for depression, having post-traumatic stress disorder or anxiety diagnosed by a doctor are risk factors for a disruptive and sometimes violent sleep disorder called rapid eye movement (REM) sleep behavior disorder. The study also…

Post-natal depression in dads linked to depression in their teenage daughters

Fathers as well as mothers can experience post-natal depression — and it is linked to emotional problems for their teenage daughters, new research has found.
