Brain 'relay' also key to holding thoughts in mind

Long assumed to be a mere "relay," an often-overlooked egg-like structure in the middle of the brain also turns out to play a pivotal role in tuning-up thinking circuity. A trio of studies in mice funded by the National Institutes ...

Neuronal circuits filter out distractions in the brain

The next time you are in a crowded room, or a meeting, or even at the park with your kids, take a look around. How many people are on their phone? Distractions invade every aspect of our lives. Status updates, text messages, ...

Distinguishing REM sleep from other conscious states

(Medical Xpress)—Despite decades of research, little is known about the function of REM sleep, or the dreams that often accompany it. Rapid eye movements occur in most mammals, with a few exceptions like echidnas and dolphins. ...

Neurons that encode sweetness identified in mice

Researchers from the National Institute for Physiological Sciences in Japan have identified the neurons responsible for relaying sweet taste signals to the gustatory thalamus and cortex in mice. While the peripheral taste ...

Discovery deepens understanding of brain's sensory circuitry

Because they provide an exemplary physiological model of how the mammalian brain receives sensory information, neural structures called "mouse whisker barrels" have been the subject of study by neuroscientists around the ...

Deep sleep critical for visual learning

Remember those "Magic Eye" posters from the 1990s? You let your eyes relax, and out of the tessellating structures, a 3-D image of a dolphin or a yin yang or a shark would emerge.

Scientists use ultrasound to jump-start a man's brain after coma

A 25-year-old man recovering from a coma has made remarkable progress following a treatment at UCLA to jump-start his brain using ultrasound. The technique uses sonic stimulation to excite the neurons in the thalamus, an ...
