Electric fish helps scientists understand how the brain filters out internal stimuli
July 11 (UPI) -- Without the brain's noise-cancellation capabilities, life would be too disorienting. The ability to filter out internal stimuli is essential to our ability to process the world around us. Scientists at Columbia University have ...

A transgenic mouse for imaging activity-dependent dynamics of endogenous Arc mRNA in live neurons
The correlation of stimulation with Arc transcription and mRNA transport in individual neurons revealed that stimulus-induced Ca2+ activity was necessary but not sufficient for triggering Arc transcription and that blocking neuronal activity did not ...

Battling Crohn's Disease with Vagus Nerve Stimulation
Four times a day, 29-year-old Kelly Owens holds a magnet over her chest, activating an implanted device that sends gentle electrical pulses up to a large group of nerve fibers in her neck. It makes her voice a little shaky while the stimulation is on ...

Study reveals missing drivers of ocean deoxygenation
"We need multidisciplinary process studies to better understand the delicate balance of oxygenation and oxygen consumption in the ocean," said researcher Andreas Oschlies. By improving oxygen deoxygenation models, scientists would also be able to ...

Scientists discover bees understand the concept of zero
Trained to pick the lowest number out of a series of options, a honeybee chooses a blank image, revealing an understanding of the concept of zero. Credit: RMIT University. But bee brains have fewer than 1 million neurons—compared with the 86,000 ...
