Synchronized Neurons Focus Attention

According to a study published recently in Nature, neurons firing synchronously help to focus the brain’s attention on certain tasks and lead to quicker response times. When neurons fire independently their electrical output is nothing but noise, and no coherent signal is discernible in the static. When even a few neurons fire synchronously, their individual …

Neurons That Tune Out Background Noise

LiveScience.com is reporting that researchers from the University of Washington have discovered neurons in the brainstems of rats whose sole function is to identify new sounds while ignoring ongoing and predictable background noises. The scientists believe these specialized neurons are present in all vertebrates, including humans in whom they probably play a significant role in …
