Are Our Mouths Coupled to Our Ears?
News   Mar 05, 2019

How is our speech shaped by what we hear? The answer varies, depending on the make-up of our brain’s pathways, a team of neuroscientists has found. The research, which maps how we synchronize our words with the rhythm of the sounds we hear, offers potential methods for diagnosing speech-related afflictions and evaluating cognitive-linguistic development in children.

Bachelor Pod: Male Dolphins Group Together When Wooing Females
News   Mar 05, 2019

When it comes to wooing the ‘ladies’, it turns out male bottlenose dolphins seem to employ similar tactics to some human groups. Researchers studying dolphins in southern Australia found they form strong bonds with other male relatives in their social circle to improve their success rate when breeding with a small number of available females.

Protein Spring Helps Our Brain Recognize Sound
News   Mar 04, 2019

The inner ear cells are arranged to transmit sound to the brain, but just slight defects in these patterns can lead to deafness. Over 100 mutations in proteins involved in this intricate system have been associated with hearing loss. New research reveals how one of these proteins acts as a molecular spring that helps convert sound waves into an electrical signal that the brain can recognize.

Open-Source Software Tracks Neural Activity in Real Time
News   Mar 01, 2019

Tracking the firings of individual neurons has, until recently, been an arduous process that forces neuroscientists to tediously track each neuron by hand. A breakthrough software tool called CaImAn automates tracking using a combination of standard computational methods and machine-learning techniques.
