From Songbird Science to Salsa Dancing

Posted on by

Erich Jarvis spends his days at the Rockefeller University, New York, studying songbirds and searching for clues about the origins of language. But at least two nights a week, you won’t find this highly accomplished neurobiologist mulling over the latest neuroscience results or shooting an email to colleagues about their ongoing efforts to sequence bird genomes. He’ll be in the dance studio, practicing his latest salsa dancing moves.

In fact, before even considering a career as a scientist, Jarvis was a dancer. He danced ballet in grade school, later enrolling in New York’s High School of the Performing Arts as a dance major. Between academic classes, he spent three hours each day practicing ballet at school and, as a teen, another three hours each night practicing solos and pas de deux at the renowned Joffrey Ballet School and, later, the Alvin Ailey American Dance School. Jarvis even received an invitation as a high school senior to audition for the Alvin Ailey American Dance Theater.


How the Brain Regulates Vocal Pitch

Whether it’s hitting a high note, delivering a punch line, or reading a bedtime story, the pitch of our voices is a vital part of human communication. Now, as part of their ongoing quest to produce a dynamic picture of neural function in real time, researchers funded by the NIH’s Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative have identified the part of the brain that controls vocal pitch [1].

This improved understanding of how the human brain regulates the pitch of sounds emanating from the voice box, or larynx, is more than cool neuroscience. It could aid in the development of new, more natural-sounding technologies to assist people who have speech disorders or who’ve had their larynxes removed due to injury or disease.


LabTV: Curious About Sleep Disorders

Ketema Paul
Ketema Paul remembers being wowed at an early age by his cousin’s chemistry set and always feeling drawn to science. This interest followed him to Howard University, Washington, D.C., where he earned an undergraduate degree in biology, and on to Georgia State University, Atlanta for his Ph.D. Now, an associate professor at Atlanta’s Morehouse School of Medicine and the subject of our latest LabTV video, Paul runs his own neuroscience lab studying sleep disorders, which affect at least 60 million Americans as chronic or occasional problems and account for an estimated $16 billion in medical costs each year [1].

Paul’s path to the research bench is an interesting one. The product of a tough neighborhood in Washington, D. C., Paul lost a lot of friends to violence and faced many uncertainties. After college, he moved to Atlanta to try his hand at being a music producer and eventually took a side gig as a disc jockey for the campus radio station at Georgia State. Then one day after his radio show, Paul wandered over to have a look inside a nearby neuroscience lab just for kicks and opened the door on a discussion that would change his life.


Vision Loss Boosts Auditory Perception

Many people with vision loss—including such gifted musicians as the late Doc Watson (my favorite guitar picker), Stevie Wonder, Andrea Bocelli, and the Blind Boys of Alabama—are thought to have supersensitive hearing. They are often much better at discriminating pitch, locating the origin of sounds, and hearing softer tones than people who can see. Now, a new animal study suggests that even a relatively brief period of simulated blindness may have the power to enhance hearing among those with normal vision.

In the study, NIH-funded researchers at the University of Maryland in College Park, and Johns Hopkins University in Baltimore, found that when they kept adult mice in complete darkness for one week, the animals’ ability to hear significantly improved [1]. What’s more, when they examined the animals’ brains, the researchers detected changes in the connections among neurons in the part of the brain where sound is processed, the auditory cortex.
