Investigating the neurological pathways underlying vocal communication

Talking Techniques

In this episode of Talking Techniques, we catch up with Michael Long, Principle Investigator of the Long Lab at New York University (NY, USA), where he investigates the neural circuits that underlie vocal communication.

Through the examination of animal models, from songbirds to the rare singing mice of Costa Rica, with cutting-edge imaging techniques Michael reveals fascinating insights into vocal communication. We also discuss his human experiments, working alongside neurosurgeons, with emerging electrophysiological probes to monitor the neural activity of participants as they speak and interact, ultimately revealing how this research could begin to provide solutions for neurological conditions impacting communication, such as autism.
