Wireless Recording and Stimulation Technologies for in vivo Electrophysiology in Conscious, Freely Behaving Rodents

Wireless Recording and Stimulation Technologies for in vivo Electrophysiology in Conscious, Freely Behaving Rodents

Scientists discuss technological advancements and present novel application of new head-mounted and implantable, wireless sensors for neural recording and stimulation in freely moving animals.   

During this webinar, sponsored by Triangle BioSystems International (TBSI), scientists present experimental methods and scientific findings from applications of in vivo electrophysiology in freely moving rodents using new head-mounted, wireless sensors.

Specifically, Dr. Melissa Caras and Dr. Dan Sanes  from the Centre for Neural Science at New York University, present a case study on auditory cortex recordings collected from freely moving gerbils during learning and task performance. They share methodology, resulting discoveries, and discuss the importance of within-animal, real-time comparisons of neural and behavioral measures. Following, Bradly Barth presents experimentation conducted in Dr. Xiling Shen’s laboratory at Duke University, where they have achieved successful stimulation of the sacral nerve in conscious, freely-moving, untethered mice using a hermetic, fully-implantable, wireless nerve stimulator from TBSI.

Scientists from The Hatsopoulos Lab at the University of Chicago present research using a 64 channel wireless headstage on marmosets.  The group discusses the platform they have developed for voluntary behavioural training and neural recording in a home cage environment, and shares preliminary data they are using to investigate sensorimotor encoding across the marmoset’s behavioral repertoire. Following representatives from Dr. Ben Hayden’s lab from the University of Minnesota present a case study in which they have successfully implemented the 128-channel headstage in macaques while performing a center-out joystick task in a primate chair. They share methodology, experimental design, and discuss the promise their results show for future studies using untethered wireless recordings in freely moving and behaving animals.  WATCH ON DEMAND

Melissa Caras, PhD

Postdoctoral Associate,
Sanes Lab – Center for Neural Science,
New York University

Melissa Caras is a postdoctoral associate in the Sanes Lab at the Center for Neural Science, NYU. Her research examines how auditory perception changes as a function of experience, and explores the neural mechanisms that support this plasticity. She has investigated this topic using several paradigms, including the effects of hormonal fluctuations and the consequences of developmental hearing loss. Currently, she uses cutting-edge methodologies to explore the neural mechanisms of auditory perceptual learning.

Dan Sanes, PhD

Professor of Neural Science and Biology,
Center for Neural Science,
New York University

Dan Sanes is a professor of Neural Science and Biology at the Centre for Neural Science, NYU. He has been cited in over 100 articles, 9 peer-reviewed chapters, and 4 books. His lab studies the development and function of brain circuits that encode auditory cues, and the emergence of adult perceptual skills at both the cellular and systems levels. Ultimately, they seek to understand how the development and plasticity of synaptic and membrane properties permit networks to properly encode auditory cues, thereby supporting adult perceptual skills.

Bradley Barth

PhD Candidate,
Dr. Xiling Shen Lab,
Duke University

Bradley Barth is a PhD candidate in the Shen laboratory at Duke University. He studies the neural control of motility in the gastrointestinal system with in vivo electrophysiology and electrical stimulation. Bradley develops new devices and techniques to assess function and disease in the gut. He then builds predictive computational models of neuromuscular motility and applies these predictive models to improve neuromodulation therapies for functional gastrointestinal disorders.
