In this podcast authors, Dr. Lee Miller and Mr. Christopher Versteeg talk with our guest host, Associate Editor Professor Robert Brownstone, about their recently published article on “Encoding of limb state by single neurons in the cuneate nucleus of awake monkeys.” The cuneate nucleus (CN) is the somatosensory gateway i...

The Journal of Neurophysiology would like to dedicate the following podcast to Dr. Richard Gray. Dr. Gray passed away at the age of 68 on September 4, 2021.  How are potassium channels regulated? How ubiquitous are sodium-dependent potassium channels? In this podcast Editor-in-Chief Professor Nino Ramirez and authors Drs. Richard Gray and Daniel Johnston discuss their manuscript titled  “Sodium se...

Auditory and visual information are processed differently by the brain, especially when it comes to space.  In vision, the retina senses the locations of images with respect to where the eyes are pointing.  In hearing, the cues our brains use to localize sound tell us where the sound is positioned with respect to the head and ears.  How then do we perceive space as unified? In particular, how do o...

In this podcast Editor in Chief Nino Ramirez and Associate Editor Prof. John Krakauer discuss JNP’s new manuscript type the Neurocene. The Neurocene is a narrative that explores accelerating developments in the field of neuroscience, placing them in their historical and present context. Authors should provide a personalized and thoughtful viewpoint of a topic that does not seek to either provide d...

In this podcast Editor in Chief Nino Ramirez and senior author, Professor Haouzi of Pennsylvania State University discuss the paper titled “Respiratory effects of low and high doses of fentanyl in control and β-arrestin 2 deficient mice”. When life-threatening doses of fentanyl are used in mice, the beta-arrestin2 pathway appears to play a critical role in the recovery from an opioid overdose. Thi...

 What is sensorimotor adaptation? Why do the authors use this term rather than motor learning? What are some of the key features of sensorimotor adaptation, and in particular, why is the focus here on error-based learning? How do the author's results change the way we think about how visual uncertainty impacts adaptation?   Out of the University of California, Professor Richard Ivry and JT Tsay di...

What features of a sound does the brain perceive as a pitch? What is the role of rhythm in music?  In this podcast Dr. Nancy Kanwisher ( Massachusetts Institute of Technology) and PhD candidate Dana Boebinger (Harvard University) discuss how music-selective neural populations are clearly present in people without musical training, demonstrating that they are a fundamental and widespread property o...

In this podcast Editor in Chief Nino Ramirez discusses JNP’s new article type Neurovision with Prof. John Krakauer of Johns Hopkins University and Prof. Reza Shadmehr of Johns Hopkins University. Neurovision articles aim to move science forward and point out bottlenecks in our understanding of the field. They resemble review articles, but with the inclusion of original data. The presence of new or...

In this podcast Dr. Greg Horwitz of the University of Washington discuses double-opponent cells in macaque area V1, a class of neurons that respond to spatial chromatic contrast in visual scenes. What information they carry is debated because their receptive field organization has not been characterized thoroughly. Using white noise analysis and statistical model comparisons, De and Horwitz show t...

In this episode Editor in Chief Prof. Ramirez is joined by Prof Stroh of the University of Mainz and Prof. Totah of the University of Helsinki to discus the manuscript titled "Synchronous spiking associated with prefrontal high gamma oscillations evokes a 5 Hz-rhythmic modulation of spiking in locus coeruleus." Prof. Nelson Totah highlights the main conceptual advances in their paper and talks abo...

The topographic organization of skilled movements seem to be particularly plastic. The author describes how they addressed this issue in their study, and what methods they used. The motor cortex is topographically organized into maps of different body parts. We used to think that the function of motor cortex was to drive individual muscles, but more recently we have learned that it is also organiz...

What does it take to recover walking after a spinal cord injury? If you could replicate this supraspinal control – what aspects would you need? In this podcast Prof Sten Grillner talks about the spinal mechanisms that coordinate locomotion and the interaction between the different sensory mechanisms that help coordinate the locomotor movements and the central locomotor network.   Sten Grillner  ht...

In this podcast, Editor-in-Chief, Nino Ramirez talks with Dr. Marc Schmidt (University of Pennsylvania) about his Research Article which explores recent theories of norepinephrine (NE) function regarding the stimulation of the norepinephrine function that NE can act directly on the motor system to influence the transition between exploratory and exploitative behavioral strategies.  Learn how the s...

Have you ever wondered how the brain encodes information? How do you crack a code produced within the brain? What are the changes in practicing and performing during development and aging? In this podcast the authors talk about the differences between practice and performance. Be sure to listen to the end for our special guest.   S. E. Palmer,  B. D. Wright, A. J. Doupe, and M. H.
