Between-hand coupling during response inhibition

Between-hand coupling during response inhibition

September 18, 2019

The "interference effect" occurs during a bimanual response when one hand is abruptly cued to stop, resulting in a significant delay in the actions of the other hand. But what neural mechanisms underlie this effect? In this podcast, Editor-in-Chief Bill Yates talks with Corey Wadsley, Dr. John Cirillo, and Dr. Winston Byblow (all from the University of Auckland) about their recent article, which investigates whether the interference effect is the consequence of between-hand coupling. Listen to learn about the role of GABA-mediated networks, movement preparation, paradoxical findings and more!

Pairing vagus nerve stimulation with tones drives plasticity across the auditory pathway

Pairing vagus nerve stimulation with tones drives plasticity across the auditory pathway

September 12, 2019

Previous studies have reported primary auditory cortex plasticity following vagus nerve stimulation (VNS) paired with a sound. Does this phenomenon extend to other fields in the auditory pathway? In this podcast, Editor-in-Chief Bill Yates talks with Dr. Michael S. Borland and Dr. Crystal Engineer (both from the University of Texas at Dallas) about their recent study, which is the first to to document both cortical and subcortical plasticity following VNS-sound pairing. Listen to learn about auditory plasticity, potential therapies for auditory processing disorders, and more!

Cannabinoid receptor-mediated modulation of inhibitory inputs to mitral cells in the main olfactory bulb

Cannabinoid receptor-mediated modulation of inhibitory inputs to mitral cells in the main olfactory bulb

September 4, 2019

What is the role of cannabinoid receptor type 1 (CB1) in olfactory processing? In this podcast, Editor-in-Chief Bill Yates talks with Thomas Heinbockel (Howard University) and Alex Straiker (Indiana University, Bloomington) about their recent study in mice, which revealed that CB1 is involved in the regulation of glomerular activity in the main olfactory bulb (MOB). Listen to learn about the endocannabinoid system, mitral cells, implications for olfactory behavior, and more!

Somatosensory interactions reveal feature-dependent computations

Somatosensory interactions reveal feature-dependent computations

May 28, 2019

Our ability to perceive and discriminate textures is based on the processing of high-frequency vibrations generated on the fingertip as it is scanned across a surface. But how do we process tactile information when we simultaneously experience different cues at separate locations on the body? In this podcast, Editor-in-Chief Bill Yates talks with Jeff Yau about his recent study which found that vibrations experienced on one hand always systematically modulated the perception of vibrations on the other hand. Listen to learn about somatosensory interactions, the role of hand position in tactile perception, and more!

Stable memory and computation in randomly rewiring neural networks

Stable memory and computation in randomly rewiring neural networks

May 23, 2019

Our brains must maintain a representation of the world over a period of time much longer than the typical lifetime of the biological components producing that representation. How does the brain handle this challenge at the synaptic level? In this podcast, Editor-in-Chief Bill Yates talks with Dan Acker about his recent study that tackled this question. Listen to learn about the importance of synaptic strength, modeling memory processes, and applications for machine learning!

Beyond the sleep-amyloid interactions in Alzheimer’s disease pathogenesis

Beyond the sleep-amyloid interactions in Alzheimer’s disease pathogenesis

May 9, 2019

Numerous studies have linked disrupted sleep and circadian rhythms with amyloid-β (Aβ), a key pathological hallmark in Alzheimer's disease (AD). While previous evidence suggests that Aβ initiates AD pathogenesis, tau, another major hallmark of AD, seems to drive neurodegeneration. Recent studies imply that sleep-wake cycles affect brain tau more significantly than Aβ levels, leading to accelerated AD progression and cognitive decline. In this podcast, Editor-in-Chief Bill Yates talks with Shen Ning (Boston University; Genetics and Aging Research Unit, Mass General and Harvard) and Mehdi Jorfi (Mass General and Harvard) about their NeuroForum article, which discusses the importance of these recent findings.
