Neurosalience #S6E13 with Kristin Ozelli - The Transmitter: Connecting the scales of neuroscience
“The Transmitter is trying to cover the whole waterfront…”Kristin Ozelli is the Executive Editor of The Transmitter, a neuroscience publication supported by the Simons Foundation that launched in 2023. In this conversation, Peter and Kristin explore what makes The Transmitter tick. At its heart, the publication is driven by a conviction that neuroscience is most powerful when its many scales, modalities, and subfields are in conversation with each other, and that good science journalism can provide the intellectual scaffolding to make that happen. They discuss the editorial process behind the scenes, from morning story meetings and house style guides to multiple rounds of editing, and how scientist-written essays are helping fill the void left by the decline of science Twitter. The conversation also touches on The Transmitter's ambitious State of Neuroscience mapping project, the ongoing tension between a fragmenting field and the hunger for greater integration, and what it means to portray science as a genuinely human endeavor. They close with thoughts on AI in science writing, exciting new tools and resources coming to the site, and how publications like The Transmitter might help rebuild trust between scientists and a skeptical public.We hope you enjoy this episode!Chapters:00:00 - Introduction to the Transmitter and Its Mission05:49 - Kristin Ozelli’s Journey to Neuroscience Journalism08:29 - The Transmitter's History and Evolution11:03 - Finding the Sweet Spot in Neuroscience Communication16:19 - Mapping Neuroscience: The State of Neuroscience Project23:22 - Engaging the OHBM Community and Beyond30:07 - The Evolution of Scientific Communication33:45 - Public Perception of Science40:22 - Future Directions for Transmitter47:15 - The Role of AI in JournalismResources:14:20 - The State of Neuroscience https://www.thetransmitter.org/state-of-neuroscience-report-2025/Episode producers:Karthik Sama, Xuqian Michelle Li

Neurosalience #S6E11 with Alessandro Gozzi - Decoding connectivity: From mouse brains to human mind
"We inhibited a brain region and connectivity went up. I thought it was an artifact..."Dr. Alessandro Gozzi is a systems neuroscientist investigating how the brain functions as an integrated network and how disruptions in that network relate to behavior and mental health. He is Senior Scientist and Group Leader of the Functional Neuroimaging Laboratory at the Italian Institute of Technology in Rovereto, Italy. His research combines fMRI, functional ultrasound imaging, optogenetics, chemogenetics, electrophysiology, and computational modeling to decode the neural underpinnings of brain connectivity in rodent models, with the goal of bridging circuit-level findings to human psychopathology.In this conversation, Dr. Gozzi unpacks what resting-state fMRI connectivity actually reflects and why the answer may be more surprising than the field assumes. Drawing on a series of elegant chemogenetic and pharmacological manipulations in mice, he reveals how regional excitability, rather than direct synaptic communication, may be a dominant driver of the connectivity patterns we observe. Within this context, the conversation explores the paradoxical relationship between neural silencing and hyperconnectivity, the evolutionary conservation of brain networks across species, and what rodent models of autism can and cannot tell us about human psychiatric disorders. Join the conversation to discover how mechanistic animal studies are reshaping our understanding of human brain connectivity.We hope you enjoy this episode!Chapters:00:00 - Introduction to Dr. Alessandro Gozzi05:12 - Gozzi’s Unconventional Journey into Neuroscience13:17 - Transitioning from Industry to Academia20:49 - The Relevance of Rodent Models in Understanding Autism32:04 - Exploring the Complexities of Brain Connectivity38:57 - Excitability and Its Role in Connectivity Patterns42:27 - Exploring fMRI Connectivity and Local Computation45:28 - The Role of the Hearst Index in Brain Activity54:00 - Implications for Treatment in Psychiatric Disorders58:42 - The Intersection of Biology and Neuroscience Research01:07:08 - Balancing Life and Science: Personal ReflectionsWorks mentioned:00:12:48 - Gutierrez-Barragan, D. et al.

Neurosalience #S6E8 with Mario Senden - From rich clubs to mapping neuroscience itself
Dr. Mario Senden is an assistant professor in the Department of Cognitive Neuroscience at Maastricht University in the Netherlands, where he has spent his entire academic career. He received his bachelor's in psychology in 2009 and his PhD in cognitive computational neuroscience in 2016, both from Maastricht. A pioneer in biophysics-aware deep learning, Mario is known for his work on how large-scale brain networks support communication, integration, and perception. His research spans mesoscale laminar microcircuits to the macro-scale connectome, and his functional whole-brain modeling framework combines large-scale anatomical structure with local dynamics and goal-driven computation — asking not just whether a dynamical regime is biologically plausible, but whether it actually supports perceptual and cognitive function.In this episode, Peter and Mario explore the cutting edge of computational neuroscience and whole-brain modeling. They discuss Mario's influential work on rich club networks, which showed how highly connected cortical hubs dynamically gate information flow during tasks, as well as the principles behind oscillatory behavior in neural systems. A central focus of the conversation is Mario's most recent paper, "The Evolving Landscape of Neuroscience," submitted to Aperture Neuro — a sweeping meta-scientific analysis of roughly half a million neuroscience articles published between 1999 and 2023. Using text embeddings, semantic clustering, and large language models, Mario mapped the structural organization of the field and identified emerging trends and future directions. The conversation also touches on the promise of interdisciplinary approaches, the growing role of AI tools in neuroscience research, and the broader challenge of integrating theories and data across scales and domains to truly understand the brain.We hope you enjoy this episode!Chapters:00:00 - Introduction to Dr. Mario Senden05:11 - Journey from Psychology to Computational Neuroscience10:01 - Understanding Cognitive Computational Neuroscience14:09 - Limits of Current Models in Cognitive Computational Neuroscience20:44 - Exploring the Rich Club Concept in Brain Networks29:22 - The Interplay of Cortex and Subcortex42:44 - Oscillatory Behavior and Network Coordination48:41 - Multi-Scale Modeling in Neuroscience57:49 - Exploring the Evolving Landscape of Neuroscience01:21:08 - Advice for Young ScientistsWorks mentioned:42:19 - Senden et al.
