Using chronic calcium imaging in mouse auditory cortex, we show that during this representational drift signal correlations predict future noise correlations, suggesting that stimulus-driven co-activation strengthens effective connectivity via Hebbian-like plasticity. Linear network models reveal that these temporal dependencies between signal and noise correlations emerge only when Hebbian learning balances stochastic synaptic changes, preventing functional degradation. Our findings highlight how ongoing input-driven plasticity stabilizes neural representations amidst inherent synaptic variability. *About VVTNS : Launched as the World Wide Theoretical Neuroscience Seminar (WWTNS) in November 2020 and renamed in homage to Carl van Vreeswijk in Memoriam (April 20, 2022), Speakers have the occasion to talk about theoretical aspects of their work which cannot be discussed in a setting where the majority of the audience consists of experimentalists.

[Workshop in Mallorca] Embracing Complexity
by RUBÉN HERZOG 14 Feb '25

14 Feb '25

We are pleased to invite you to the Workshop titled "Embracing Complexity: Principled and Practical Approaches to Emergence". The workshop is scheduled for June 23-27 2025 at the Institute for Cross-Disciplinary Physics and Complex Systems (IFISC in Spanish) in Palma de Mallorca, Spain ( https://ifisc.uib-csic.es/en/) ABOUT THE WORKSHOP This workshop will offer a comprehensive and interdisciplinary perspective on the applications of emergence in examining various real-world systems, including its use in understanding high-order interactions and complexity across diverse biological and ecological scales. With an emphasis on the micro-to-macro relations between cells, humans, and ecology, we aim to present emergence both as a practical tool and a principled approach. The mornings will be devoted to theory-driven presentations that draw from recent operational advances in capturing emergent phenomena, while the afternoons will feature hands-on sessions tailored for practical implementation of these topics. Something we are most thrilled about will be a coordinated outdoor excursion during the week to unwind and visit the island. This is not all, we also plan to have an immersive installation centred on exploring a collective experience of emergence with the voluntary participation of all the attendees. We hope you will also be pleased to join! REGISTRATION All applications should submit an abstract, which will be the key element for selection. After selection, participants will be asked to pay a fee of 400€, which will cover 5 nights (from the 22nd to the 26th of June) at the residency of the Universidad de las Islas Baleares, breakfast, lunch, coffee breaks and the excursion. SUBMISSION DEADLINE 14 of March of 2025. Selection will be informed by the end of April of 2025. Abstract submission here <https://forms.gle/eQhWYyC3mjd6EhYC9>.

[image: VVTNS.png] https://www.wwtns.online <https://streaklinks.com/A9c7PbbpKY7PxB6PaAJWGD3-/https%3A%2F%2Fwww.wwtns.on…> - on twitter: wwtns@TheoreticalWide You are cordially invited to the lecture given by Lea Duncker Stanford on the topic of Evaluating dynamical systems hypotheses for pattern generation in motor cortex The lecture will be held on zoom on Wednesday, February 12, 2025, at *11:00 am EST * To receive the link: https://www.wwtns.online/register-page *Abstract: * The rich repertoire of skilled mammalian behavior is the product of neural circuits that generate robust and flexible patterns of activity distributed across populations of neurons. Decades of associative studies have linked many behaviors to specific patterns of population activity, but association alone cannot reveal the dynamical mechanisms that shape those patterns. Are local neural circuits high-dimensional dynamical reservoirs able to generate arbitrary superpositions of patterns with appropriate excitation? Or might circuit dynamics be shaped in response to behavioral context so as to generate only the low-dimensional patterns needed for the task at hand? Here, we address these questions within the primate motor cortex by delivering optogenetic and electrical microstimulation perturbations during reaching behavior. We develop a novel analytic approach that relates measured activity to theoretically tractable, dynamical models of excitatory and inhibitory neurons. Our computational modeling framework allows us to quantitatively evaluate different hypotheses about the dynamical mechanisms underlying pattern generation against perturbation responses. Our results demonstrate that motor cortical activity during reaching is shaped by a self-contained, low-dimensional dynamical system. The subspace containing task-relevant dynamics proves to be oriented so as to be robust to strong non-normal amplification within cortical circuits. This task dynamics space exhibits a privileged causal relationship with behavior, in that stimulation in motor cortex perturbs reach kinematics only to the extent that it alters neural states within this subspace. Our results resolve long-standing questions about the dynamical structure of cortical activity associated with movement, and illuminate the dynamical perturbation experiments needed to understand how neural circuits throughout the brain generate complex behavior. *About VVTNS : Launched as the World Wide Theoretical Neuroscience Seminar (WWTNS) in November 2020 and renamed in homage to Carl van Vreeswijk in Memoriam (April 20, 2022), Speakers have the occasion to talk about theoretical aspects of their work which cannot be discussed in a setting where the majority of the audience consists of experimentalists.
