In this lecture, I will revisit the classical question of spine biophysics in the new age of connectomics, where nanometer-resolution electron microscopy allows us to reconstruct whole neurons with thousands of synapses and spines. I will show how spine density, spine-neck resistance, and the irregular geometry of individual spines can shape local synaptic signals, generate fast voltage dynamics, influence excitatory/inhibitory gating, and affect communication between neighboring spines. I will then discuss how automated reconstruction pipelines and biophysical modeling now make it possible to build digital neurons at spine and synapse resolution, and how AI-based approaches, such as our new AI-based TwinProp algorithm, allow us to ask - and get answer - to a fundamental question: what can a neuron compute? I will end by claiming that we now enter a new age of connectomics that provides an essential constraint on understanding how synapses, neurons, and circuits perform their computational functions. *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.

by Tatjana Tchumatchenko June 20, 2026

June 20, 2026

Dear friends and colleagues, I am looking to recruit international postdoctoral fellows to my lab. It would be great to attract scientists who didn't have yet exposure to the German neuroscience community and who would bring complementary expertise and perspectives. *Two postdoc positions (m/f/d) are available in the Tchumatchenko group.* The Tchumatchenko Group is seeking to attract two highly motivated postdoc candidates (0-5 years post PhD) to conduct research in the field of computational neuroscience. Prof. Tatjana Tchumatchenko was recently appointed a Henriette Herz scout at the Alexander von Humboldt foundation and is looking to attract two international postdocs though this funding scheme [1]. The ideal candidate will be an international, highly motivated, scientifically curious postdoctoral fellow with a strong work ethic and a PhD degree in life sciences, Neuroscience, Physics, Mathematics, Engineering or similar disciplines who looking to answer open question in computational neuroscience. Great social skills, excellent command of the English language and enthusiasm for working in a competitive interdisciplinary research team are essential. Potential scientific projects should lie either at the boundary between behavioral analysis and circuit neuroscience or at the boundary between molecular dynamics and circuit neuroscience: how is the molecular dynamics organized across the brain and what are statistical differences across cell types? How can we design computational models and conduct data analysis at the level transcriptomes and proteomes to understand the implementation of physiological and behavioral conditions across the brain? How can we relate learning at the level of synapses and circuits to behavioral changes observed in animals? Can we identify behavioral states and link them to particular circuit activity states? Please send your application together with a cover letter, a CV with contact details from one academic reference and copies of all relevant degree certificates to tatjana.tchumatchenko(a)uni-bonn.de.

Graduate student and postdoctoral positions available in the Active Perception Laboratory at UR
by Poletti, Martina June 15, 2026

June 15, 2026

Graduate student and postdoctoral positions are available in the Active Perception Laboratory (http://aplab.bcs.rochester.edu) at the University of Rochester to study the perceptual consequences of eye movements under the supervision of Dr. Martina Poletti and/or Dr. Michele Rucci. We are particularly interested in recruiting candidates interested in investigating the roles of eye movements in establishing spatial representations, the spatiotemporal dynamics of foveal and extrafoveal processing, the interplay between eye movements, retinal anatomy, and attention, and the possible roles of eye movements in emmetropization and myopia. Research in the laboratory focuses on the interaction between vision and behavior. Our work relies on the integration of theoretical and experimental approaches to investigate how visual functions unfold in the presence of normal and abnormal motor activity, how vision guides behavior, and how changes in visual input signals and modulations associated with behavior contribute to perception. The laboratory is equipped with a unique array of tools, many developed in-house, to investigate the synergy between visual, motor, and cognitive processes (https://aplab.bcs.rochester.edu/facilities.html#<https://aplab.bcs.rochester.edu/facilities.html>). Approaches include human psychophysics with precisely controlled retinal stimulation, computational modeling, precise measurements of head and eye movements, high-resolution retinal imaging, and electroencephalography (EEG) during active vision. A full list of our publications can be found at https://aplab.bcs.rochester.edu/publications.html. The ideal candidate would have a strong interest in vision science, a background in related areas, and experience with data analysis and computer programming. Prior experience in eye-tracking, psychophysics, computational modeling, signal processing, and/or electroencephalography is a plus. Motivation and independence are important, as well as the ability to work well in a team. The University of Rochester offers a highly collaborative and stimulating research environment with excellent opportunities for interactions and training in vision science and neuroscience. The laboratory is located within the Center for Visual Science (http://www.cvs.rochester.edu/) and the department of Brain & Cognitive Sciences (http://www.sas.rochester.edu/bcs/) Ongoing collaborations at the University of Rochester include the Flaum Eye Institute (https://www.urmc.rochester.edu/eye-institute.aspx) the Institute of Optics (http://www.hajim.rochester.edu/optics/) and the department of Neuroscience (https://www.urmc.rochester.edu/neuroscience.aspx) To apply, please send curriculum vitae, a statement of research interests and accomplishments, and the names of two references to Martina Poletti (martina_poletti(a)urmc.rochester.edu<mailto:martina_poletti@urmc.rochester.edu>) and Michele Rucci (mrucci(a)ur.rochester.edu<mailto:mrucci@ur.rochester.edu>). ------ Martina Poletti, PhD Associate Professor Department of Brain and Cognitive Sciences Department of Neuroscience Center for Visual Science University of Rochester Active Perception Laboratory web: https://www.sas.rochester.edu/bcs/people/faculty/poletti_martina/index.html aplab.bcs.rochester.edu<http://aplab.bcs.rochester.edu/>

Fwd: [seminar.wwtns] World wide VVTNS series (6th season): June 17 2026 | From microcircuits to cortex-wide networks: connectivity and information-flow underlying goal-directed behavior| Arseny Finkelstein, Tel Aviv University

In this talk, I will discuss how cortical circuits organize neural activity and connectivity across spatial scales, from local microcircuits to distributed cortex-wide networks. Using naturalistic multidirectional reaching in mice, combined with large-scale calcium imaging and causal connectivity mapping of >20,000,000 neuronal pairs, we identified connectivity motifs and population dynamics underlying goal-directed behavior. I will first describe the organizational principles of the motor cortex, where neurons are arranged into functional mini-columns with recurrent connectivity motifs linked to task-related activity, and discuss the potential computational advantages of this architecture. I will then show how these principles extend to larger spatial scales. Imaging ~1,000,000 neurons across 10 cortical regions revealed high-dimensional local population activity patterns alongside coordinated cortex-wide dynamics mediated by synchronized inter-areal communication. These distributed network dynamics supported high-dimensional representations of short-term memory for target location. Together, these findings reveal how cortical networks are organized across spatial scales to support cognition. *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.
