Stability and change in the hippocampal place representation system
More information שעה כל היוםמיקום אולם הרצאות ע"ש גרהרד שמידטמרצה Prof. Dori Derdikman מארגן המחלקה למדעי המוחצרו קשר תקציר Show full text abstract about Memory formation and maintenance involve a constant tension ...» Memory formation and maintenance involve a constant tension between stability andchange. On one hand, stable representations are essential for preserving past experiences.On the other hand, memories must remain flexible to incorporate new information andreflect the evolving world. Thus, while memory resists interference to maintain invariance, itmust also reorganize to enhance efficiency and adapt to novel experiences.In this lecture, I will discuss one to three studies examining this balance within thehippocampal spatial representation system. First, regarding representational drift, spatialrepresentations in the hippocampus gradually change with experience. Our findings suggestthat such changes are driven more by ongoing experience than by forgetting. Second, inexploring environmental mapping, we find that the subiculum encodes differently shapedrooms with strikingly similar activity patterns, hinting at an invariant, latent representation ofspatial structure. Third, we investigate a flashbulb memory–like effect, observingpronounced hippocampal activity changes following salient life events in mice.Together, these projects illustrate how the hippocampus negotiates the trade-off betweenpreserving established memories and accommodating new experiences. -

This perspective aligns with how we model real world attackers and can enable outcomes that are provably impossible against unbounded adversaries. Although this idea has long been a driving force in cryptography and complexity theory, it has not been fully exploited in several natural and fundamental problems that have traditionally been studied in the unbounded adversary model.
In this talk, we show that adopting this computational perspective enables us to surpass information theoretic limits in three classic settings: communication, randomness, and privacy.
Communication: We construct efficient error correcting codes for computationally bounded adversaries that achieve information rates provably higher than those possible against unbounded adversaries.
Randomness: While seedless deterministic extraction is impossible for general sources, we show that it is possible to deterministically extract and condense randomness from low-entropy efficiently samplable sources.
Privacy: We consider two party differential privacy and show that achieving accuracy beyond information theoretic limits is tightly connected to cryptographic power, yielding a characterization of the computational assumptions that are necessary. -

As a structure periodic on the micron length scale, the cholesteric acts as a diffraction grating, affording a labradorescent splendor to the casual observer. While these discoveries were being made, Maxwell developed the theory of canal surfaces; surfaces swept out by a sphere of varying radius moving along an arbitrary path. I will use a new observation of cholesteric droplets to explain the connection between canal surfaces, focal conic domains, and Apollonian packing. The power of geometric thinking will be highlighted. -

After some background on the paradigm and techniques of circuit analysis, I'll present two (and a half) research studies demonstrating the breadth of these interpretability methods.
We will explore how this paradigm can help gain scientific insights into how neural network models operate, exemplified in the first work ("Arithmetic without Algorithms", https://technion-cs-nlp.github.io/llm-arithmetic-heuristics) where we use circuit analysis to reveal how language models solve arithmetic prompts. We will also show that circuit analysis can reveal findings on neural network models and help fix existing problems in them --- specifically targeting the issue of poor performance of VLMs on visual tasks compared to equivalent textual tasks (done in the work "Same Task, Different Circuits", https://technion-cs-nlp.github.io/vlm-circuits-analysis). Lastly, if time permits, we will discuss some current directions for future and ongoing work, mainly on scaling circuit analysis to complex tasks.

Yet despite major advances in generative AI, we are still far from models that can reason and communicate through visual forms.
I will present my work on bridging generative models and visual communication, focusing on three complementary domains: (1) algorithms for generating and understanding sketches, (2) systems that support exploratory visual creation beyond one-shot generation, and (3) methods for producing editable, parametric images for design applications.
These domains pose unique challenges: they are inherently data-scarce and rely on representations that go beyond pixel-based images commonly used in standard models. I will show how the rich priors of vision-language models can be leveraged to address these challenges through novel optimization objectives and regularization techniques that connect their learned features with the specialized representations required for visual communication.
Looking ahead, this research lays the foundation for general-purpose visual communication technologies: intelligent systems that collaborate with humans in visual domains, enhancing how we design, learn, and exchange knowledge.

It is pivotal in human communication, yet its structure and meaning remain subjects of ongoing research. I will describe a data-driven model for English prosody based on large-scale analysis of spontaneous conversations. As a first step, we identified approximately 200 discernible prosodic patterns, i.e., pitch contours typically spanning 1-4 words that we view as building blocks of a prosodic vocabulary, and outlined their properties and communicative meanings. Next, we revealed a Markovian logic, akin to a syntax, affecting how these elementary building blocks concatenate into coherent utterances. We further identified distinct compound functions associated with pairs of consecutive patterns and demonstrated that this Markovian structure is significantly more prevalent in spontaneous prosody compared to scripted speech. These findings offer insights into the underlying mechanisms of conversational prosody, empirically informing and refining existing theoretical concepts in linguistics. The methodology of combining unsupervised clustering analysis of large speech datasets with careful manual annotation could guide future research aimed at refining our model and expanding it to other languages. -

Lunch at 12:45צרו קשר תקציר Show full text abstract about Two major theories compete to explain the origin of aging. T...» Two major theories compete to explain the origin of aging. The first, proposed by Leo Szilard in 1959, attributes aging to DNA damage. The second, articulated by Robin Holliday in the 1980s, emphasizes epigenetic alterations. While both reveal plausible molecular origins of aging, they leave important puzzles unresolved. First, mutation and epimutation burdens increase linearly with age, whereas aging phenotypes exhibit strongly nonlinear behavior. Second, key aging phenotypes cannot be traced to specific genetic or epigenetic changes; instead, they emerge collectively from their cumulative effects on cellular function.In this talk, I will present a network resilience theory of aging that resolves these puzzles. Network resilience is formalized as the ability of a network to sustain its basic functions under changes in its topology and dynamical variables. Our theory conceptualizes aging as a progressive loss of network resilience as cells approach a novel critical mutation-epigenetic line. We identify two regimes of cellular stability, with young cells remaining resilient while older cells exhibit increased susceptibility. Using GTEx data and numerical simulations, we link transcriptional noise to cellular susceptibility and reproduce delayed immune activation observed in aging. Overall, our theory offers a novel perspective on aging based on resilience and critical phenomena. -

This seminar will highlight how supporting cells in the inner ear and myelinating glia in auditory and prefrontal circuits control circuit function. Our work in the inner ear shows how glia influence hearing, in particular the recently described “hidden hearing loss”, while our studies of juvenile social isolation demonstrate our early-life experience reshapes prefrontal myelination, neuronal function, and behavior through epigenetic mechanisms. Together, these findings point to glia‑mediated synaptic and myelin changes as key, complementary pathways through which development, experience, and aging impact circuit performance.
