<h2>Aims and topics</h2>
Methods originally developed in Information Theory have found wide applicability in computational neuroscience. Beyond these original methods there is a need to develop novel tools and approaches that are driven by problems arising in neuroscience.<br>
A number of researchers in computational/systems neuroscience and in information/communication theory are investigating problems of information representation and processing. While the goals are often the same, these researchers bring different perspectives and points of view to a common set of neuroscience problems. Often they participate in different fora and their interaction is limited.<br>
The goal of the workshop is to bring some of these researchers together to discuss challenges posed by neuroscience and to exchange ideas and present their latest work.<br>
The workshop is targeted towards computational and systems neuroscientists with interest in methods of information theory as well as information/communication theorists with interest in neuroscience.<br>
For the program of the past IT workshops see the <a href="#prev">Previous workshops</a> section.

<!-- <b>Rodrigo Corfe Torres</b> - <i>"High-Order Interdependencies in the Aging Brain"</i><br/> -->
<!-- Brain interdependencies can be studied from either a structural/anatomical perspective ("structural connectivity") or by considering statistical interdependencies ("functional connectivity", FC). While structural connectivity is by definition pairwise (white-matter fibers project from one region to another), FC is not. However, most FC analyses only focus on pairwise statistics and they neglect higher order interdependencies. A promising tool to study high-order interdependencies is the recently proposed O-Information, which can quantify the intrinsic statistical synergy and the redundancy in groups of three or more interacting variables. In this talk, I will present the analysis of functional magnetic resonance imaging (fMRI) data obtained at rest from 164 healthy subjects with ages ranging in 10 to 80 years using the O-Information to investigate how high-order statistical interdependencies are affected by age. We showed that older participants (from 60 to 80 years old) exhibited a higher predominance of redundant dependencies compared with younger participants, an effect that seems to be pervasive as it is evident for all orders of interaction. In addition, while there is strong heterogeneity across brain regions, we found a "redundancy core" constituted by the prefrontal and motor cortices in which redundancy was evident at all the interaction orders studied.<br/> -->

<!-- Aiming to understand the functioning of the human brain in non-ordinary states of consciousness, we developed tools to assess brain connectivity using complex networks and information theory approaches. As a result, we observed that some aspects of the functional brain networks of individuals under psychedelic influences exhibit higher entropy and high information parity. -->

<!-- <b>Aaron Gutknecht</b> - <i>"Bits and Pieces: Understanding Information Decomposition from Part-Whole Relationships"</i><br/> -->
<!-- Partial Information Decomposition (PID) seeks to decompose the information that a set of source variables contains about a target variable into basic pieces, the so called "atoms of information". It not only promises to provide a complete description of the informational relationships between source and target variables but may also be conceived of as a unifying framework for systematically testing and comparing theories about neuronal processing in terms of their information theoretic predictions. This talk describes how the entire theory of partial information decomposition can be derived from considerations of elementary parthood relationships between information contributions. The underlying idea is that any theory should be grounded in as simple concepts as possible. Being one of the most basic relationships in nature, the part-whole relation is a prime candidate for such a foundational concept. It appears on all spatial and temporal scales, and is ubiquitous not only in science but also in ordinary life. Starting from this vantage point may therefore provide a particularly accessible exposition of partial information decomposition and it helps answering a range of questions that have been much discussed in the PID-field. The talk does not assume any previous familiarity with the PID-framework as we will re-derive the theory from first principles. -->

<!-- <b>Lucas Rudelt</b> - <i>"Embedding optimization reveals long-lasting history dependence in neural spiking activity"</i><br/> -->
<!-- Information processing can leave distinct footprints on the statistics of neural spiking. For example, efficient coding minimizes the statistical dependencies on the spiking history, while temporal integration of information may require the maintenance of information over different timescales. To investigate these footprints, I will present an approach that quantifies history dependence within the spiking of a single neuron, using the mutual information between the entire past and current spiking. On different neuron models, I will demonstrate that this approach captures a footprint of information processing that is beyond classical time-lagged measures of temporal dependence like the autocorrelation. I will then explain the practical challenges of estimating the mutual information, in particular when quantifying temporal dependencies. For experimental data, which are necessarily of limited size, a reliable estimation is only possible for a coarse temporal binning of past spiking, a so-called past embedding. To still account for the vastly different spiking statistics and potentially long dependencies of living neurons, I will introduce a novel approach to optimize the past embedding. Finally, I will show results on extra-cellular spike recordings, where we found that the strength and the timescale of history dependence showed striking differences between different neural systems. This work introduces a toolkit for the estimation of history dependence in recorded spike trains, which could provide valuable insights on how information processing is organized in the brain. -->

<!-- Behavior involves the ongoing interaction between an organism and its environment. One of the prevailing theories of adaptive behavior is that organisms are constantly making predictions about their future environmental stimuli. However, how they acquire that predictive information is still poorly understood. Two complementary mechanisms have been proposed: predictions are generated from an agent’s internal model of the world or predictions are extracted directly from the environmental stimulus. In this work, we demonstrate that predictive information, measured using bivariate mutual information, cannot distinguish between these two kinds of systems. Furthermore, we show that predictive information cannot distinguish between organisms that are adapted to their environments and random dynamical systems exposed to the same environment. To understand the role of predictive information in adaptive behavior, we need to be able to identify where it is generated. To do this, we decompose information transfer across the different components of the organism-environment system and track the flow of information in the system over time. To validate the proposed framework, we examined it on a set of computational models of idealized agent-environment systems. Analysis of the systems revealed three key insights. First, predictive information, when sourced from the environment, can be reflected in any agent irrespective of its ability to perform a task. Second, predictive information, when sourced from the nervous system, requires special dynamics acquired during the process of adapting to the environment. Third, the magnitude of predictive information in a system can be different for the same task if the environmental structure changes. These results indicate that decomposing multivariate information and measuring these quantities in time is not simply powerful but also necessary to understand neural network operation. -->

<!-- The brain is often described as “processing” information. Practically, however, “information processing” is often vaguely defined, making an exact model connecting neural dynamics, “computation”, and behavior difficult to pin down. Much of the previous empirical work on this topic has been done in systems or models that do not display complex behavior (e.g. in-vitro cultures, or anesthetized animals), leaving the relationship with complex behavior unclear. Here, we describe work done on cortical spiking activity recorded from three macaques engaged in multiple complex behaviors, including: symbolic recognition, active memory maintenance, and instructed motor action. We report a full complement of information dynamics phenomena, including active information storage, multivariate transfer entropy, as well as redundant and synergistic processing and find robust differences between them across different behavioral states. By making use of the inferred multivariate transfer entropy network, we can also assess how information processing in the system as a whole changes with a high degree of specificity (e.g. global network structure discriminates between the specific contents of memory being maintained, such as different instructed, but not executed, motor behaviors). Finally we show that the effective connectivity network approach and the information-dynamic approach intersect: the structure of the local neighborhood of a given neuron (such as local clustering coefficient) informs on the particular kinds of information dynamic it participates in (such as synergistic processing). This suggests a deeper relationship between network structure and function that combines elements of topology with distributed computation. -->

<!-- <b>Shuai Shao</b> - <i>"Efficient neuronal coding of static stimuli with different noise types and different objective functions"</i><br/> -->
<!-- In the view of evolution, neurons should be optimally configured to encode information most efficiently. This is the main statement of the efficient coding theory. Here we analyze the efficient neuronal coding problem with different noise types: input noise, which comes from the uncertainty of external stimuli, and output noise, which is due to intrinsic spike statistics of neurons. We generalize previous work limited to binary neurons and Poisson spiking noise (Gjorgjieva et al. PLOS CB 2019) to any shape of tuning curves and any forms of spiking noise. We also investigate different objective functions, the Shannon mutual information and mean square estimation error, to tackle different noise types and investigate how coding depends on the optimality measure. Finally, we show that the two objective functions are almost proportional to each other in some circumstances, which suggests that the choice of objective function might not be a critical element in efficient neuronal coding problems. -->

<!-- <b>Jake Witter</b> - <i>"A Nearest-Neighbours Estimator for Conditional Mutual Information"</i><br/> -->
<!-- The conditional mutual information quantifies the conditional dependence of two random variables. It has numerous applications; it forms, for example, part of the definition of transfer entropy, a common measure of the causal relationship between time series and important to neuroscience. It does, however, require a lot of data to estimate accurately, much more than is typically available from a neuroscience experiment, and suffers the curse of dimensionality - limiting its application in machine learning and data science. We have used a Kozachenko-Leonenko approximation to derive a nearest-neighbours estimator. This estimator depends only on the distance between data points, something somewhat understood for neural recordings, and not on the dimension of the data; furthermore, for this estimator it is possible to calculate the bias analytically. -->
