This course is organized by the Translational Neuromodeling Unit (TNU) , University of Zurich & ETH Zurich and is designed to provide students across fields (neuroscience, psychiatry, physics, biology, psychology....) with the necessary toolkit to master challenges in computational psychiatry research.
The CPC Zurich is meant to be practically useful for students at all levels (MDs, Master, PhD, Postdoc, PI) coming from diverse backgrounds (neuroscience, psychology, medicine, engineering, physics, etc.), who would like to apply modeling techniques to study learning, decision-making or brain physiology in patients with psychiatric disorders. The course will teach not only the theory of computational modeling, but also demonstrate software in application to example data sets.
We strongly believe in open source and open science, therefore, the content of the course will be made freely accessible on the web.
Due to the current situation caused by the COVID-19 pandemic, the CPC will be held fully online (between 8am MESZ and 6pm MESZ):
• There will be NO registration fee.
• There will be additional means to interact with each other virtually.
• Number of places might be limited depending on the capacity of our technical setup. Students from the host institutions (UZH & ETH Zurich) will be prioritized.
• Number of places for each practical tutorial sessions are limited to 20 places
Please register for the main course and the tutorials via the registration form below:

Master Students, PhDs, PostDocs, Clinicians and anyone interested in Computational Psychiatry
3 ECTS for University of Zurich & ETH Zurich students
This course is part of the HS (fall term) 2020 and will be available on ETH MyStudies and the UZH course catalogue in due time. For ECTS you will need to sign up in ETH myStudies in addition to registering here. UZH students must register and sign up in ETH myStudies as “UZH Fachstudent/in”.
Short oral examination (date to be announced) at the TNU.
The CPC is divided into two parts: The main course (day 1-5) and in-depth practical tutorials (day 6).
The first day will cover topics in Psychiatry providing a conceptual basis for the type of questions that Computational Psychiatry will need to address.
The second day will explain basic modelling principles (basic mathematical terminology, step-by-step guide on how to build a model, model fitting, model inversion and model selection) and will finish with a first introduction to a possible learning model (Reinforcement Learning).
The third day will include models of perception (Psychophysics, Bayesian Models od Perception, Predicitve Coding) and action selection (Markov Decision Processes, Active Inference, Drift Diffusion Models).
The fourth day (only half a day) will include Machine Learning (basics and advanced) and models of connectivity (Dynamic Causal Modeling and Advanced Models of Connectivity).
The fifth day will feature a series of talks on practical applications of computational models to problems from psychiatry.
The sixth day of the course will provide in-depth practical sessions of a subset of the presented models for a smaller fraction of students (seperate registration).
The practical tutorials on the sixth day will provide 3-hour, small-group, in-depth and hands-on sessions on a specific modelling approach. To get the most out of the tutorial, students are advised to bring their own laptops along. The practical sessions cover only open-source software packages. The code can be found under the respective links below.
In this tutorial, we will recap the theory underlying the HGF (a Hierarchical Bayesian Inference Model) and introduce the model in an accessible way. We will then discuss practical issues when fitting computational models to behavioral data and go through code examples using the HGF Toolbox.
This tutorial provides a practical guide on developing computational models. You will be taught to build simple simulations using Matlab, and will use these to explore the behavioral and electrophysiological manifestations of active inference. We aim to develop an intuitive understanding of the theoretical principles, without requiring detailed technical knowledge.
In this tutorial, you will learn how to use a Bayesian package called hBayesDM for modeling various reinforcement learning and decision making (RLDM) tasks. A short overview of (hierarchical) Bayesian modeling will also be provided. You will also learn the most important things you need to check when reporting modeling results in publications.
This hands-on tutorial is a crash course on practical computational modelling. You will build a simple model (delay discounting) and learn how to apply it on empirical data to perform parameter estimation and model selection. We will use the VBA-toolbox which contains all the tools to simulate, estimate, and diagnose your models, as well as a collection of ready-to-use models (e.g. Q-learning, DCM). No previous experience with modelling is required, but basic knowledge of Matlab is recommended.
Would you like to learn more about normative modelling in psychiatry? In this tutorial you will learn the “why” and the “how” of simple normative models. You will take home a better understanding of this technique, machine learning, and some transferable Python programming skills.
In this tutorial you will learn how to use the SPM software to perform a dynamic causal modeling (DCM) analysis in Matlab. We will first guide you through all steps of a basic DCM analysis of a single subject: Data extraction, Model setup, Model inversion and, finally, inspection of results. We will then proceed to look at a group of subjects. Here, we will focus on model comparison and inspection of model parameters. We will provide a point-by-point recipe on how to perform the analysis. However, it is of advantage if you have worked with neuroimaging (fMRI) data and Matlab before.
Regression dynamic causal modeling (rDCM) represents a novel variant of DCM for fMRI that allows inferring effective (directed) connectivity in whole-brain networks with high computational efficiency. In this tutorial, you will familiarize yourself with the rDCM toolbox, get insights into the theoretical concepts and practical applications of the model, and learn how to set-up your own whole-brain effective connectivity analyses. Experience with (standard) DCM and Matlab programming is beneficial for this tutorial.
In this tutorial, you will learn how to use the HUGE-toolbox to perform model-based group-level analysis on task fMRI data. HUGE is a hierarchical extension of dynamic causal model (DCM) for fMRI which provides a unified framework for performing fitting of DCM and group-level analysis, such as empirical Bayesian analysis or stratification, i.e. the identification of subgroups, of heterogeneous cohorts. For this tutorial, we expect that you have experience with classical fMRI analysis and classical DCM, and a basic level of familiarity with the Matlab programming language.
