Dear colleagues, *June 1-5 2015* will see the second *Model-based Neuroscience Summer School*, hosted at the *University of Amsterdam*. The school will provide students with hands-on experience in both cognitive modeling using diffusion and accumulator models and simple neuroscience methods. In addition, the program includes a debate between the two most prominent perspectives on the model-based neuroscience of perceptual decision-making. These perspectives place a different primary focus on either behavior (Ratcliff) or neural dynamics (Logan). Consequently, they bring different insights to the combined research agenda. The summer school is aimed at PhD students and early PostDocs who wish to combine cognitive modelling with experimental and theoretical neuroscience research. Students should be familiar with general programming concepts and state in their application which programming languages and software packages they typically use. The summer school is only 100 euro, however, we ask that students make their own housing arrangements. Space is limited, therefore we ask that you provide a statement of interest. We will base selection of students based on the relevance of the summer school to their research. More information about the teachers, preliminary programme, and application can be found at www.modelbasedneuroscience.com <http://www.modelbasedneuroscience.com/> We are looking forward to welcoming you in Amsterdam!
