CoSMo organization (Gunnar) – Day 1 30 min Introduction to sensory-motor control 1

The computational neuroanatomy of sensory-motor control (Gunnar) 20 min The anatomy of computation (Konrad) 30min

Link back to neuroanatomy – discuss different types of modelling (Marr etc + data analysis)

One computational way: Bayesian 100 min Sensory: cue combination (Konrad) Sensory-motor: decision making (Paul) Motor: Kalman filter & online control (Konrad)

Bayesian decoding PM tutorial (normative modelling & data analysis) How to model (Gunnar, Konrad & Paul) 5pm

Introduction to sensory-motor control 2

Rewind: orthogonal axes to first day (computational approach): systems in the brain (Konrad) 30min Many sensory-motor systems in the brain (Paul) 30min Eye movement example (Gunnar) 45min

Sensory processes underlying eye movements Sensory-motor for eye movements Eye motor control

Linear systems theory (John) 90min Saccade model PM tutorial (John) How to write papers (Konrad) 5pm
