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
