Date of Defense 2011-03-24 Availability unrestricted Abstract In this thesis we investigate statistical modelling of neural activity in the brain. We rstdevelop a framework which is an extension of the state-space Generalized Linear Model
(GLM) by Eden and colleagues [20] to include the eects of hidden states. These states,
collectively, represent variables which are not observed (or even observable) in the modelling
process but nonetheless can have an impact on the neural activity. We then develop a
framework that allows us to input apriori target information into the model. We examine
both of these modelling frameworks on motor cortex data recorded from monkeys performing
dierent target-driven hand and arm movement tasks. Finally, we perform temporal coding
analysis of sensory stimulation using principled statistical models and show the ecacy of
our approach.
