          Stochastic representations in the nervous system


The brain is constantly making inferences about environmental variables 
in order to interpret stimuli and plan actions. In order to do so, it 
needs to maintain a model of the environment in which inferences on not 
directly observable quantities can be accomplished. We argue that the 
noisy and incomplete data received through the senses motivates a 
probabilistic representation. This approach enables us to build ideal 
observer models to establish optimal performance. We will discuss why 
sensory cortex cares little about what the senses communicate, how a 
noisy nervous system can be a design that seeks to achieve optimal 
performance, and why the processing pipeline is two-directional in a 
hierarchical model of the environment?
