Designing neurophysiology experiments to optimally constrain receptive field models along parametric submanifolds
2008
Neural Information Processing Systems
Preserved Fulltext
Here we describe how to use stronger prior information, in the form of parametric models of the receptive field, in order to construct optimal stimuli and further improve the efficiency of our experiments ...
Sequential optimal design methods hold great promise for improving the efficiency of neurophysiology experiments. ...
In many experiments, neurophysiologists expect a-priori that the receptive field of a neuron will have some low-dimensional parametric structure; e.g the receptive field might be well-approximated by a ...

In particular, several relationships between the cortical morphologies and the parametric dependencies of extracted features are formalized and considered from a harmonic analysis point of view. ...
This can be interpreted as a principle of dimensionality reduction constrained to optimally independent representation of orientations, in the following sense. ...
The purpose of this paper is to review some key facts about mathematical models of neurophysiological behaviors, to show some new properties of these models, to present some open problems that can be of ...
