Summary on Grant Application Form |

Attention is becoming well studied, but still poses a basic fundamental puzzle: how is attention computationally achieved by the brain? More specifically, how do object and spatial representations achieve their attended forms? When a face, or a stimulus at a given spatial position, for example, are attended, various regions in the brain show increased activity, as observed by PET or fMRI. We propose to use experimental data, together with the framework of engineering control theory (recently applied very successfully to motor control achieved by the brain), along with neural simulations and mathematical analyses, to answer this question. In particular we will analyze the mechanism by which attention acts in a multiplicative manner, as in responses of single cells in attended brain regions (such as orientation sensitivity). This will be explored through the simulation of learning object and spatial codes with the aid of acetylcholine. We will apply this answer to target recognition and to goal creation. Analysis will concomitantly be given, using mathematical tools of information geometry and neural field theory, to understand theoretically how attention is effective in information processing. These results will be then used to give more specific content to the control model of attention.
