Performance in the cat's visual system: a behavioural and neurophysiological analysis.

Behavioural research, neurophysiological experiments and computer simulations are used in an attempt to analyze pattern recognition in the cat's visual system. The methods were chosen in such a way that the measurable performance data resulting from behavioural and neurophysiological experiments can be combined simply. It is shown that, with minor modifications, the methods can be adapted to every estimation and detection problem like pattern discrimination, movement detection and to the assessment of lesion effects, so that they are widely applicable. The system analysis permits the correct prediction of behavioural experiments and an approximate assignment of functions to the areas 17, 18 and 19 for the task set.
