Abstract
Interval discrimination task is a classical experimental paradigm that is employed to study working memory and decision making and typically involves four phases. First the subject receives a stimulus, then holds it in the working memory, then makes a decision by comparing it with another stimulus, and finally acts on this decision, usually by pressing one of the two buttons corresponding to the binary decision. A neurocomputational algorithm using generic neural microcircuits with feedback is presented here that integrates the four computational stages into a single unified framework. The algorithm is tested using two-interval discrimination and delayed-match-to-sample experimental paradigms as benchmarks.
