Brief Description

Including indirect pathway to counterbalance the direct pathway can effectively widen the range of threshold values, until GPe activity becomes largely suppressed.

Public:  YES

Decision threshold and its dependence on the strength of the indirect pathway.

"Decision threshold and its dependence on the strength of the indirect pathway. (AB) The distribution of decision times and thresholds for two motion-coherence levels. The decision time is modulated by coherence level of the stimulus (top), while the threshold is insensitive to the stimulus strength (bottom). (C) The dependence of threshold on the corticostriatal connection strength g(Cx-CD) for different values of g(CD-GPe), the strength of the indirect pathway. Error bars indicate SD."
