This article employs a simple model of sophisticated voting under incomplete information and explores the strategic contexts of the vote on political reform bills in Japan. The government-sponsored political reform bills were voted down by the defection of government coalition members in the House of Councillors before a final compromise was reached in the joint committee of both houses and passed subsequently. In contrast to the accepted view that the defectors were short-sighted sincere voters, I show that Japan's institutional arrangements (...) created an uncertainty about the agenda in the legislative process and led to the sophisticated voting behavior of pivotal voters whose preferences were different from the party leadership. The analysis underscores the importance of sophisticated voting for the empirical study of Japanese legislative politics. (shrink)

Recent advanced statistical analysis of complex spikes has revealed that their instantaneous firing rate within a time bin of a few milliseconds carries information if many trials are averaged, as happens in motor learning. The firing rate encodes sensory error signals in the inverse-dynamics motor-command coordinates, and these are exactly the same coordinates as for simple spikes. This strongly supports the most critical assumption of the feedback-error-learning model and argues against several hypotheses about the functions of the complex spikes.
