New paper on cortical mechanisms of decision making:

Leendert van Maanen, Scott D. Brown, Tom Eichele, Eric-Jan Wagenmakers, Tiffany Ho, John Serences, Birte U. Forstmann (in press, J. Neuroscience) Neural correlates of trial-to-trial fluctuations in response caution.

This paper uses a cool new method developed by Leendert, Scott, EJ, and Birte to estimate parameters of a decision model (e.g. drift rate, response threshold, etc.) on a trial-by-trial basis, and then uses this approach to examine the neural mechanisms that mediate response caution.
