… In this review, we examine the evidence that links neuronal selectivity for motion direction
to perceptual decisions. Parallels in the properties of DS mechanisms revealed by …

… Previous studies and models of perceptual decision making have … decision making, we
have asked human subjects to make perceptual decisions between multiple possible directions …

… noisy motion, perceptual decision task interleaved with our direction-category task to investigate
whether individual LIP neurons are selective for direction in the same way in both tasks. …

we stimulated direction-selective … preferred direction more often. Microstimulation quickened …

… The independent effects of microstimulation and the visual stimulus arise directly from their
differential influence on specific subpopulations of direction selective neurons. Our data do …

We trained monkeys to decide the direction of random-dot motion and indicate their decision …

… In this study we measured directional preferences for motor decisions between equivalent
alternatives and for ambiguous, bistable perceptual tasks. We found pronounced preferences …
