Several studies have found decision-making-related value signals in the dorsolateral prefrontal cortex (DLPFC). However, it is unknown whether the DLPFC plays a causal role in decision-making, or whether it implements computations that are correlated with valuations, but that do not participate in the valuation process itself. We addressed this question by(More)
We describe complementary iconic and symbolic representations for parsing the visual world. The iconic pixmap representation is operated on by an extensible set of “visual routines” (Ullman, 1984; Forbus et al., 2001). A symbolic representation, in terms of lines, ellipses, blobs, etc., is extracted from the iconic encoding, manipulated algebraically, and(More)
Tekkotsu (the name means “framework” in Japanese) is an application development framework for the Sony AIBO robot that endeavors to provide an intuitive set of primitives for perception, manipulation, and control. The framework also addresses some of the human-robot interaction problems faced by mobile robot application developers. See www.Tekkotsu.org. The(More)
Delivering transcranial magnetic stimulation (TMS) shortly after the end of a visual stimulus can cause a TMS-induced 'replay' or 'visual echo' of the visual percept. In the current study, we find an entrainment effect that after repeated elicitations of TMS-induced replay with the same visual stimulus, the replay can be induced by TMS alone, without the(More)
