Corticostriatal Projection Neurons – Dichotomous Types and Dichotomous Functions
The mammalian striatum receives its main excitatory input from the two types of cortical pyramidal neurons of layer 5 of the cerebral cortex - those with only intratelencephalic connections (IT-type) and those sending their main axon to the brainstem via the pyramidal tract (PT-type). These two neurons types are present in layer 5 of all cortical regions, and thus they appear to project togethe...
متن کاملThe dichotomous history of diffusion
© 2009 American Institute of Physics, S-0031-9228-0907-030-6 Diffusion implies spreading, either observable (physical), or abstract and probabilistic (stochastic). At the beginning of the 19th century, the mathematics of both were established by Joseph Fourier and Pierre Simon Laplace. In 1807 Fourier submitted a monograph, Théorie de la propagation de la chaleur dans les solides (Theory of the...
متن کاملConsensus versus Dichotomous Voting
Consensus means general agreement among possibly di erent views, while dichotomus voting rules are a means of making decisions by using votes to settle di erences of view. How then can it often be the case that a committee whose only formal mechanism for decision-making is a dichotomus voting rule reaches a consensus? In this paper, based on a game-theoretic model developed in three previous pa...
متن کاملStructure in Dichotomous Preferences
Many hard computational social choice problems are known to become tractable when voters’ preferences belong to a restricted domain, such as those of singlepeaked or single-crossing preferences. However, to date, all algorithmic results of this type have been obtained for the setting where each voter’s preference list is a total order of candidates. The goal of this paper is to extend this line...
متن کاملQuaternary dichotomous voting rules
In this paper we provide a general model of quaternarydichotomous voting rules (QVRs), namely, voting rules for making collective dichotomous decisions (to accept or reject a proposal), based on vote pro les in which four options are available to each voter: voting (yes, noor abstaining) or staying home and not turning out. The model covers most of actual real-world dichotomus rules, wh...
