for correspondences – generally a computationally expensive task that becomes impractical for large set sizes. We present a new fast kernel function which maps unordered feature sets to multi-resolution histograms and computes a weighted histogram intersection in this space. This “pyramid match” computation is linear

The role of pannexin hemichannels in the anoxic

A theory about the possible functional roles of the bipartite dendrites of cortical pyramidal cells is presented that tries to fuse aspects of both Cardinal Cell Theory and Assembly Theory. The article treats resulting functional differences of both dendritic pathways in conjunction

Roles of IA and morphology in action potential propagation

propose that the brain's basic mechanism for discovering such complex regularities is implemented at the level of individual pyramidal cells in the cerebral cortex. The proposal has three essential components. (1) Pyramidal cells have 5-8 principal dendrites. Each such dendrite is a functional

In a minimal network model consisting of two pyramidal cells and one interneuron, we show how excitation and inhibition cooperate to produce "ring rate changes in pyramidal cells that are consistent with observed place cell "ring in region CA3 of the hippocampus. We show

mossy fiber to CA3 pyramidal cell synapse are monoquantal. J Neu-

Hippocampal CA1 pyramidal neurons have frequently been regarded as a homogeneous cell population in biophysical, pharmacological and modeling studies. Here we report robust differences between pyramidal neurons residing in the deep and superficial CA1 sublayers in the rat. Compared

Inhibitory synapses contacting the soma and axon initial segment are commonly presumed to participate in shaping the response properties of cortical pyramidal cells. Such an inhibitory mechanism has been explored in numerous computational models. However, the majority of inhibitory synapses target
