Spatial navigation and planning is assumed to involve a cognitive map for evaluating trajectories towards a goal. How such a map is realized in neuronal terms, however, remains elusive. Here we describe a simple and noise-robust neuronal implementation of a path finding algorithm in complex environments. We consider a neuronal map of the environment that supports a traveling wave spreading out ...

We used optical images acquired with the Wide Field Camera of Advanced for Surveys onboard Hubble Space Telescope and near-infrared data from GeMS/GSAOI to construct a high-resolution extinction map in direction bulge stellar system Liller 1. In spite its appearance globular cluster, 1 has been recently found harbor two populations remarkably different ages, it is second complex similar propert...

A goal-directed navigation model is proposed based on forward linear look-ahead probe of trajectories in a network of head direction cells, grid cells, place cells and prefrontal cortex (PFC) cells. The model allows selection of new goal-directed trajectories. In a novel environment, the virtual rat incrementally creates a map composed of place cells and PFC cells by random exploration. After e...

MYOCARDIAL ADAPTATION TO ISCHEMIA occurs through the activation of several tyrosine kinases (3). Phosphorylation of tyrosine kinases has been shown to be linked with the activation of both phospholipase C and phospholipase D, leading to the activation of multiple kinases including PKC and mitogen-activated protein (MAP) kinases. The MAP kinases play an essential role in mediating intracellular ...

We shall give a simple criterion for a given singular point on a surface to be a cuspidal cross cap. As an application, we show that the singularities of spacelike maximal surfaces in Lorentz-Minkowski 3-space generically consist of cuspidal edges, swallowtails and cuspidal cross caps. The same result holds for spacelike mean curvature one surfaces in de Sitter 3-space. Introduction Let U be a ...
