The Influence of Schizotypal Traits on Active Display Recognition

Accurate recognition of changes in scene layout is necessary to function in everyday life. Self-motion sensitivity, comprised of efference copy and afferent signals, is employed to respond to these changes, however little is known about how these signals may influence active display recognition. Previous spatial perception experimentation has shown that individuals with high schizotypal traits perform differently than those with low schizotypal traits while estimating walked distance in non-visual walking and imagined walking tasks (Rohde & Yamamoto, 2013). It is postulated that this result could be attributed to a presumable dysfunction of efference copy associated with schizotypy. It was hypothesized that lack of efference copy may influence other spatial perception tasks involving self-motion. This study investigated the influence of efference copy on active display recognition by comparing accuracy scores of high and low schizotypal groups. Contrary to the prediction, results found no significant difference between groups in accuracy for detecting change in a scene, suggesting that tasks that rely exclusively on body-based information (e.g. non-visual perception of walked distance) may be more susceptible to dysfunction in efference copy, or simply that the degree of possible efference copy dysfunction in the current participants was not large enough. Information from this study can be used to shape continuing research to define the role of efference copy in spatial perceptio

Physical simulation of wind pressure on building models at various arrangement and airflow conditions

The results of modeling and distribution of the pressure coefficient on the faces of the faces of the model of a high-rise building with a relative height of H/a = 3 and 6 are obtained under the influence of vortex flows created by an obstacle with similar geometric parameters with its lateral displacement from the longitudinal axis of the channel. The accepted range of transverse displacements is L2/a = 0.5; 1; 1.5; 2. In the range of studies, the airflow angle of 0 degrees was adopted with the maximum Reynolds number (Re) = 4.25´104. The distances between the models in the wake correspond to the calibers L1/a = 1.5; 3 and 6. A series of experiments was carried out on the basis of the theory of modeling. The experiments are based on the modeling of the model buildings under study on the basis of the similarity theory. Systematic data are obtained on the distribution of the pressure coefficients Cp on the faces of the model, depending on its location in the track of the upstream model with a change in the distance between them in the transverse direction relative to the direction of the air flow

A phosphatidylinositol (4,5)-bisphosphate binding site within mu 2-adaptin regulates clathrin-mediated endocytosis

The clathrin adaptor complex AP-2 serves to coordinate clathrin-coated pit assembly with the sorting of transmembrane cargo proteins at the plasmalemma. Flow precisely AP-2 assembly and cargo protein recognition at sites of endocytosis are regulated has remained unclear, but recent evidence implicates phosphoinositides, in particular phosphatidylinositol (4,5)- bisphosphate (PI[4,5]P-2) in these processes. Here we have identified and functionally characterized a conserved binding site for PI(4,5)P2 within mu2-adaptin, the medium chain of the clathrin adaptor complex AP-2. Mutant p,2 lacking a cluster of conserved lysine residues fails to bind PI(4,5)P2 and to compete the recruitment of native clathrin/AP-2 to PI(4,5)P-2- containing liposomes or to presynaptic membranes. Moreover, we show that expression of mutant mu2 inhibits receptor-mediated endocytosis in living cells. We suggest that PI(4,5)P-2 binding to mu2-adaptin regulates clathrin-mediated endocytosis and thereby may contribute to structurally linking cargo recognition to coat formation
