Impulsivity: A view from the behavioral neuroscience and developmental psychology

Impulsivity has been linked to three main factors: performing without direct involvement of the frontal lobe functions, an increase in the speed of response, and the acquisition of immediate gratification. This behavioral inhibition deficit involves a variety of behaviors including aspects of hyperexcitability, behavioral disinhibition and higher order decision making. Although by tradition, the definition of this executive function has been conceptualized from a psychopathological view, currently, the wide variety of neuropsychological, developmental and animal models assessment techniques encourage us to establish dialogues that integrate the knowledge of these theoretical perspectives for the interpretation and understanding of impulsivity.

Consumer Neuroscience as a reserach issue, concepts and applications. A paradigmatic approach

Consumer neuroscience allows a fullest and objective understanding about desires andactions of consumers, turning itself in a fickle tool to the use of the companies and to improve their Marketing strategies. The use of the Neuroscientific methods to the analysis, description and comprehension of human behavior related to consume open a lot of unknown possibilities to discover. Neuromarketing or The consumer Neuroscience as is known too is the study of mental process been part of the consumer behavior and contexts concerning the marketing as well, apply and follow in the environment of the real life of human been. Its supported by the paradigms and the technological development of Neurosciences whose progress has made possible for the seekers to deep in knowledge abouthow the brain work. Physiological operations of mind are a product of a structural and functional ensemble including the brain, as organ, and mind, emotion and cognition, asfunctions. Mind events just can be understood in the middle of the interaction between the organism and his environment. Neuromarketing paradigm it’s still in his infancy and whatfor it’s full of research possibilities. Inside the consumer neuroscience the ethic building doesn’t collapse, the morality isn’t threaten, inside the normal individual Will it’s alwaysWill. The present paper looking for a place to the consumer neuroscience paradigm over the perspective of research open to the Marketing, from the technological advances and hermeneutical vision offer by Neuroscience; it’s propose some of several possibilities ofresearch and practice been explored actually. To give an example its offer one of methods of research as is the Evoked Potentials.

Equinoterapia en niños con autismo

Introducción: Autismo es un trastorno del desarrollo caracterizado por compromiso en interacción social, habilidades de lenguaje, presentando rituales con estereotipias. Sin tratamientos curativos, actualmente se buscan terapias alternativas. Un incremento de la literatura científica de terapias asistidas con animales se ha evidenciado, demostrando mejoría en pacientes autistas con la equinoterapia. Objetivo: Realizar una revisión sistemática de la literatura para evaluar efectividad de la equinoterapia en habilidades sociales y de lenguaje en niños autistas. Metodología: Revisión sistemática de la literatura de artículos obtenidos en bases de datos y Meta-buscadores que proporcionaron evidencia de equinoterapia en niños autistas. Tipo de artículos consultados: revisiones sistemáticas, meta análisis y ensayos clínicos. Trabajos publicados hasta 2013. En inglés y español. Se emplearon términos MeSH y EMTREE. Resultados: Cuatro artículos cumplieron criterios de inclusión y exclusión. Se analizaron los artículos individualmente, no se logró realizar un meta análisis por diferencias metodológicas entre los estudios. En total 85 sujetos fueron evaluados en dichos estudios. La equinoterapia en niños autistas evidenció mejoría en habilidades sociales y en las habilidades de lenguaje pre verbal. Discusión: La equinoterapia es prometedora en el manejo de niños autistas, los artículos evidencian consistentemente mejorías a nivel de habilidades sociales y de lenguaje. Debe ser considerado el tipo de paciente, el régimen de equinoterapia y la sostenibilidad de las mejoras. Conclusiones: Se necesitan nuevos estudio con un mayor rigor metodológico que permitan fortalecer la evidencia sobre la equinoterapia en niños con autismo y así poder realizar recomendaciones con un adecuado nivel de evidencia.

How neuroscience and sensorial theories can affect the marketing of different companies’ products and services?

El vertiginoso y competitivo panorama actual de los negocios, hace del mercadeo una herramienta muy importante para crecer o incluso sobrevivir. Hay muchas teorías alrededor de como vender un producto, servicio o idea, sin embargo la mayoría de estas consideran sólo las preferencias expresadas de forma consciente y las decisiones racionales. Este trabajo pretende hacer un acercamiento a las teorías de la neurociencia, como la sinergía entre los sentidos del ser humano y de como estas pueden nutrir el ámbito del mercadeo, por ello, se van a estudiar bibliografía relevante en torno a esta área para enmarcar el propósito del estudio. Después de la información obtenida a través de esta revisión, se analizaran dos importantes ejemplos de empresas mundialmente conocidas que han hecho uso de la neurociencia para el desarrollo de su mercadeo. Después de esto se concluye, a través de la información estudiada y analizada, cómo la neurociencia y las teorías multisensoriales pueden afectar el mercadeo de los diferentes productos y servicios. Este documento pretende vislumbrar efectos del mercadeo sobre las preferencias que nuestros cerebros muestran a través de la neurociencia, incluso si no sabemos sobre ellas.

A cell by cell anisotropic adaptive mesh ALE scheme for the numerical solution of the Euler equations

In this paper a cell by cell anisotropic adaptive mesh technique is added to an existing staggered mesh Lagrange plus remap finite element ALE code for the solution of the Euler equations. The quadrilateral finite elements may be subdivided isotropically or anisotropically and a hierarchical data structure is employed. An efficient computational method is proposed, which only solves on the finest level of resolution that exists for each part of the domain with disjoint or hanging nodes being used at resolution transitions. The Lagrangian, equipotential mesh relaxation and advection (solution remapping) steps are generalised so that they may be applied on the dynamic mesh. It is shown that for a radial Sod problem and a two-dimensional Riemann problem the anisotropic adaptive mesh method runs over eight times faster.

A cell by cell anisotropic adaptive mesh ALE method

A cell by cell anisotropic adaptive mesh Arbitrary Lagrangian Eulerian (ALE) method for the solution of the Euler equations is described. An efficient approach to equipotential mesh relaxation on anisotropically refined meshes is developed. Results for two test problems are presented.

Voronoi, Delaunay, and Block-Structured Mesh Refinement for Solution of the Shallow-Water Equations on the Sphere

Alternative meshes of the sphere and adaptive mesh refinement could be immensely beneficial for weather and climate forecasts, but it is not clear how mesh refinement should be achieved. A finite-volume model that solves the shallow-water equations on any mesh of the surface of the sphere is presented. The accuracy and cost effectiveness of four quasi-uniform meshes of the sphere are compared: a cubed sphere, reduced latitude–longitude, hexagonal–icosahedral, and triangular–icosahedral. On some standard shallow-water tests, the hexagonal–icosahedral mesh performs best and the reduced latitude–longitude mesh performs well only when the flow is aligned with the mesh. The inclusion of a refined mesh over a disc-shaped region is achieved using either gradual Delaunay, gradual Voronoi, or abrupt 2:1 block-structured refinement. These refined regions can actually degrade global accuracy, presumably because of changes in wave dispersion where the mesh is highly nonuniform. However, using gradual refinement to resolve a mountain in an otherwise coarse mesh can improve accuracy for the same cost. The model prognostic variables are height and momentum collocated at cell centers, and (to remove grid-scale oscillations of the A grid) the mass flux between cells is advanced from the old momentum using the momentum equation. Quadratic and upwind biased cubic differencing methods are used as explicit corrections to a fast implicit solution that uses linear differencing.

Predicting mesh density for adaptive modelling of the global atmosphere

The shallow water equations are solved using a mesh of polygons on the sphere, which adapts infrequently to the predicted future solution. Infrequent mesh adaptation reduces the cost of adaptation and load-balancing and will thus allow for more accurate mapping on adaptation. We simulate the growth of a barotropically unstable jet adapting the mesh every 12 h. Using an adaptation criterion based largely on the gradient of the vorticity leads to a mesh with around 20 per cent of the cells of a uniform mesh that gives equivalent results. This is a similar proportion to previous studies of the same test case with mesh adaptation every 1–20 min. The prediction of the mesh density involves solving the shallow water equations on a coarse mesh in advance of the locally refined mesh in order to estimate where features requiring higher resolution will grow, decay or move to. The adaptation criterion consists of two parts: that resolved on the coarse mesh, and that which is not resolved and so is passively advected on the coarse mesh. This combination leads to a balance between resolving features controlled by the large-scale dynamics and maintaining fine-scale features.
