Arsenic is an environmental contaminant found in soil, water and air in some zones of the world. It has been widely studied for its effects as a human carcinogenic agent, but few studies have dealt with neurobehavioral effects. In addition, studies of arsenic effects on development have only addressed its effects on embryotoxicity and teratogenicity after a single oral, gavage or intraperitonea...

Our actions are constantly guided by decisions based on sensory information. The motor cortex is traditionally viewed as the final output stage in this process, merely executing motor responses based on these decisions. However, it is not clear if, beyond this role, the motor cortex itself impacts response selection. Here, we report activity fluctuations over motor cortex measured using MEG, wh...

This paper examines the alternation forms between 2nd person treatment —tú, usted, sumercé and vos— when it comes to address a single interlocutor in Bogotá, Colombia. Whilst case vaguely described literature is though quite frequent systematic Spanish of Bogotá. Based on oral data (fragments spontaneous conversations direct observations) plus information provided by both personal impression al...

Objectives: The aim of present study was to evaluate some effects of Crinum zeylanicum (C. zeylanicum) on central nervous system. Materials and Methods: C. zeylanicum methanolic bulb extract (250-1000 mg/kg orally), 2 mg chlorpromazine and 4 mg diazepam /kg body weight intraperitoneally respectively were tested in mice using Irwin test, pentobarbitone-induced sleep test, spontaneous motor acti...

Visual competition refers to the spontaneous change of the subjective perception of ambiguous visual patterns. We investigated how implicit and explicit auditory inputs affect the temporal characteristics of perceptual alternation and the interpretation bias in ambiguous visual patterns. Participants traced the perceived direction of apparent visual motion, while two task-irrelevant auditory to...

Rhotics, generally believed to be phonetically heterogeneous – are usually classified into one group of sounds due to their similar phonological behaviour and their diachronic and synchronic alternation [13, 12, 31, and 1]. Previous research has shown considerable segmental variation, especially in the realisation of /r/ in German which lead some authors to conclude that a positive description ...

In this article, we automatically create two large and richly annotated data sets for studying the English dative alternation. With an intrinsic and an extrinsic evaluation, we address the question of whether such data sets that are obtained and enriched automatically are suitable for linguistic research, even if they contain errors. The extrinsic evaluation consists of building logistic regres...
