Transcranial magnetic stimulation (TMS) studies have shown that cortico-cortical paired associative (ccPAS) can strengthen connectivity between the ventral premotor cortex (PMv) and primary motor (M1) by modulating convergent input over M1 via Hebbian spike-timing-dependent plasticity (STDP). However, whether ccPAS locally affects activity remains unclear. We tested 60 right-handed young healthy humans in two studies, using a combination of dual coil TMS left PMv to probe manipulate...
Two event-related brain potential (ERP) components, the frontocentral feedback-related negativity (FRN) and posterior P300, are key in feedback processing. The FRN typically exhibits greater amplitude response to negative unexpected outcomes, whereas P300 is generally more pronounced for positive outcomes. In an influential ERP study, Hajcak et al., (2005) manipulated outcome valence expectancy a guessing task. They found was larger outcomes regardless of expectancy, valence. These findings...
The objective was to evaluate the characteristics of exposure OP pesticides and health status in Chilean farm workers from Maule Region. An occupational questionnaire administered 207 agricultural non-agricultural workers. For group workers, we asked about specific history symptoms pesticide poisoning. main problem exposed previous poisoning (p < 0.001). Fifty-six percent reported consistent with acute use respiratory personal protective equipment younger age were against these symptoms,...
Humans tend to spontaneously imitate others' behavior, even when detrimental the task at hand. The action observation network (AON) is consistently recruited during imitative tasks. However, whether automatic imitation mediated by cortico-cortical projections from AON regions primary motor cortex (M1) remains speculative. Similarly, potentially dissociable role of AON-to-M1 pathways involving ventral premotor (PMv) or supplementary area (SMA) in unclear. Here, we used paired associative...
Abstract Background Agricultural workers are routinely exposed to pesticides, which associated with a range of adverse health outcomes, including potential impacts on mental such as depressive symptoms. In the Maule region Chile, an area characterized by intensive pesticide use, this study investigates association between exposure organophosphate (OP) pesticides and prevalence symptoms among agricultural workers. Methods We conducted longitudinal 78 participants, comprising occupationally...
La Escala Wechsler de Inteligencia para Niños — Quinta Edición es la más reciente actualización estas escalas. Esta nueva edición fue lanzada el año 2014 en Estados Unidos y presenta mejoras relevantes respecto versiones anteriores, como una estructura factorial actualizada que incluye un mayor número indicadores, nuevos puntajes proceso procedimientos construcción las normas. Estas son contexto nacional, puesto versión estaba previamente disponible Chile era WISC-IIIv.ch, cuya data del...
Introduction: The association of total arsenic exposure with impaired glucose tolerance and gestational diabetes has been shown; however, evidence regarding urinary inorganic in pregnant women is still limited. Our aim was to evaluate the between concentration among living Arica, Chile. Methods: Cross-sectional study receiving care at primary health centers urban Arica. concentration, while outcome. evaluated using multiple logistic regression models adjusted by age, education level,...
To evaluate organophosphate pesticide exposure and neuropsychological motor performance in agricultural non-agricultural workers the Maule Region Chile.Analytic cross-sectional study 93 exposed farm 84 unexposed workers. A battery of four tests was administered together with a neuro-motor physical examination.On Weschler adult intelligence scale (WAIS-IV), exhibited poorer than verbal comprehension (β=-3.2; p=0.034) processing speed (β=-4.4; p=0.036) full (β=-4; p=0.016), as well...
BACKGROUND: Environmental risk assessments and interventions to mitigate environmental risks are essential protect public health. While the objective measurement of hazards is important, it also critical address subjective perception health risks. A population’s a powerful driving force for action engagement in safety behaviors can inform development effective more sustainable policies. To date, no instruments available assess South America even though there many concerning issues region,...
To describe pesticide concentrations in distinct environmental matrices at two time points (low and high seasons local agricultural production) to estimate the association between presence of residues use pesticides home with sociodemographic variables schoolchildren Province Talca, Chile.A cross-sectional study was conducted 190 schoolchildren. Families were surveyed about their children's vegetable consumption school home, other variables. Additionally, we measured vegetables water...
