Role of Single Low Pulse Intensity of Transcranial Magnetic Stimulation Over the Frontal Cortex for Cognitive Function
2020
Background: The principal aim of this study was to measure the effect of online single-pulse transcranial magnetic stimulation (TMS) over the right dorsolateral prefrontal cortex (DLPFC) on cognition via the Cambridge Neuropsychological Test Automated Battery (CANTAB) in healthy individuals. Methods: In a single-blind, sham-controlled study, we assessed both 50% and 60% of the resting motor threshold (RMT) over the right DLPFC in healthy right-handed (n = 42) adults using cognitive function, such as attention and memory, as a measure via CANTAB. Results: We observed an improvement in the cognitive function level during the use of online low intensities of 50% and 60% RMT active stimulation …
Interhemispheric inhibition during mental actions of different complexity.
2013
International audience; Several investigations suggest that actual and mental actions trigger similar neural substrates. Yet, neurophysiological evidences on the nature of interhemispheric interactions during mental movements are still meagre. Here, we asked whether the content of mental images, investigated by task complexity, is finely represented in the inhibitory interactions between the two primary motor cortices (M1s). Subjects' left M1 was stimulated by means of transcranial magnetic stimulation (TMS) while they were performing actual or mental movements of increasing complexity with their right hand and exerting a maximum isometric force with their left thumb and index. Thus, we sim…
The Role of the Amygdala in the Extinction of Conditioned Fear
2006
The amygdala has long been known to play a central role in the acquisition and expression of fear. More recently, convergent evidence has implicated the amygdala in the extinction of fear as well. In rodents, some of this evidence comes from the infusion of drugs directly into the amygdala and, in particular, into the basolateral complex of the amygdala, during or after extinction learning. In vivo electrophysiology has identified cellular correlates of extinction learning and memory in the lateral nucleus of that structure. Human imaging experiments also indicate that amygdaloid activity correlates with extinction training. In addition, some studies have directly identified changes in mole…
Enhancing memory performance with rTMS in healthy subjects and individuals with Mild Cognitive Impairment: the role of the right dorsolateral prefron…
2012
A debated question in the literature is the degree of anatomical and functional lateralization of the executive control processes subserved by the dorsolateral prefrontal cortex (DLPFC) during recognition memory retrieval. We investigated if transient inhibition and excitation of the left and right DLPFC at retrieval by means of repetitive transcranial magnetic stimulation (rTMS) modulate recognition memory performance in 100 healthy controls (HCs) and in 8 patients with Mild Cognitive Impairment (MCI). Recognition memory tasks of faces, buildings and words were used in different experiments. rTMS-inhibition of the right DLPFC enhanced recognition memory of verbal and non verbal material in…
Hemispheric Differences in Functional Interactions Between the Dorsal Lateral Prefrontal Cortex and Ipsilateral Motor Cortex
2020
Background: The dorsolateral prefrontal cortex (DLPFC) in both hemispheres have a central integrative function for motor control and behavior. Understanding the hemispheric difference between DLPFC and ipsilateral motor cortex connection in the resting-state will provide fundamental knowledge to explain the different roles DLPFC plays in motor behavior. Purpose: The current study tested the interactions between the ipsilateral DLPFC and the primary motor cortex (M1) in each hemisphere at rest. We hypothesized that left DLPFC has a greater inhibitory effect on the ipsilateral M1 compared to the right DLPFC. Methods: Fourteen right-handed subjects were tested in a dual-coil paired-pulse parad…
Different ways to organize the processes of financial administration : a field study of medium-sized Finnish companies
2011
This research concentrates on exploring the ways how financial administration is currently organized in medium-sized companies in Finland. Decentralization, centralization and outsourcing are options that are available to different-sized companies. The study was executed as a field study in seven medium-sized Finnish companies that represent different branches. Furthermore, the research method was qualitative theme interview. As large companies have already established their financial service centers and small enterprises have outsourced their financial administration to bookkeeping agencies, medium-sized companies are located between the two, finding a way that is suitable for their strate…
La calidad en la gestión de los Servicios Sociales Municipales: algunas experiencias de INTRESS
2011
Queremos presentar en este breve artículo dos experiencias de INTRESS en el desarrollo de buenas prácticas que puedan ayudar a la implantación de sistemas de gestión de calidad en las administraciones locales así como en organizaciones y entidades del Tercer Sector. Se expone pues, por un lado, la experiencia desarrollada en la Concejalía de Acción Social, Mujer y Familia del Ayuntamiento de Valdemoro (Madrid) a través de la formación de sus profesionales en la gestión por procesos y la mejora continua y por otro lado, la iniciativa 'Indicadores Sociales' desarrollada por la red de Consultoría Social, para el desarrollo de una Web de indicadores sociales que permita compartir resultados y b…

Self-regulation of learning: the potential technologies impact of the metacognitive approach
2012
Self-regulation researchers theorize that self-regulation does not occur when learners display personal initiative, perseverance, and adaptive skill in pursuing learning. At its core, self-regulation involves self-motivation as well as metacognitive processes. Reflection on the process of learning is believed to be an essential ingredient in the development of expert teachers. By employing reflective thinking skills to evaluate the results of one’s own learning efforts, awareness of effective learning strategies can be increased and ways to use these strategies in other learning situations can be understood. In this paper, we describe how expert teachers use the knowledge they have gained o…
Pleasant Musical Imagery : Eliciting Cherished Music in the Second Person
2019
This article introduces the notion of pleasant musical imagery (PMI) for denoting everyday phenomena where people want to cherish music ‘‘in their heads.’’ This account differs from current paradigms for studying musical imagery in that it is not based a priori on (in)voluntariness of the experience. An empirical investigation of the structure and experiential content in 50 persons’ experiences of PMI applied the elicitation interview method. Peer judgments of the interviews helped to bridge a phenomenological investigation of particular experiences with systematic between-subjects analysis. Both structural features of the imagery (e.g., Looseness of structure or Looping) and content featur…
