Long-Term Potentiation in the Neonatal Rat Barrel Cortex In Vivo
2012
Long-term potentiation (LTP) is important for the activity-dependent formation of early cortical circuits. In the neonatal rodent barrel cortex, LTP has been studied only in vitro . We combined voltage-sensitive dye imaging with extracellular multielectrode recordings to study whisker stimulation-induced LTP in the whisker-to-barrel cortex pathway of the neonatal rat barrel cortex in vivo . Single whisker stimulation at 2 Hz for 10 min induced an age-dependent expression of LTP in postnatal day (P) 0 to P14 rats, with the strongest expression of LTP at P3–P5. The magnitude of LTP was largest in the activated barrel-related column, smaller in the surrounding septal region, and no LTP could b…
Reading changes in children and adolescents with dyslexia after transcranial direct current stimulation.
2016
Noninvasive brain stimulation offers the possibility to induce changes in cortical excitability and it is an interesting option as a remediation tool for the treatment of developmental disorders. This study aimed to investigate the effect of transcranial direct current stimulation (tDCS) on reading and reading-related skills of children and adolescents with dyslexia. Nineteen children and adolescents with dyslexia performed different reading and reading-related tasks (word, nonword, and text reading; lexical decision; phonemic blending; verbal working memory; rapid automatized naming) in a baseline condition without tDCS and after 20 min of exposure to three different tDCS conditions: left …
The importance of the insular cortex for vestibular and spatial syndromes.
2020
BACKGROUND AND PURPOSE The aim of the study was to identify the neuroanatomical correlates and associations of neuropsychological syndromes after acute unilateral right-hemisphere brain lesions. The neuropsychological syndromes considered were orientation in three-dimensional space such as tilts of the subjective visual vertical or of the subjective haptic vertical, pusher syndrome, visual neglect and unawareness of paresis (anosognosia for hemiparesis). These neuropsychological phenomena have been found to occur separately or in different combinations after lesions to the right insular cortex. METHOD Magnetic resonance imaging scans were obtained from 82 patients with acute right-hemispher…
Il decreto ingiuntivo emesso nei confronti del condominio deve essere notificato in forma esecutiva al singolo condomino debitore
2017
L'articolo, attraverso l'esame di una pronuncia della Corte di Cassazione, si occupa della tematica dei rapporti tra condominio e condomino nell'ambito del procedimento esecutivo e, in particolare, della notifica del titolo esecutivo The article, through the examination of a decision of the Court of Cassation, deals with the issue of the relationship between condominium and condominium in the context of the executive procedure and, in particular, of the notification of the enforceable title
Atenuación e intensificación pragmáticas en la expresión de actividades de imagen: Un estudio contrastivo en conversaciones coloquiales del español y…
2015
El presente es un estudio contrastivo basado en conversaciones coloquiales reunidas en dos corpus orales, uno del español peninsular y otro del inglés norteamericano. Se centra en las actividades de imagen de los interlocutores llevadas a cabo mediante mecanismos de atenuación e intensificación. Se han estudiado, por tanto, no solo las actividades de imagen dirigidas al oyente (actividades de cortesía), sino también las actividades de autoimagen. Consideramos que el análisis de ambos tipos de actividades de imagen nos permite obtener una visión más completa, y así, más veraz, del trabajo de la imagen en relación con las bases culturales. El análisis de los datos se ha realizado sobre materi…
Las actividades de imagen y el funcionamiento de la atenuación en correos electrónicos del ámbito empresarial: un estudio contrastivo de los estilos …
2022
Esta tesis trata de investigar y determinar diferencias y semejanzas sociopragmáticas en el modo en que se configuran las actividades de imagen y la atenuación en correos electrónicos del ámbito de las empresas de españoles y brasileños. Los dos objetivos generales de este trabajo consisten en: i) elaborar un corpus lingüístico especializado y representativo de correos electrónicos del entorno de las organizaciones en portugués y en español y ii) verificar la influencia de determinadas variables enunciativas, estructurales y situacionales en la manifestación de las actividades de imagen y de la atenuación usadas en dicho corpus. Para ello, en primer lugar, se repasan algunos estudios acerca…
Evolución de la imagen de rol familiar en el teatro de finales del siglo XIX a mitad del XX. Su manifestación en la atenuación e intensificación de l…
2019
La presente investigación se inserta en la incipiente disciplina de la pragmática histórica del español, específicamente en la corriente de los estudios diacrónicos de corte onomasiológico. El objetivo general de esta tesis doctoral ha sido describir la evolución de las imágenes de los roles sociales familiares en un periodo concreto de la historia social española: desde finales del siglo XIX hasta la década de los años sesenta del siglo XX. La atención a esta etapa se debe al cambio crucial en la sociedad española que se produce en ella: se consolida la evolución desde una sociedad tradicional a una sociedad moderna, que cristaliza en ciertos cambios en las relaciones familiares El estudio…
Psicobiologia dell'attaccamento
2008
In this work, the emotional and cerebral development of the individual is treated as a complex process, within which genetic and experiential factors interact; equal focus is given to these factors as is through the interactions of both that the human brain achieves full maturity. The recent literature on neuroscientific findings has allowed to understand further which are the mechanisms that play the most important role in the human brain. In particular, this recent work has pointed out the importance of precocious experiences of emotional syntonization between the baby and its development partners; the quality of the experiences that such partners will be able to provide will configure no…
Non-cell autonomous and non-catalytic activities of ATX in the developing brain
2015
The intricate formation of the cerebral cortex requires a well-coordinated series of events, which are regulated at the level of cell-autonomous and non-cell autonomous mechanisms. Whereas cell-autonomous mechanisms that regulate cortical development are well-studied, the non cell-autonomous mechanisms remain poorly understood. A non-biased screen allowed us to identify Autotaxin (ATX) as a non cell-autonomous regulator of neural stem cell proliferation. ATX (also known as ENPP2) is best known to catalyze lysophosphatidic acid (LPA) production. Our results demonstrate that ATX affects the localization and adhesion of neuronal progenitors in a cell autonomous and non-cell autonomous manner, …
Increased Gamma Connectivity in the Human Prefrontal Cortex during theBereitschaftspotential
2017
The Bereitschaftspotential (BP) is a slow negative cortical potential preceding voluntary movement. Since movement preparation is dependent upon the synchronous activity of a variety of neurons, BP may develop through the exchange of information among motor-related neurons. However, the relationship between BP and information flow is not yet well-known. In the present study, we aimed to investigate how the connectivity in the prefrontal cortex (PFC) changes during the occurrence of BP. Electrocorticography (ECoG) was recorded in five patients with epilepsy. The subjects performed self-paced hand grasping. We compared the intraregional connectivity between PFC and non-PFC regions using parti…
