The Orienting Response in Healthy Aging: Novelty P3 Indicates No General Decline but Reduced Efficacy for Fast Stimulation Rates
2017
Automatic orienting to unexpected changes in the environment is a pre-requisite for adaptive behavior. One prominent mechanism of automatic attentional control is the Orienting Response (OR). Despite the fundamental significance of the OR in everyday life, only little is known about how the OR is affected by healthy aging. We tested this question in two age groups (19–38 years and 55–72 years) and measured skin-conductance responses (SCRs) and event-related brain potentials (ERPs) to novels (i.e., short environmental sounds presented only once in the experiment; 10% of the trials) compared to standard sounds (600 Hz sinusoidal tones with 200 ms duration; 90% of the trials). Novel and standa…
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 …
Enhancing improvisational music therapy through the addition of resonance frequency breathing : Common findings of three single-case experimental stu…
2018
One core characteristic of active music therapy is the facilitation of emotional expression through the creation of music improvisations. In an attempt to further develop this approach, we created an enhanced form of integrative improvisational music therapy by including 10 minutes of resonance frequency breathing (RFB) at the beginning of the sessions. RFB is a type of slowbreathing known for its ability to reduce stress and support emotional regulation. This paper summarizes the common findings of three single-case experimental studies and introduces a provisional model to explain the observed effects of RFB. During the breathing itself, all three clients (two of them healthy and one diag…
RELACIÓN ENTRE EL PROCESAMIENTO SENSORIAL Y LA SEVERIDAD DE LA SINTOMATOLOGÍA EN UNA MUESTRA DE NIÑOS CON TEA
2014
Abstract:RELATION BETWEEN SENSORY PROCESSING AND SEVERITY OF SYMPTOMS IN A SAMPLE OF CHILDREN WITH ASDThe new DSM-5 criteria include the alterations of sensory perception as a new diagnostic criterion to consider in the ASD population. Considering the inclusion of this new approach, the purpose of this study is to compare the features of sensory processing among a group of children (from 5 to 8 years old) with and without ASD. In addition to this, in the case of the ASD group, possible relationships between the sensory processing and the severity of symptoms, assessed by the GARS-2, are analyzed. To do this, the parents of 84 children (41 with ASD diagnosis and 43 with typical development),…
Experiences of people with memory disorders and their spouse carers on influencing formal care: “They ask my wife questions that they should ask me”
2021
Background People with memory disorders often need care and help from family carers and health and social care providers. Due to the deterioration of cognitive capacity and language skills, they may be unable to convey their thoughts and care preferences to other people. As a result, their agency may become restricted. We investigated the descriptions provided by people with memory disorders and spousal carers of their influence on care in encounters with formal care providers. Methods Qualitative thematic analysis was used to identify, analyze, and report themes that describe encounters with professionals in different social or healthcare environments. In-depth interview data were gathered…
Dimensionality and Measurement Invariance of the Italian Version of the EORTC QLQ-C30 in Postoperative Lung Cancer Patients
2019
Background: This study aims to validate and evaluate the psychometric properties and measurement invariance of the Italian version of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30), which is a measure of quality of life (QoL) for lung cancer patients after surgery. Methods: A total of 167 lung cancer patients completed the Italian version of the EORTC QLQ-C30 questionnaire at 30 days after they received a lobectomy. The factor structure of this scale was assessed by performing confirmatory factor analysis (CFA). Measurement invariance was evaluated by considering differential item functioning (DIF) due to age, gender, a…
Event-related potentials to unattended changes in facial expressions: detection of regularity violations or encoding of emotions?
2013
Visual mismatch negativity (vMMN), a component in event-related potentials (ERPs), can be elicited when rarely presented “deviant” facial expressions violate regularity formed by repeated “standard” faces. vMMN is observed as differential ERPs elicited between the deviant and standard faces. It is not clear, however, whether differential ERPs to rare emotional faces interspersed with repeated neutral ones reflect true vMMN (i.e., detection of regularity violation) or merely encoding of the emotional content in the faces. Furthermore, a face-sensitive N170 response, which reflects structural encoding of facial features, can be modulated by emotional expressions. Owing to its similar latency …
P258 Combining tDCS with prismatic adaptation for non invasive neuromodulation of the motor cortex
2017
Introduction Prismatic adaptation (PA) shifts visual field laterally and induces lateralized deviations of spatial attention. Recently, it has been suggested that prismatic goggles are also able to modulate brain excitability ( Magnani, 2014 ), with cognitive after-effects documented even in tasks not necessarily spatial in nature ( Oliveri, 2013 ). Objectives The aim of the present study was to test whether prisms can modulate motor cortical excitability similarly as anodal transcranial direct current stimulation (tDCS) does; to test whether neuromodulatory effects obtained from tDCS and prismatic goggles could interact and induce homeostatic changes in brain excitability. Materials and me…
EFFICACY OF REPETITIVE TRANSCRANIAL MAGNETIC STIMULATION/TRANSCRANIAL DIRECT CURRENT STIMULATION IN COGNITIVE NEUROREHABILITATION
2008
Summary: Cognitive deficits are a common consequence of neurologic disease, in particular, of traumatic brain injury, stroke, and neurodegenerative disorders, and there is evidence that specific cognitive training may be effective in cognitive rehabilitation. Several investigations emphasize the fact that interacting with cortical activity, by means of cortical stimulation, can positively affect the short-term cognitive performance and improve the rehabilitation potential of neurologic patients. In this respect, preliminary evidence suggests that cortical stimulation may play a role in treating aphasia, unilateral neglect, and other cognitive disorders. Several possible mechanisms can accou…
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…
