Filter by:During hospital stay, a family centered therapeutic approach is increasingly seen as the preferred clinical and care model to be adopted, since it is effective in promoting the neurobehavioral development of the infant and the psychophysical health of the family. In preterm infant, parental relationship and parental relationship-centered interventions, such as kangaroo mother care (KMC), are actively promoted. Studies carried out with electroencephalography showed that preterm infants who participated in KMC interventions have, when reach term equivalent age, a similar level of maturity as healthy full-term infants. It has also been observed that KMC carried out in preterm infant with gestational age <33 weeks promotes adequate development of the primary motor cortex during adolescence. Recent scientific evidence showed an early response to relational stimulations, in particular to their emotional content, of term infants. After few days of life, the infant's brain picks up messages from the human context and interacts with them. For example, a study using near-infrared spectroscopy (NIRS) showed increased activation of the right frontal cortex in infants in association with their mother's direct speech. Similar neuroimaging studies have not yet been conducted in preterm infants during hospitalization. The aim of this study is to assess the activation of the cerebral cortex of the preterm infant in the course of 1) KMC and 2) listening to their mother's voice, using optical topography, a multichannel NIRS system.
Proof of effectiveness of Pascoflair using qantitative measurement of electric brain activity during examination stress in 40 subjects suffering from test anxiety. A double-blind, randomized, placebo-controlled, 2-armed, Phase IV study in parallel design.
The main objective of this project is: 1. To assess the influence of physical fatigue on brain functioning during a balance and reaction time task in a healthy population. In a later stage, these experiments could be carried out in a clinical context (e.g. in an ankle sprain population). The researchers will use a randomized, placebo controlled, counter-balanced, cross-over design. Twenty healthy subjects will visit the lab 3 times. On the first visit (familiarisation trial), the investigators will collect the participants' characteristics. The participants will also be familiarized to the procedures and materials of the experiment during this first visit. The second and third visit contain the experimental setup and will proceed as follows: first, the participants will fill in a pre-test checklist, a mental fatigue scale (M-VAS) and motivation scale. In the mean time a little blood will be collected from the ear lobe to determine lactate and glucose levels; also, blood pressure will be checked. Next, the subjects will carry out a Y-balance test and a balance reaction-time test. Session rate of perceived exertion (SRPE) is measured to indicate how fatigued the participants feel due to the test battery; also, M-VAS is collected once more, as well blood lactate, glucose and blood pressure. These measures are followed by either a physical fatigue inducing task (Modified 30 seconds Wingate protocol) or time-matched control task (sitting on the bike without pedalling). Afterwards, researchers will collect blood lactate, glucose and blood pressure two times more; participants have to fill in M-VAS (2x), perform the same Y-balance test and balance reaction time test, and fill in the SRPE scale one more time. Heart frequency and EEG will be measured continuously during the trials.
Objective of the study The main objectives of this project are: 1. To assess the influence of mental fatigue on a return-to-play test battery in healthy population 2. To assess the influence of mental fatigue on brain functioning during a balance and reaction time task in healthy population In a later stage, these experiments could be carried out in a clinical context (e.g. in an ankle sprain population). The researchers will use a randomized, placebo controlled, counter-balanced, cross-over design. Thirteen healthy subjects will visit the lab 3 times. On the first visit (familiarisation trial), the investigators will collect the participants' characteristics. The participants will also be familiarized to the procedures and materials of the experiment during this first visit. The second and third visit contain the experimental setup and will proceed as follows: first, the participants will fill in a mental fatigue scale (M-VAS) and motivation scale. Next, the subjects will carry out a functional test battery (hop test, vertical jump test, Y-balance test, and a balance reaction-time test). Session rate of perceived exertion (RPE) is measured to indicate how fatigued the participants feel because of the test battery; also, M-VAS is collected once more. Then, a short cognitive task (Flanker task) is followed by either a long intensive cognitive task (90 minutes Stroop task) or control task (90 minutes documentary). Afterwards, participants have to carry out the Flanker task, fill in M-VAS (2x), perform the same test battery, fill in session RPE and one final fatigue scale (Nasa TLX). Heart frequency and EEG will be measured continuously during the trials.
The objectives of the research are to assess the effects of increased protein and fiber intake at breakfast on neural activation in brain regions associated with appetitive drive and reward-driven eating, measures of subjective appetite, and ingestive behavior in overweight adults. Additional outcomes of interest include the effects of the breakfast intervention on blood sugar and cholesterol profiles.
This study seeks to assess the effects of lisdexamfetamine (trademark name: Vyvanse; LDX) on executive function and prefrontal cortex activation in menopausal women ages 45-57, who report subjective cognitive difficulties. This protocol will recruit women from Dr. Epperson's ongoing study, Protocol #812470, to examine the impact of LDX on brain activation during performance of cognitive tasks specifically probing prefrontal cortex function.
The purpose of the study is to evaluate whether low-dose USP methylene blue (MB) will: i) improve short-term memory retention in a delayed match-to-sample task, ii) reduce reaction time in a psychomotor vigilance test, and iii) enhance responses to a visual-motor task as measured by functional magnetic resonance imaging (fMRI). A single low-dose MB or placebo will be orally administered to self-declared healthy adults using double-blind study design. Non-invasive fMRI data will be acquired before and after MB administration in the same subjects. Each study will take 2-3 hours, inclusive of an hour break in between.
The study included analysis of longitudinal recordings of amplitude-integrated EEG (aEEG) tracings on a weekly basis in preterm infants and evaluation of their neurodevelopmental outcome at the age of three years. Aim of the study was to observe if there is a correlation of the aEEG tracings of the first weeks of life to later neurodevelopmental outcome and to evaluate if aEEG can be used as prognostic tool.
