Sentences with phrase «eeg power»

For the purposes of the present analyses, EEG power in the alpha band at 8 y was created by computing an unweighted average of alpha power across hemisphere and brain region.

First, we examined the relationships of plausible covariates, including gender, birth - weight, post-conceptual age on the visit day (gestational age + days of life since birth to the visit day), ethnicity, prenatal smoking exposure, and child sleep condition at the time of EEG recording with outcome measures (frontal EEG power, functional connectivity at 6 and 18 months of age, or behavioral scores at 24 months of age).

When considering social skills, the positive effects of a strong attachment relationship during early childhood are seen in those children whose EEG power is more mature and age appropriate.

Thus, given previous relations to developmental outcomes as well as the intervention and timing effects that have been reported, EEG power in the alpha band at age 8 was examined in the current study.

To examine our first aim, separate regression models were used to evaluate each frontal EEG measure (dependent variable; frontal EEG power: FL, FR, and FA; functional connectivity: FL, FR, and FA), and each behavioral score (dependent variable; internalizing and externalizing score) in relation with pre - or post-natal maternal EPDS score (independent variable).

DHEAadministration increases rapid eye movement sleep and EEG power in the sigmafrequency range.

We assessed the degree of similarity of EEG power - BOLD broad - spectrum between rest and movie across nine cortical language regions.

Colrain, I. M., Turlington, S., and Baker, F.C. Impact of Alcoholism on Sleep Architecture and EEG Power Spectra in Men and Women.

Not exact matches

It seems a complicated way of assessing sex, using EEG and strong computing power.

In recent years scientists have dramatically improved the power of EEG by writing computer programs that compare recordings from multiple locations around the head and then calculate which regions of the brain are producing the signals.

The simultaneous EEG and fMRI recordings allowed us to explore how theta power fluctuations driven by the movie correlate with local synaptic activity in auditory cortex, as indexed by the BOLD signal (Magri et al., 2012; see Materials and Methods).

If we should have luck here in Germany, and the EEG does not fail, it would mean that in 20 years we'd have a grid mostly powered by renewable energy, paid by the private households alone, that will produce cheap electricity for the industry at a time when oil, gas and coal will be much more expansive than today.

Renewables also lower the price of power during the middle of the day by significant amounts — but increase household bills via the EEG surcharge, the group said.

But against the backdrop of the decade - long nuclear contests, the FIT system (as established by the EEG in 1991) that obligated supply companies to purchase wind, solar, and biomass power and then pass costs to consumers was fueling tremendous growth of renewables.

The EEG required utility companies to plug all renewable power producers, down to the smallest rooftop solar panel, into the national grid and buy their power at a fixed, slightly above - market rate that guaranteed a modest return over the long term.

But whenever the wholesale price is lower than the feed - in tariff (which it is most of the time), the difference is made up from the renewable energy surcharge (EEG surcharge), a levy that almost all consumers pay with their power bills.

Under the Renewable Energy Act, which has been imitated around the world, any renewable power investor — be it a household installing a solar array on the roof, a cooperative erecting a windmill, a farmer running a biogas installation, or an institutional investor operating an offshore wind park — could sell their green electricity at a guaranteed price above wholesale market price, fixed in advance for 20 years (for more details, see the factsheet Defining features of the Renewable Energy Act (EEG)-RRB-.

Whilst there had been discussions on how much feed - in tariffs should decrease for the different technologies and about different ways to integrate renewables into the national grid and power market before, the first time that the existence of the EEG and its principles were seriously contested was in 2012/2013.

More recently, people have started harnessing EEG as a way to power devices or «read minds» (spoiler: they can't actually read your mind).

Consumer EEG tends to pick up a lot of false positives, like signals from muscles, or even the electricity that powers the device itself.

What has not been examined is how such variation in EEG activity (e.g., alpha power) among children who have experienced severe social deprivation early in life is associated with the development of social skills and the effects of early attachment experiences on those social skills.

Regression analyses examining attachment security and EEG alpha power in relation to social skills were conducted using the FCG and CAUG combined.

Overall, the present study had three main goals: (i) to compare the social skills of children randomized to foster care intervention and children randomized to continued institutional care with those of children from the community; (ii) to determine whether the timing of the foster care intervention influenced social skills; and (iii) to examine the influence of early attachment experiences and the moderating influence of EEG alpha power at 8 y on social skills in middle childhood for children who had experienced any early institutionalization (the FCG and the CAUG).

Thus, just as the early experience of being institutionalized influenced ADHD symptomatology through effects on EEG alpha power at baseline (9), the experience of forming a more secure attachment relationship combined with a recovery of EEG alpha power by age 8 influenced social skill development in the current analysis.

Finally, 10 - minute EEG data from the auditory oddball task for each subject were extracted for spectral power and brain functional network analyses below.

We found that children's EEG alpha power emerged as a significant moderator of the relation between attachment security and social skills in the school setting.

We provide data that show the role of EEG alpha power on the relations between attachment security and subsequent social skills.

Compared to the frontal FC measure, the frontal EEG activity measure had less statistical power in predicting children's behaviors at 24 months of age in our study.
