Visual-Evoked Potential (VEP) Event-Related Files from the General Anesthesia and Brain Activity (GABA) Study and Infant Sibling Project (ISP)
<p>HAPPE+ER software was optimized for developmental data using a subset of EEG files from 4-month and 10-month old infants in the General Anesthesia and Brain Activity (GABA) Study. While medically necessary, 1-2 million infants each year undergo general anesthesia – a process that sedates brain activity and impacts early sensory experiences during a time typically characterized by rapid neurocognitive development. The GABA study examines sensory and socioemotional neurodevelopment longitudinally from infancy through childhood in individuals who have and who have never undergone general anesthesia during different windows in the first year of life. The GABA study was carried out in accordance with the recommendations of the Institutional Review Board at Boston Children’s Hospital. All caregivers provided assent for their child’s participation in the GABA study and for the release of the deidentified data. </p> <p>To facilitate the use and understanding of HAPPE+ER software, we have provided a subset of the validation files from the GABA study to serve as a tutorial dataset for how to run event-related potential (ERP) data through this automated processing pipeline. Five files (a.raw - e.raw) are from four 4-month and one 10-month old infants during a pattern reversal visual-evoked potential (VEP) paradigm. Pattern reversal occurred every 500 milliseconds. The pattern stimulus onset is indicated in each file by the code: vep+. Data was collected using a 128-channel EGI HydroCel Geodesic Sensor Net and EGI Net Amps 400, sampled at 1000Hz with an online reference to channel CZ. </p> <p>We have also included a subset of files from the Infant Sibling Project (ISP), an investigation examining infants at high versus low familial risk for autism spectrum disorder over the first 3 years of life. Baseline EEG data was collected while a young child sat in a parent’s lap watching a research assistant blow bubbles or show toys for several minutes. The Infant Sibling Project was carried out in accordance with the recommendations of the Institutional Review Board at Boston University and Boston Children’s Hospital (#X06-08-0374), with written informed consent from all caregivers prior to their child’s participation in the study. All files here have been deidentified, including alteration of exact acquisition dates. Acquisition times have not been altered.

To create these files, we selected a subset of 39 spatially-distributed channels in the baseline EEG files and created sixteen 30-second files using continuous segments of relatively artifact-free (clean) baseline data from the full-length files. Next, from 30-second sections of the same individuals’ EEG that were artifact-laden, we ran ICA and extracted artifact independent components (identified by an expert and labeled artifact by both ICLabel and MARA automated algorithms). We inserted the artifact ICs into that individual’s clean 30-second data segment to create an additional 16 artifact-added files. We then selected a channel from a simulated VEP dataset (included here as simulated_full.set) with a stereotyped and prominent simulated VEP waveform, in this case Oz, and added its timeseries (included here as simulated_singleChan.set) to each channel of the clean and artifact-added files to create two VEP datasets with a known ERP morphology (sim-artifact_a-p and sim-clean_a-p). For additional information about the creation of this simulated data and VEP data with a known ERP morphology, please refer to Monachino et al., in revision; DOI: https://doi.org/10.1101/2021.07.02.450946.</p> <p>Additional files included below are the HAPPE+ER data and pipeline quality metric output spreadsheets for the five GABA study data files for an example run, the output spreadsheet containing the ERP timeseries from the generateERPs script, the .mat file containing the parameter settings for HAPPE+ER for that run, an Excel file with the bad channels for each file, and a tutorial document illustrating the results of this example run. </p>

Investigating the relation between gravitational wave tests of general relativity
<p>This data release accompanies the paper Johnson-McDaniel et al., Investigating the relation between gravitational wave tests of general relativity, arXiv:2109.06988.</p> <p>It provides the frame files containing the simulated observations of GR and non-GR signals (with no noise) analyzed in that paper. Specifically, these are simulated observations of binary black hole coalescences like GW150914 and GW170608.</p> <p>Each directory inside one of the tarballs corresponds to a given simulated observation and contains three frame files, one for each observatory (LIGO Hanford, LIGO Livingston, and Virgo). The GR cases contain simulated observations generated using the IHES EOB and IMRPhenomD models, while the non-GR cases contain the modified EOB, TIGER, FTA, and modified dispersion relation (MDR) simulated observations, as described in the paper. Specifically, the TIGER and FTA cases modify the 2PN coefficient, while the MDR cases are for a massive graviton. For the GW150914-like simulated observations, there are two selections (one large, one smaller) of the non-GR parameter for each non-GR case.</p> <p>The frame files in the GW150914-like (GW170808-like) cases contain 8 (16) seconds of data, starting from a GPS time of 1126259456 (1180922480). In both cases, the peak of the waveform (the "trigger time") is placed 2 seconds from the end of the data segment, so at GPS times of 1126259462 and 1180922494 for the GW150914-like and GW170608-like cases, respectively.</p> <p>Any publication that uses these data should cite the aforementioned paper that describes them (arXiv:2109.06988), as well as this Zenodo release, doi:10.5281/zenodo.5637361.</p> <p>Contents:</p> <p>GW150914_like_GR.tgz:<br> - GW150914_like_IHES_EOB_GR<br> - GW150914_like_IMRPhenomD_GR</p> <p>GW150914_like_nonGR_larger.tgz:<br> - GW150914_like_IHES_EOB_modGR_a2_400<br> - GW150914_like_IMRPhenomD_TIGER_dchi4_m13<br> - GW150914_like_IMRPhenomD_FTA_dchi4_m13<br> - GW150914_like_IMRPhenomD_MDR_alpha0_A_5em44</p> <p>GW150914_like_nonGR_smaller.tgz:<br> - GW150914_like_IHES_EOB_modGR_a2_40<br> - GW150914_like_IMRPhenomD_TIGER_dchi4_m2<br> - GW150914_like_IMRPhenomD_FTA_dchi4_m2<br> - GW150914_like_IMRPhenomD_MDR_alpha0_A_1em44</p> <p>GW170608_like_GR.tgz:<br> - GW170608_like_IHES_EOB_GR<br> - GW170608_like_IMRPhenomD_GR</p> <p>GW170608_like_nonGR.tgz:<br> - GW170608_like_IHES_EOB_modGR_a2_40<br> - GW170608_like_IMRPhenomD_TIGER_dchi4_m2<br> - GW170608_like_IMRPhenomD_FTA_dchi4_m2<br> - GW170608_like_IMRPhenomD_MDR_alpha0_A_1em43</p>
Data for: General cognitive performance declines with female age and is negatively related to fledging success in a wild bird
<p class="Affiliation"><span>Identifying the causes and fitness consequences of intraspecific variation in cognitive performance is fundamental to understand how cognition evolves. Selection may act on different cognitive traits separately or jointly as part of the general cognitive performance of the individual. To date, few studies have examined simultaneously whether individual cognitive performance covaries across different cognitive tasks, the relative importance of individual and social attributes in determining cognitive variation, and its fitness consequences in the wild. Here, we tested 38 wild southern pied babblers (</span><em><span>Turdoides bicolor</span></em><span>) on a cognitive test battery targeting associative learning, reversal learning and inhibitory control. We found that a single factor explained 59.5% of the variation in individual cognitive performance across tasks, suggestive of a general cognitive factor. General cognitive performance varied by age and sex; declining with age in females but not males. Older females also tended to produce a higher average number of fledglings per year compared to younger females. Analysing over 10 years of breeding data, we found that individuals with lower general cognitive performance produced more fledglings per year. Collectively, our findings support the existence of a trade-off between cognitive performance and reproductive success in a wild bird. </span></p>

The Relational Structure of Emotional Experience: A Novel Paradigm for Characterizing Differences Between Alexithymic and General Online Participants
<p>Youtube: <a href="https://youtu.be/ChKEnoBKwgA">https://youtu.be/ChKEnoBKwgA</a><br><br>In a pioneering nonverbal study exploring emotional experiences, researchers investigate the nature of alexithymia — a phenomenon where individuals struggle to articulate their emotions. Eschewing traditional verbal reports, the study introduced a unique approach, prompting participants to assess emotional similarities between various stimuli, thereby mapping the "relational structure of emotional experiences". Findings challenge prevailing views on alexithymia, suggesting alexithymic individuals may not just lack words for feelings, but indeed possess distinct emotional experience. This innovative methodology promises not only a deeper understanding of emotional experiences across language and cultural divides but also introduces a potential diagnostic tool for alexithymia.</p>
Distribution. Restricted to the cooler waters of the N Atlantic Ocean from 71° 30" N in the Norwegian Sea, Iceland, and [Labrador (Canada) in the N, to Madeira, Azores, and NE USA to the S; single records from the Gulf of Mexico and E Mediterranean Sea are thought to represent vagrant individuals. In general, this species appears to be more widespread in E Atlantic Ocean than in W Atlantic Ocean, which may be related to preferences for cooler water temperatures. in Ziphiidae
