So… we just found out that GPT sol can complete a complex online behavioral/cognitive study producing nearly indistinguishable behavior and subjective reports… right as we are about to launch. Is this doomsday for online cognitive testing?

They also suggest that previous MEG/EEG hyperscanning findings should be interpreted with particular caution, given the sensitivity of commonly used metrics to frequency mismatch and SNR.

Juan Camilo Avendano-Diaz @juancamiload.bsky.social · 29/07/2026
Overall, our findings highlight the need to develop or adopt connectivity metrics specifically tailored to hyperscanning datasets.
100
Juan Camilo Avendano-Diaz @juancamiload.bsky.social · 29/07/2026
The accuracy of inter-brain connectivity estimates was also modulated by the signal-to-noise ratio (SNR), adding to previous calls to carefully consider SNR differences between experimental conditions when interpreting intra- and inter-brain connectivity results.

Juan Camilo Avendano-Diaz @juancamiload.bsky.social · 29/07/2026
Common mitigation strategies used in single-brain analyses, such as adjusting the frequency band definition to better align with individual alpha peaks, varying the number of wavelet cycles, or varying the epoch length within recommended ranges, did not mitigate the effect of frequency mismatch.
100
Juan Camilo Avendano-Diaz @juancamiload.bsky.social · 29/07/2026
Frequency mismatches typically present in the population can lead to substantial misestimations of inter-brain connectivity in a large proportion of dyads, which could compromise subsequent interpretations and potential links to social interaction.
100
Juan Camilo Avendano-Diaz @juancamiload.bsky.social · 29/07/2026
Our findings highlight a critical methodological limitation in the MEG/EEG hyperscanning literature: phase-based connectivity metrics commonly used to examine inter-brain synchrony are highly sensitive to differences in participants’ oscillatory peak frequencies.
100
Juan Camilo Avendano-Diaz @juancamiload.bsky.social · 29/07/2026
Here, we simulated oscillatory MEG/EEG signals from two participants to systematically investigate how inter-individual differences in oscillatory peak frequencies affect estimates of inter-brain functional connectivity.
100
Juan Camilo Avendano-Diaz @juancamiload.bsky.social · 29/07/2026
However, spontaneous neural oscillations vary in their peak frequencies, not only between individuals, but also within individuals across brain areas and tasks.
100
Juan Camilo Avendano-Diaz @juancamiload.bsky.social · 29/07/2026
Most EEG and MEG hyperscanning studies rely on phase-based connectivity metrics originally developed to quantify frequency-specific synchronization between signals within a single brain. These metrics assess dependencies between oscillations at the same frequency.
100
Juan Camilo Avendano-Diaz @juancamiload.bsky.social · 29/07/2026
Hyperscanning studies typically estimate interdependencies between the brain signals of interacting individuals using functional connectivity metrics. The core assumption is that synchronization of brain activity between individuals reflects aspects of social interaction.
100
Juan Camilo Avendano-Diaz @juancamiload.bsky.social · 29/07/2026
Hyperscanning—the simultaneous recording of brain activity from multiple individuals—and the study of inter-brain synchronization are becoming increasingly popular in social neuroscience.

The cognitive side of communication in social insects
Social insects rely on multiple communication channels. These channels have traditionally been considered innate, eliciting stereotyped responses. However, recent research has shown that cognitive modulation occurs in communication contexts long assumed to be entirely genetically encoded, thus revealing a previously unrecognized cognitive plasticity in social insect communication.

🚨🚨🚨PREPRINT ALERT🚨🚨🚨 Neural dynamics across cortical layers are key to brain computations - but non-invasively, we’ve been limited to rough "deep vs. superficial" distinctions. What if we told you that it is possible to achieve full (TRUE!) laminar (I, II, III, IV, V, VI) precision with MEG!
Overview of the simulation strategy and analysis. a) Pial and white matter boundaries
surfaces are extracted from anatomical MRI volumes. b) Intermediate equidistant surfaces are
generated between the pial and white matter surfaces (labeled as superficial (S) and deep (D)
respectively). c) Surfaces are downsampled together, maintaining vertex correspondence across
layers. Dipole orientations are constrained using vectors linking corresponding vertices (link vectors).
d) The thickness of cortical laminae varies across the cortical depth (70–72), which is evenly sampled
by the equidistant source surface layers. e) Each colored line represents the model evidence (relative
to the worst model, ΔF) over source layer models, for a signal simulated at a particular layer (the
simulated layer is indicated by the line color). The source layer model with the maximal ΔF is
indicated by “˄”. f) Result matrix summarizing ΔF across simulated source locations, with peak
relative model evidence marked with “˄”. g) Error is calculated from the result matrix as the absolute
distance in mm or layers from the simulated source (*) to the peak ΔF (˄). h) Bias is calculated as the
relative position of a peak ΔF(˄) to a simulated source (*) in layers or mm.
