Beta oscillations can be subdivided into low beta (13-20 Hz) and high beta (20-30 Hz). This paper nicely demonstrates dissociation using Hidden Markov Models. While low beta is completely suppressed during movement, high beta shows variability. Post-movement rebound is dominated by low beta. Cool!👍

Neurons x time points is higher-dimensional data. It can be reduced to a lower-dimensional manifold. This review gives an introduction, explanation, and summary of current evidence on neuronal manifolds. I appreciated the discussion of emergence: is the manifold more than the sum of its parts?

Plateau potential is exactly what it sounds like: the neuron membrane potential that increases a bit and stays in this depolarized state for ~500 ms. This paper found that pyramidal neurons in V1 L5 have those plateau potentials, and they are related to behavioral plasticity. V. weird but cool!👏

Recently, I was playing with extracting brain activity using ICA (I know that some use SSD, but I use ICA).
Here's one example from the dataset with somatosensory stimulation. There are several components over the right somato-motor area (where the brain responds to stimulation).🧐

Aperiodic spectra under anti-epileptic drugs (presumably reduced excitation). No good news for 1/f slope, but the offset was decreased. Cool!👏 Found something for myself: alpha power seems to be reduced under lamotrigine but not levetiracetam, and only in eyes-open but not in eyes-closed condition.🤔

Proposed model returns uncertainty representations (confidence) based on input sensory signals. Tested on auditory perception. Cool!👍 It means that if one has data without confidence ratings, the model can give at least an estimate. I wonder how easy it could be to adapt it to somatosensory domain.

Optically pumped magnetometers (OPMs) can capture a 140 Hz retinal response to a flash of light. Super!👏 It's not that I study high gamma at 200 Hz or high frequency oscillations at 600 Hz, and it's not that I have convenient access to OPMs, but it's encouraging to see the OPMs' increased bandwidth.

Nice piece about extreme multiverse analysis! The exemplar study performed 3.6 billion regression models. The author argues against this approach and suggests that multiverse analysis should only include valid models selected based on theories. Statistical inference requires thinking before acting🤓

People come and people go,
In a monotonic flow.
Finally, I have a guest,
Demonstrating interest.
I would show him alpha waves,
How they are dispersed in space.
Then the myelin content maps,
Cut across the cortex’s depths.
And relation that I found
With interpretation round.

I always learned a great deal from simulating data (aka mostly how things don't really work the way they are advertised 🙃).
so I can definitely recommend playing with this toolbox for simulating EEG/MEG sources with desired properties (location, coupling) for connectivity. ⬇️

We (I and @willenjoy.bsky.social) created a toolbox for simulations of EEG/MEG because we needed to simulate data. Our initial aim was to simulate connectivity. For this short clip, I simulated two sources with phase connectivity using our toolbox.

Second day at the Brain Quantum Imaging symposium: Ole Jensen about reading.
Two interesting things: 1) when reading, alpha rhythm power remains strong (not stronger than resting but still there); 2) alpha may be involved in visuomotor coordination.🤔

One highlight is Saskia Helbling on whether we can infer laminar origin of signals with OPMs. Answer: there are many things to consider.

Great overview conceptualizing approaches for studying sensory conscious perception👏. I, myself, had research experience with both subjective and objective approaches, but it was nice to learn the great landscape and where I land. Table 1 is especially informative.
Pre-print 🎉 "Subjective and objective approaches in the study of conscious perception" will be a chapter in www.horizon-minds.com. We explain that subjective and objective are poorly defined constructs and provide a taxonomy.

Nick (@willenjoy.bsky.social) is obsessed with signal-to-noise ratio (SNR). And for good reason! It could explain many results. Our simulation toolbox meegsim enables setting up SNR of individual sources as well as SNR of all signal sources with respect to all noise sources.

When target for reaching varies in certainty of its position, it is pre-motor cortex (PMd) that codes uncertainty, not primary motor cortex (M1). Also, preparatory activity for left and right movements becomes similar with high uncertainty. Cool!👍 Now I know why I'm so stupid when hitting the ball.🎾
