I don't think I'll ever get bored of looking at raster plots of head-direction cells 🤩

the cutoff scores for #MSCA postdoc fellowships are very high this year. has the score distribution shifted compared to previous years? I made a plot with scores from past years.
if scores are at ceiling level, the process becomes essentially a lottery, because minor issues can lead to deductions.

interesting oscillation peak frequency shifts under LSD compared to placebo, with power vs. frequency dissociation: regions that attenuated a lot in power, shifted relatively little in frequency & vice versa.
1/f-fits appear worse for LSD condition, implications of this would be interesting. 🤔

✨ Key result #1:
LSD speeds up brain rhythms
Across the cortex, intrinsic alpha & beta #oscillations shift to faster frequencies.
👉 What often looks like reduced spectral power is largely explained by shifts in peak frequency, not just a loss of rhythmic structure.

Before mice open their eyes at two weeks old, the retina exhibits spontaneous retinal waves. Waves at the start of the second postnatal week show a bias to propagate in the nasal direction (or right to left in the movie below). (2/11)

it's easy to create custom feeds for bluesky based on regular expressions, here's an attempt for rhythms in the brain:

feeds with a curated user list amplify often the same high-profile posters, I feel this maybe has a better chance of catching more obscure content.

I def agree that there are multiple alpha rhythms. (I think the whole field agrees?)
here, fixed 'archetypal' alpha components are identified & peak frequency variation across subjects is explained by relative contribution of archetypal components within a subject.
interesting, but maybe odd?

🚨 New preprint! What if individual alpha peak frequency—often treated as a global marker of brain function and clinical phenotypes—actually reflects a mixture of independent alpha rhythms with distinct frequencies and neural origins? That’s what @davidpascucci.bsky.social and I suggest here. #EEG

if you look into the activity of any brain, usually many different rhythms can be seen. is there any systematic relationship between their frequencies? there are proposals (often by physicists 🙃) that rhythms are organized according to specific ratio, e.g. the golden ratio or simply factor 2.

ripple researchers probably open this article with sweaty palms, because ripple detection with 77% false positives for standard processing sounds pretty bad... 😨
Ripple oscillations are central for memory and sleep.
But ripple detection in humans remains challenging. Here we introduce a simulation approach in @natcomms.nature.com as common ripple detectors mainly pick up 1/f noise and not genuine oscillations

Interpreting EEG requires understanding how the skull smears electrical fields as they propagate from the cortex. I made a browser-based simulator for my EEG class to visualize how dipole depth/orientation change the topomap.

in my experience, phase efects for sensorimotor mu-alpha rhythms can come out very clear. but for visual alpha there are definitely less consistent results... taking individual variability into account seems like a step in the right direction to me.
The key to understanding alpha phase and perception
Individual differences!
Our Neurobehavioral Link Function (NBLF) models how each person's alpha phase uniquely modulates multisensory perception and proves causality.

this paper shows 8 Hz oscillatory patterns in spontaneous unit activity, with spikes appearing at a regular pattern. so naturally, I was intrigued + downloaded the data + saw for myself. 🙂 really pretty! (but there is only 1 unit like this, out of ~15)

fun old experiment (1968): O. Lippold believed that the alpha rhythm was related to the physiological tremor in eye muscles (also ~10 Hz). so in this experiment, the eyeball was cooled & warmed to shift the muscle tremor frequency. when they measured EEG, the alpha frequency seems to change.
