How many sources does it take to produce a travelling wave in the EEG/MEG? Two. Our study from the @TheCHBH lead by @zhigalov_ax. While possibly disappointing, it does create a possibility for studying occipito-parietal communication. https://t.co/MCRFRycvTT

Our MEG study on statistical learning of distractor suppression using frequency tagging is finally out on @SfNJournals. Together with @zhigalov_ax, Clayton Hickey and Ole Jensen (@neuosc) 🥳🥳🥳 https://t.co/4EMNnbbpEL

Visual attention is highly influenced by past experiences. Recent behavioral research has shown that expectations about the spatial location of distractors within a search array are implicitly...

How many sources does it take to explain travelling alpha waves ('perceptual echoes') in EEG/MEG data? Answer: two (shifted in phase). Our new @TheCHBH study by @zhigalov_ax : https://t.co/Om8rdKhnbK
biorxiv.org
Growing evidence suggests that travelling waves are functionally relevant for cognitive operations in the brain. Several electroencephalography (EEG) studies report on a perceptual alpha-echo,...

Among other things, that Ukrainians in 🇫🇮 are preparing for supply to Ukraine 🇺🇦 is food for our infants/toddlers over there who are in shelters right now. We must leave our kids the better world! The support from Finnish/international friends is impressive! #WeStandWithUkraine

That’s very interesting! Apparently, if you stimulate normal people with random visual flicker, you can get a gamma-band response. Surprisingly, you can even model this response 😊 All details are here,
journals.plos.org
Author summary The properties of the neuronal dynamics governing the visual system are highly debated. While some emphasize the neuronal firing rate and evoked activity in response to visual stimuli,...

Super interesting study on the gamma-band echo!
The human visual cortex generates an echo in the gamma band (akin to VanRullen's perceptual echo in the alpha band). MEG results + a physiologically plausible PING model:

I am happy to share our new study published in Human Brain Mapping
Surprise - alpha oscillations do not seem to implement gain control in early visual cortex but rather gating in parieto‐occipital regions. Our new MEG study from @theCHBH using a new technique: rapid broad-band frequency tagging https://t.co/aXpcH1niwz

We are excited to share our new manuscript: "Alpha oscillations do not implement gain control in early visual cortex but rather gating in parieto-occipital regions" where we apply broad-band frequency tagging >60 Hz https://t.co/qvxsuc18WJ

Spatial attention provides a mechanism for respectively enhancing relevant and suppressing irrelevant information. While it is well-established that attention modulates oscillations in the alpha...
