Aperiodic activity reflects pathological waveforms in epilepsy (and not necessarily hyper-excitability or altered E/I-balance). The 1/f slope goes up *or* down as function of waveforms during seizures. New work by Laura Heidiri and Frank van Schalkwijk from the lab: www.jneurosci.org/content/45/5...

Aperiodic Activity Reflects Pathologic Waveform Shapes in Focal Epilepsy

Epilepsy constitutes a clinically manifest excitability disorder that is characterized by aberrant electrophysiological activity in the electroencephalogram (EEG). The correct identification of the se...

How does the brain sample the #visual environment in space and time? @iraposo.bsky.social &co show that two distinct temporal patterns (rhythmic oscillations & aperiodic timescales) predict attention-guided behavior @plosbiology.org 🧪 plos.io/3ThTKVy

Behavioral timescales increase when multiple locations are sampled. Left: Schematic of task designs. Participants fixated a central cross and were presented with a cue, which indicated the location participants should covertly attend to. After a variable cue-target interval a target appeared in either the cued or non-cued location and participants responded with a button press. In the first task participants only had to sample two locations, while in the second task, participants had to sample four locations. Second left: demeaned, time-resolved RTs as a function of the cue-target interval for one exemplary participant (two locations: red; four locations blue). Second right: power spectrums with different peak frequencies. Right: the autocorrelation function and the respective timescales.
