Oscillatory Markers of Interoceptive Attention: Beta Suppression as a Neural Signature of Heartbeat Processing

open access: yesPsychophysiology, Volume 63, Issue 5, May 2026.
ABSTRACT Interoceptive attention refers to selectively attending to internal bodily signals to guide perception and behavior. Cardiac interoception, in particular, has been proposed to play a key role in self‐regulation and emotional awareness, yet the neural dynamics underlying attention to cardiac signals remain incompletely understood.

Kuramoto Model on Sierpinski Gasket I: Harmonic Maps

open access: yesStudies in Applied Mathematics, Volume 156, Issue 5, May 2026.
ABSTRACT Motivated by the study of attractors in the Kuramoto model (KM) on graphs, approximating the Sierpinski gasket (SG), we revisit the problem of harmonic maps (HMs) from SG to the circle, first considered by Strichartz. We provide a geometric proof of Strichartz's theorem, which states that for a prescribed degree and suitable boundary ...

Midline Theta Rhythm

Archives of Neurology, 1986
Thirty-six patients had a midline theta rhythm in the electroencephalogram that consisted of a train of rhythmic waveforms in the theta frequency range (4 to 7 Hz), which occurred as a focal rhythm in the midline leads and was usually most prominent in the central vertex lead.

Parietal focal theta rhythm

Electroencephalography and Clinical Neurophysiology, 1954
Abstract The EEGs of 37 patients are described, in which the only, or major, abnormality was a sharply focal rhythm at 7 ± 2 c/sec., in one or other parietal region; it was not much affected by eye-opening, startle, or overbreathing, and was usually readily distinguishable from the alpha rhythm, although the difference in frequency might be small ...

Midline Theta Rhythm Revisited

Clinical Electroencephalography, 1993
The midline theta rhythm consists of runs of theta waves occurring in the midline, especially in the central and parietal vertex regions. Few reports regarding this uncommon EEG finding have been published. It has been given various names, e.g. theta discharges in the middle-line, theta spindles, etc. Out of the 4,236 patients who were administered EEG
