q3 i? Stimulation immediately upon spindle detection appeared to truncate the stimulated spindle approximately 500 ms post-stimulation, whereas delayed stimulation produced increased spindle activity without shortening. → Jourde 2026

q3 · i? · causal · r2

In the nap study's electrophysiological analysis, "stimulation appeared to truncate the stimulated spindle ∼500 ms post" in the immediate condition, while the delayed condition showed increased spindle activity post stimulation without truncation.

"In the 'SP' condition, stimulation appeared to truncate the stimulated spindle ∼500 ms post, corroborating earlier results51."
